Question # 1
The hammer may be oldest tool we have record of. Stone hammers-some of the oldest human artifacts ever discovered-date back as early as 2,600,000 BCE. Not only is the hammer the oldest tool, but it is also the greatest. What make the hammer so great is its simplicity, power, and usefulness.The structure of the hammer is relatively simple-a fact largely responsible for its early invention and widespread distribution across cultures and geographic regions. The hammer is composed of two main parts: a handle and a head. The handle is used to swing the hammer. The head is used to hit other objects.While the hammer is a very simple tool, it is still able to generate tremendous power. This power results from two factors: the weight of the head, and the speed at which the hammer is swung. Every hammer (though some more than other) has a large distribution of weight at the head. When a hammer is swung, this weight pivots about the hand, which acts as a fulcrum. The handle carries the weight at a distance, acting as a lever arm, so a longer handle means increased speed. The weight of the head together with the speed generated by the lever arm is what gives the hammer so much power.The heavier the head and the faster it is swung, the more power a hammer produces.In addition to the hammer's great power, it also has an exceptionally wide range of useful applications. The purpose of the hammer -- to hit-- is a universal action that can accomplish many tasks. Let's start with the obvious: a hammer can be made to pound nails. But a hammer has many other uses as well. It can break apart hard objects such as brick or concrete. It can bend and shape metal or steel. It can gently tap objects to make small adjustments. It can be used to make sculpture or pottery. It can be used in the hot, harsh business of blacksmithing as well as in delicate operations like crafting jewelry. In times of desperation, it can even be used as a weapon.The hammer truly is a great tool. It is simple, powerful, and useful. A quintessential symbol of labor, the hammer has come to represent hard work and embody the spirit of human industry.
Question:
Which of the following best describes the organization of this passage?
Question # 2
The public distribution system, which provides food at low
prices, is a subject of vital concern. There is a growing realization that
thought Pakistan has enough food to feed its masses three square meals a day,
the monster of starvation and food insecurity continues to haunt the poor in
our country.
Increasing the purchasing power of the poor through
providing productive employment leading to rising income, and thus good standard
of living is the ultimate objective of public policy. However, till then, there
is a need to provide assured supply of food through a restructured more
efficient and decentralized public distribution system (PDS).
Although the PDS is extensive – it is one of the largest
such systems in the world – it has yet to reach the rural poor and the far off
places. It remains an urban phenomenon, with the majority of the rural poor
still out of its reach due to lack of economic and physical access. The poorest
in the cities and the migrants are left out, for they generally do not possess
ration cards. The allocation of PDS supplies in big cities is larger than in
rural areas. In view of such deficiencies in the system, the PDS urgently needs
to be streamlined. In addition, considering the large food grains production
combined with food subsidy on one hand and the continuing slow starvation and dismal
poverty of the rural population on the other, there is a strong case for making
PDS target group oriented.
The growing salaried class is provided job security, regular
income, and percent insulation against inflation. These gains of development
have not percolated down to the vast majority of our working population. If one
compares only dearness allowance to the employees in public and private sector
and looks at its growth in the past few years, the rising food subsidy is
insignificant to the point of inequity. The food subsidy is a kind of D.A. to
the poor, the self-employed and those in the unorganized sector of the economy.
However, what is most unfortunate is that out of the large budget of the so –
called food subsidy, the major part of it is administrative cost and wastages.
A small portion of the above budget goes to the real consumer and an even
lesser portion to the poor who are in real need.
It is true that subsidies should not become a permanent feature
except for the destitute, disabled widows and the old. It is also true that
subsidies often create a psychology of dependence and hence is habit – forming,
killing the general initiative of the people. By making PDS target group
oriented, not only the poorest and neediest would be reached without additional
cost, but it will actually cut overall costs incurred on large cities and for
better off localities. When the food and food subsidy are limited the rural and
urban poor should have the priority in the PDS supplies. The PDS should be
closely linked with programs of employment generation and nutrition
improvement.
What, according to the passage, is be the main purpose of
public policy in the long run?

Question # 5
It is easy to make delicious-looking hamburger at home. But would this
hamburger still look delicious after it sat on your kitchen table under very
bright lights for six or seven hours? if someone took a picture or made a video
of this hamburger after the seventh hour, would anyone want to eat it? More
importantly, do you think you could get millions of people to pay money for
this hamburger? These are the questions that fast food companies worry about
when they produce commercials or print ads for their products. Video and photo
shoots often last many hours. The lights that the photographers use can be
extremely hot. These conditions can cause the food to look quite unappealing to
potential consumers. Because of this, the menu items that you see in fast food
commercials are probably not actually edible.Let's use the hamburger as an
example. The first step towards building the commercial hamburger is the bun.
The food stylist--a person employed by the company to make sure the products
look perfect--sorts through hundreds of buns until he or she finds one with no
wrinkles. Next, the stylist carefully rearranges the sesame seeds on the bun
using glue and tweezers for maximum visual appeal. The bun is then sprayed with
a waterproofing solution so that it will no get soggy from contact with other
ingredients, the lights, or the humidity in the room.Next, the food stylist
shapes a meat patty into a perfect circle. Only the outside of the meat gets
cooked-the inside is left raw so that the meat remains moist. The food stylist
then paints the outside of the meat patty with a mixture of oil, molasses, and
brown food coloring. Grill marks are either painted on or seared into the meat
using hot metal skewers.Finally, the food stylist searches through dozens of
tomatoes and heads of lettuce to find the best-looking produce.One leaf of the
crispest lettuce and one center slice of the reddest tomato are selected and
then sprayed with glycerin to keep them looking fresh. So the next time you see
a delectable hamburger in a fast food commercial, remember: you are actually
looking at glue, paint, raw meat , and glycerin. Are you still hungry?

Question # 7
Although cynics may like to see he government’s policy for
women in terms of the party’s internal power struggles, it will nevertheless be
churlish to deny that it represents a pioneering effect aimed at bringing about
sweeping social reforms. In its language, scope and strategies, the policy documents
displays a degree of understanding of women’s needs that is uncommon in
government pronouncements. This is due in large part to the participatory
process that marked its formulation, seeking the active involvement right from
the start of women’s groups, academic institutions and non-government
organizations with grass roots experience. The result is not just a lofty
declaration of principles but a blueprint for a practical program of action.
The policy delineates a series of concrete measures to accord women a
decision-making role in the political domain and greater control over their
economic status. Of especially far-reaching impart are the devolution of
control of economic infrastructure to women, notably at the gram panchayat
level, and the amendment proposed in the Act of 1956 to give women comparcenary
rights.
And enlightened aspect of the policy is its recognition that
actual change in the status of women cannot be brought about by the mere enactment
of socially progressive legislation. Accordingly, it focuses on reorienting
development programs and sensitizing administrations to address specific
situations as, for instance, the growing number of households headed by women,
which is a consequence of rural-urban migration. The proposal to create an
equal-opportunity police force and give women greater control of police
stations is an acknowledgement of the biases and callousness displayed by the
generally all-male law-enforcement authorities in case of dowery and domestic
violence. While the mere enunciation of such a policy has the salutary effect
of sensitizing the administration as a whole, it does not make the task of its
implementation any easier. This is because the changes it envisages in the
political and economic status of woman strike at the root of power structures
in society and the basis of man-woman relationship. There is also the danger
that reservation for women in public life, while necessary for their greater
visibility, could lapse into tokenism or become a tool in the hands of vote
seeking politicians. Much will depend on the dissemination of the policy and
the ability of elected representatives and government agencies to reorder their
priorities.
Which of the following is true about the policy?
Question # 8
Recent advances in science and technology have made it
possible for geneticists to find out abnormalities in the unborn foetus and
take remedial action to rectify some defects which would otherwise prove to be
fatal to the child. Though genetic engineering is still at its infancy,
scientists can now predict with greater accuracy a genetic disorder. It is not
yet an exact science since they are not in a position to predict when exactly a
genetic disorder will set in. While they have not yet been able to change the
genetic order of the gene in germs, they are optimistic and are holding out
that in the near future they might be successful in achieving this feat. They
have, however, acquired the ability in manipulating tissue cells. However,
genetic mis-information can sometimes be damaging for it may adversely affect
people psychologically. Genetic information may lead to a tendency to brand
some people as inferiors. Genetic information can therefore be abused and its
application in deciding the sex of the foetus and its subsequent abortion is
now hotly debated on ethical lines. But on this issue geneticists cannot be
squarely blamed though this charge has often been leveled at them. It is mainly
a societal problem. At present genetic engineering is a costly process of
detecting disorders but scientists hope to reduce the costs when technology
becomes more advanced. This is why much progress in this area has been possible
in scientifically advanced and rich countries like the U.S.A., U.K. and Japan.
It remains to be seen if in the future this science will lead to the
development of a race of supermen or will be able to obliterate disease from
this world.
Which of the following is not true of the genetic
engineering movement?
Question # 9
The history of the modern world is a
record of highly varied activity, of incessant change, and of astonishing
achievement. The lives of men have, during the last few centuries, increasingly
diversified, their powers have greatly multiplied, their powers have greatly
multiplied, their horizon been enormously enlarged. New interests have arisen
in rich profusion to absorb attention and to provoke exertion. New aspirations
and new emotions have come to move the soul of men. Amid all the bewildering phenomena,
interest, in particular, has stood out in clear and growing pre-eminence, has expressed
itself in a multitude of ways and with an emphasis more and more pronounced,
namely, the determination of the race to gain a larger measure of freedom than
it has ever known before, freedom in the life of the intellect and spirit,
freedom in the realm of government and law, freedom in the sphere of economic
and social relationship. A passion that has prevailed so widely, that has transformed
the world so greatly, and is still transforming it, is one that surely merits
study and abundantly rewards it, its operations constitute the very pith and
marrow of modem history.
Not that this passion was unknown to
the long ages that proceeded the modern periods. The ancient Hebrews, the
ancient Greeks and Roman blazed the was leaving behind them a precious heritage
of accomplishments and suggestions and the men who were responsible for the
Renaissance of the fifteenth century and the Reformation of the sixteen century
contributed their imperishable part to this slow and difficult emancipation of
the human race. But it is in modern times the pace and vigour, the scope and
sweep of this liberal movement have so increased unquestionably as to dominate
the age, particularly the last three centuries that have registered great
triumphs of spirit.
The operation of which factor
constitutes the pith and marrow of modern history?
Question # 10
Philadelphia is a city known for
many things. It is where the Declaration of independence was signed in 1776,
and it was also the first capital of the United States. But one fact about Philadelphia
is not so well-known: it is home to nearly 3,000 murals painted on the sides of
homes and buildings around the city. In fact, it is said that Philadelphia has
more murals than any other city in the world, with the exception of Rome. How
did this come to be?
More than 20 years ago, a New
Jersey artist named Jane Golden started a program pairing troubled youth with
artists to paint murals on a few buildings around the city. Form this small
project, something magical happened. The young people involved helped to create
magnificent pieces of art, but there were other, perhaps more important
benefits. The young people learned to collaborate and get along with many
different kinds of people during the various steps required to paint and design
a mural. They learned to be responsible, because they needed to follow a
schedule to make sure the murals were completed. They also learned to take pride
in their community. It is hard for any resident to see the spectacular designs
and not feel proud to be a part of Philadelphia.
Take a walk around some of the
poorest neighborhoods I Philadelphia, neighborhoods full of broken windows and
littered front steps, and you will find beautiful works of art on the sides and
fronts of buildings. Of course they murals are not just in poor neighborhoods,
but more affluent ones as well. Special buses take tourists to different parts
of the city to see the various murals, which range from huge portraits of
historical heroes, to cityscapes, to scenes depicting the diverse ethnic groups
that call Philadelphia home.
As a result of its success, the
mural program created by Jane Golden has now become the nation’s largest public
art program and a model for to troubled youth.
As used in paragraph 1, the phrase
“with the exception Rome” means that

Yellowstone National Park is the
U.S. States of Wyoming, Idaho and Montana. It became the first National Park in
1872. There are geysers and hot springs at Yellowstone. There are also many
animals at Yellowstone. There are elk, bison, sheep, grizzly, black bears,
moose, coyotes, and more.
More than 3 million people visit
Yellowstone National Park year. During the winter, visitors can ski or go
snowmobiling there. There are also snow coaches that give tours. Visitors can
see steam (vapor water) come from the geysers. During
other seasons, visitors can go boating or fishing. People can ride horses
there. There are nature trails and tours. Most visitors want to see Old
Faithful, a very predictable geyser at
Yellowstone Visitors can check a schedule to see the exact time that Old
Faithful is going to erupt. There are many other geysers and boiling springs in
the area. Great Fountain Geyser erupts every 11 hours. Excelsior Geyser
produces 4,000 gallons of boiling water each minute! Boiling water is 100
degrees Celsius, or 212 degrees Fahrenheit – that’s very hot! People also like
to see the Grand Prismatic Spring. It is the largest hot spring in the park. It
has many beautiful colors. The beautiful colors are caused by bacteria in the water. These are forms of life that
have only one cell. Different bacteria live in different water temperatures. Visiting Yellowstone National Park can be a week
– long vacation or more. It is beautiful and there are activities for everyone.
What causes colors in the springs?
A. Sunlight
B. Bacteria
C. Eruptions
D. Temperatures

Q.4 Educational planning should aim at meeting the educational needs of the entire population of all age groups while the traditional structure of education as a three layer hierarchy from the primary stage to the university represents the core we should not overlook the periphery which is equally important Under modern conditions workers need to rewind or renew their enthusiasm or strike out in a new direction or improve their skills as much any university professor the retired and the aged have their needs as well Educational planning in their words should take care of the needs of everyone.Our structures of education have been built up on the assumption that there is a terminal point to education This basic defect has become all the more harmful today.A UNESCO report entitled Learning to be prepared by Edgar Faure and others in 1973 asserts that the education of children must prepare the future should consist of modules with different kinds of functions serving a diversity of constituent And performance not the period of study should be the basis for credentials the writing is already on the wall In view of the fact that the significance of a commitment of lifelong learning and lifetime education is being discussed only in recent years even in educationally advanced countries the possibility of the idea becoming an integral part of the idea becoming an integral part of educational thinking seems to be a far cry For to move in that direction means such more than some simple rearrangement of the present organization of education but a good beginning can be made by developing open university programs for older learners of different categories and introducing extension services in the conventional colleges and schools also these institutions should learn to cooperate with the numerous community municipal recreational programs health services etc.
f.According to the author what measures should Open University adopt to meet modern conditions
A. Develop various programs for adult learners
B. Open more colleges on traditional lines
C. Cater to the needs of those who represent core
D. Primary education should be under the control of open universities

Gold used in jewelry is mixed with harder metals to add strength and durability. The metals added can also be used to change gold's color, giving it a for the natural yellow tone of pure gold. Mixtures like these, of less costly metals with more valuable ones, are called alloys. Copper and silver are the most common metals mixed with gold to make yellow gold jewelry. White gold is usually made with an alloy of gold and nickel.The measure of is called gold's purity is called a karat. The higher the karat rating, the higher the amount of pure gold. 24 karat is pure gold,18 karat is 75% pure gold, 14 karat is 58.5% pure gold,and 9 karat is 37.5% pure gold. All other things being equal, the higher the percentage of pure gold used in the alloy, the more valuable and expensive the jewelry will be.Gold jewelry pieces are usually stamped with a marking to identify the karat amount. White gold that is 24K is too soft for jewelry, 18K,14K and 9K gold are all appropriate for jewelry, and they all make pieces that look great and wear beautifully.
Question:
With respect to the relationship between gold and its karat rating, which of the following statements is/are true?
I. The lower the karat rating, the less pure the gold
II. The higher the karat rating, the more expensive the gold
III. The higher the karat rating, the more valuable the gold
A. I only
B. I andII only
C. II andIII only
D. I,II andIII

Right now, I am looking at a shelf
full or relics, a collection of has-beens, old-timers, antiques, fossils. Right
now I am lolling at a shelf full of books. Yes that’s right. If you have some
spare cash (the doing rate is about $89) and are looking to enhance your reading
experience, then I highly suggest you consider purchasing an e-reader.
E-readers are replacing the books of old, and I welcome them with open arms (as
you should).
If you haven’t heard of an e-reader
and don’t know what it is, then please permit the following explanation. An
e-reader is a device that allows you to read e-books. An e-book is a
book-length publication in digital form, consisting of text, images, or both,
and produced on, published through, and readable on computers or other
electronic devices. Sometimes the equivalent of a conventional printed book,
e-books can also be born digital. The Oxford Dictionary or English defines the
e-book as “an electronic version of a printed book, “but e-book can and do
exist without any printed equivalent.
So now you know what an e-reader is.
But you still may be wondering why they put printed books to shame. E-readers
are superior to printed books because they save space, are environmentally friendly,
and provide helpful reading tips and tools that printed books do not.
E-readers are superior to printed
books because they save space. The average e-reader can store thousands of
digital book, providing a veritable library at your fingertips. What is more,
being the size and weight of a thin hardback, the e-reader itself is relatively
petite. It is easy to hold and can fit in a pocketbook or briefcase easily. This
makes handling ponderous behemoths such as War and Peace, Anna Karenina, and
Les Miserables a breeze. Perhaps the only drawback to the space-saving aspect
of an e-reader is that it requires you to find new things to put on your
shelves.
In addition, e-readers are superior
to books because they are environmentally friendly. The average novel is about
300 pages long. So, if a novel is printed 1000 times, it will use 300,000
pieces of paper. That’s a lot of paper! If there are about 80,000 pieces of
paper in a tree, this means it takes almost 4 trees to make these 1000 books.
Now, we know that the average bestseller sells about 20,000 copies per week.
That means that it takes over 300 trees each month to sustain this rate. And
for the super bestsellers, these figures increase dramatically. For example,
the Harry Potter book series has sold over 450 million copies. That’s about 2
million trees! Upon viewing these figures, it is not hard to grasp the severe
impact of printed books on the environment. Since e-reader use no trees, they
represent a significant amount of preservation in terms of the environment and
its resources.
Finally, e-reader are superior to
books because they provide helpful reading tips and tolls that printed books do
not. The typical e-reader allows its user to customize letter size, font, and
line spacing. It also allows highlighting and electronic bookmarking.
Furthermore, it grants users the ability to get an overview of a book and then
jump to a specific electronic bookmarking. Furthermore, it grants users the
ability to get an overview of a book and then jump to a specific location based
on that overview. While these are all nice features, perhaps the most helpful
of all is the ability to get dictionary definitions at the touch of a finger.
On even the most basic e-reader, users can conjure instant definitions without
having to hunt through a physical dictionary.
It can be seen that e-readers are
superior to printed books. They save space, are environmentally friendly, and
provide helpful reading tips and tools that printed books do not. So what good
are printed books? Well, they certainly make nice decorations.
Based on its use in paragraph 4, It
can be inferred that petite belongs to which of the following word families?
A. Jubilant, euphoric, playful
B. Compact, diminutive, little
C. Cute, attractive, charming
D. Light, airy, spacious

On January 3, 1961, nine days after
Christmas, Richard Legg, John Byrnes, and Richard McKinley were killed in a
remote desert in eastern Idaho. Their deaths occurred when a nuclear reactor
exploded at a top-secret base in the National Reactor Testing Station (NRTS).
Official reports state that the explosion and subsequent reactor meltdown
resulted from the improper retraction of the control rod. When questioned about
the events that occurred there, officials were very reticent. The whole affair,
in fact, was discussed much, and seemed to disappear with time.
In order to grasp the mysterious
nature of the NRTS catastrophe, it help to know a bit about how nuclear
reactors work. After all, the generation of nuclear energy may strike many as
an esoteric process. However, given its relative simplicity, the way in which
the NRTS reactor functions is widely comprehensible. In this particular kind of
reactor, a cluster of nine-ton uranium fuel rods are positioned lengthwise
around a central control rod. The reaction begins with the slow removal of the
control ro, which starts a controlled nuclear reaction and begins to heat the
water in the reactor. This heat generates steam, which builds pressure inside
the tank. As pressure builds, the steam looks for a place to escape. The only
place this steam is able to escape is through the turbine. As it passes through
the turbine on its way out of the tank, it turns the giant fan blades and
produces energy.
On the morning of January 3, after
the machine had been shut down for the holidays, the three men arrived at the
station to restart the reactor. The control rod needed to be pulled out only
four inches to be reconnected to the automated driver. However, records
indicate that Byrnes yanked it out 23 inches, over five times the distance
necessary. In milliseconds the reactor exploded. Legg was impaled on the
ceiling; he would be discovered last. It took one week and a lead-shielded
crane to remove his body. Even in full protective gear, workers were only able
to work a minute at a time. The three men are buried in lead-lined coffins
under concrete in New York, Michigan, and Arlington Cemetery, Virginia.
The investigation took nearly two
years to complete. Did Byrnes have a dark motive? Or was it simply an accident?
Did he know how precarious the procedure was? Other operators were questioned
as to whether they knew the consequences of pulling the control rod out so far.
They responded “Of course! We often talked about what we would do if we were at
a radar station and the Russians came.
“We’d yank it out.”
Official reports are oddly
ambiguous, but what they do not explain, gossip does. Rumors had it that there
was tension between the men because Byrnes suspected the other two of being
involved with his young wife. There is little doubt than he, like the other
operators, knew exactly what would happen when he yanked the control rod.

Right now, I am looking at a shelf
full or relics, a collection of has-beens, old-timers, antiques, fossils. Right
now I am lolling at a shelf full of books. Yes that’s right. If you have some
spare cash (the doing rate is about $89) and are looking to enhance your reading
experience, then I highly suggest you consider purchasing an e-reader.
E-readers are replacing the books of old, and I welcome them with open arms (as
you should).
If you haven’t heard of an e-reader
and don’t know what it is, then please permit the following explanation. An
e-reader is a device that allows you to read e-books. An e-book is a
book-length publication in digital form, consisting of text, images, or both,
and produced on, published through, and readable on computers or other
electronic devices. Sometimes the equivalent of a conventional printed book,
e-books can also be born digital. The Oxford Dictionary or English defines the
e-book as “an electronic version of a printed book, “but e-book can and do
exist without any printed equivalent.
So now you know what an e-reader is.
But you still may be wondering why they put printed books to shame. E-readers
are superior to printed books because they save space, are environmentally friendly,
and provide helpful reading tips and tools that printed books do not.
E-readers are superior to printed
books because they save space. The average e-reader can store thousands of
digital book, providing a veritable library at your fingertips. What is more,
being the size and weight of a thin hardback, the e-reader itself is relatively
petite. It is easy to hold and can fit in a pocketbook or briefcase easily. This
makes handling ponderous behemoths such as War and Peace, Anna Karenina, and
Les Miserables a breeze. Perhaps the only drawback to the space-saving aspect
of an e-reader is that it requires you to find new things to put on your
shelves.
In addition, e-readers are superior
to books because they are environmentally friendly. The average novel is about
300 pages long. So, if a novel is printed 1000 times, it will use 300,000
pieces of paper. That’s a lot of paper! If there are about 80,000 pieces of
paper in a tree, this means it takes almost 4 trees to make these 1000 books.
Now, we know that the average bestseller sells about 20,000 copies per week.
That means that it takes over 300 trees each month to sustain this rate. And
for the super bestsellers, these figures increase dramatically. For example,
the Harry Potter book series has sold over 450 million copies. That’s about 2
million trees! Upon viewing these figures, it is not hard to grasp the severe
impact of printed books on the environment. Since e-reader use no trees, they
represent a significant amount of preservation in terms of the environment and
its resources.
Finally, e-reader are superior to
books because they provide helpful reading tips and tolls that printed books do
not. The typical e-reader allows its user to customize letter size, font, and
line spacing. It also allows highlighting and electronic bookmarking.
Furthermore, it grants users the ability to get an overview of a book and then
jump to a specific electronic bookmarking. Furthermore, it grants users the
ability to get an overview of a book and then jump to a specific location based
on that overview. While these are all nice features, perhaps the most helpful
of all is the ability to get dictionary definitions at the touch of a finger.
On even the most basic e-reader, users can conjure instant definitions without
having to hunt through a physical dictionary.
It can be seen that e-readers are
superior to printed books. They save space, are environmentally friendly, and
provide helpful reading tips and tools that printed books do not. So what good
are printed books? Well, they certainly make nice decorations.
As used in paragraph 1, it can be
inferred that “relics,” “has-been old timers, antiques, fossils” are all words
that describe something
A. Ancient
B. Useless
C. Outdated
D. Pathetic

The Baxter house is located at the
end of the street. This house sits farther back from the curb than the other
houses. It is almost difficult to see from the road without peering behind the
deformed oak tree that has obscured it for years. Even so, the Baxter house
stands out from the other houses on the street. It is tall and white. However,
this white is no longer pristinely white, but a dingy grayish cram color. Long
vines hang from the tattered roof. The Baxter house is two stories tall and has
a large yard in the back that has never been mowed. The other houses on the
street are a mere one story and have been painted a variety of colors. The
newer, single story properties all appear to have been built around the same time;
the yards mostly being of the same size, and the houses appearing to be clones
of one another. Aside from the Baxter house at the end, this street is a
perfect slice of middle America. The inhabitants of the other houses wonder who
lives in the ancient, dilapidated house at the end of the street.
Based on its use in the passage,
which of the following statements accurately describes something that has been ‘obscured’?
A. The tall, thick pine trees in Chloe's yard provide shade for her house
B. A sun visor is one of Ken's favorite hats, because it help protect his face from harsh rays
C. After it sopped raining, the sun was barely visible through the gray clouds
D. Because of his favorite, bright red sweatshirt, Anthony is always easy to spot

When you imagine the desert, you probably think of a very hot place covered with sand.Although this is a good description for many deserts. Earth's I with ice:Antarctica. In order for an area to be considered a desert, it must receive very little rainfall. More specifically, it must receive an average of less than ten inches of precipitation - which can be rain, sleet, hail , or snow - on the ground every year. Antarctica, the coldest place on earth, has an average temperature that usually falls below the freezing point. And because cold air holds less moisture than warm air, the air in Antarctica does not hold much moisture at all. This is evident in the low precipitation statistics recorded for Antarctica. For example , the central part of Antarctica receives an average of less than 2 inches of snow every year. The coastline of Antarctica receive a little bit more-between seven and eight inches a year. Because Antarctica gets so little precipitation every year, it is considered a desert. When precipitation falls in hot deserts, it quickly evaporates back into the atmosphere. the air over Antarctica is too cold to hold water vapor, so there is very little evaporation. Due to this low rate of evaporation, most of the snow that falls to the ground remains there permanently, eventually building up into thick ice sheets. Any snow that does not freeze into ice sheets becomes caught up in the strong winds that constantly blow over Antarctica. These snow-filled winds can make it look as if it is snowing. Even though snowfall is very rare there, blizzards are actually very common on Antarctica.
Question:
The best title for this passage would be
A. Earth's Many Deserts
B. Antarctica : The Coldest place on Earth
C. A Desert of Ice
D. Unusual Blizzards

Recent advances in science and technology have made it
possible for geneticists to find out abnormalities in the unborn foetus and
take remedial action to rectify some defects which would otherwise prove to be
fatal to the child. Though genetic engineering is still at its infancy,
scientists can now predict with greater accuracy a genetic disorder. It is not
yet an exact science since they are not in a position to predict when exactly a
genetic disorder will set in. While they have not yet been able to change the
genetic order of the gene in germs, they are optimistic and are holding out
that in the near future they might be successful in achieving this feat. They
have, however, acquired the ability in manipulating tissue cells. However,
genetic mis-information can sometimes be damaging for it may adversely affect
people psychologically. Genetic information may lead to a tendency to brand
some people as inferiors. Genetic information can therefore be abused and its
application in deciding the sex of the foetus and its subsequent abortion is
now hotly debated on ethical lines. But on this issue geneticists cannot be
squarely blamed though this charge has often been leveled at them. It is mainly
a societal problem. At present genetic engineering is a costly process of
detecting disorders but scientists hope to reduce the costs when technology
becomes more advanced. This is why much progress in this area has been possible
in scientifically advanced and rich countries like the U.S.A., U.K. and Japan.
It remains to be seen if in the future this science will lead to the
development of a race of supermen or will be able to obliterate disease from
this world.
Which of the following is the opposite in meaning to the
word ‘charged’ as used in the passage?
