The history of civilization shows how man
always has to choose between making the right and wrong use of the discoveries
of science. This has never been more true than in our own age. In a brief
period amazing discoveries have been made and applied to practical purpose.
It would be ungrateful not to recognize how
immense are the boons which science has given to mankind. It has brought within
the reach of multitudes benefits and advantages which only a short time ago
where the privilege of the few. It has shown how malnutrition, hunger and
disease can be overcome. It has not only
lengthened life but it has depended to his quality. Fields of knowledge,
experience and recreation open in the past only to few, have been thrown open
to million. Through the work of science the ordinary man today has been given
the opportunity of a longer and fuller life than was ever possible to his
grandparents.
Amazing discoveries of science have been made:
The year 2006 was the golden
anniversary, or the 50th birthday, of the Dwight D. Eisenhower
National System of Interstate and Defense Highways. This system, usually
referred to as The Interstate Highway System, is a system of freeways named
after the U.S. President who supported it. The system is the largest highway
system in the world, consisting of 46,876 miles (75,440 km) of freeways. The
construction of the interstate highway system is an important part of American
history. It has played a major role in preserving and maintaining the America way of life.
The interstate highway system has
several major functions. One of its major functions is to facilitate the distribution of US good. Because the
intestate passes through many downtown areas, it plays an important role in the
distribution of almost all goods in the United States.
Nearly all products travel at least part of the way to their destination on the
Interstate System. Another major function of the interstate is to facilitate
military troop movement to and from airports, seaports, rail terminals and
other military destinations. The Interstate highways are connected to route in
the Strategic Highway Network, which is a system of highways that are vital to the U.S. Department of Defense.
Today, most of the Interstate system
consists of newly constructed highways. The longest section of the Interstate
system runs from Boston, Massachusetts to Seattle, Washington. It covers
3,020.54 miles. The shortest two-digit interstate is from Emery, North Caroline
to Greensboro, North Caroline. It covers only 12.27 miles. All state capitals
except five are served by the system. The five that are not directly served are
Juneau, AK, Dover, DE, Jefferson City, MO, Carson City, NV, and Pierre, SD. The
Interstate Highway System serves almost all major U.S. cities.
EACH Interstate highway is marked
with a red, white, and blue shield with the word “Interstate,” the name of the
state, and the route number. Interstate highways are named with one or
two-digit numbers. North-south highways are designated with odd numbers; east-west highways are
named with even numbers. The north-south Interstate highways begin in the west
with the lowest odd number; the east-west highways begin in the south with the
lowest even numbers. There all mile markers at each mile of the interstate
system, starting at the westernmost or southernmost point on the highway. Every
Interstate highway begins with the number “0”. Interchanges are numbered
according to their location on the highway in relation to mileage; an exit
between milepost 7 and milepost 8 would be designated “Exit 7.” This system
allows drivers estimate the distance to a desired exit, which a road is leading
off the highway. Despite the common acceptance of the numbering system on the
Interstate highways, some states have adopted different numbering systems. For
example, a portion of the Interstate 19 in Arizona is measured in kilometers
instead of miles since the highway goes south to Mexico.
Since the Interstate highways are
freeways-highways that do not have signs and cross streets – they have the
highest speed limits in the nation. Most interstate highways have speed limits
between 65 – 75 miles per hour (105 – 120 kilometers per hour), but some areas
in Texas and Utah have an 80 mile-per-hour (130 kilometer-per-hour) speed
limit.
The federal government primarily
funds interstate highways. However, they are owned and operated by the
individual states or toll authorities in the states. The federal government
generally funds up to 90% of the cost of an Interstate highway, while the
states pay the remainder of the cost.
Something vital is very

Which
of the following can be overcome with the help of science?
When her grandmother’s health began to deteriorate in the
fall of 1994, Mary would make the drive from Washington, DC to Winchester every
few days.
She hated highway driving, finding it ugly and monotonous. She
preferred to take meandering back roads to her grandmother’s hospital. When she
drove through the rocky town of Harpers Ferry, the beauty of the rough waters
churning at the intersection of the Shenandoah and Potomac rivers always
captivated her.
Toward the end of her journey, Mary had to get on highway
81. It was here that she discovered a surprising bit of beauty during one of
her trips. Along the median of the highway, there was a long stretch of
wildflowers. They were thin and delicate and purple, and swayed in the wind as
if whispering poems to each other.
The first time she saw the flowers, Mary was seized by an uncontrollable
urge to pull over on the highway and yank a bunch from the soil. She carried
them into her grandmother’s room when she arrived at the hospital and placed
them in a water pitcher by her bed. For a moment her grandmother seemed more
lucid than usual. She thanked Mary for the flowers, commented on their beauty
and asked where she had gotten them. Mary was overjoyed by the ability of the
flowers to wake something up inside her ailing grandmother.
Afterwards, Mary began carrying scissors in the car during
her trips to visit her grandmother. She would quickly glide onto the shoulder,
jump out of the car, and clip a bunch of flowers. Each time Mary placed the
flowers in the pitcher, her grandmother’s eyes would light up and they would
have a splendid conversation.
One morning in late October, Mary got a call that her
grandmother had taken a turn for the worse. Mary was in such a hurry to get to
her grandmother that she sped past her flower spot. She decided to turn around
head several miles back, and cut a bunch. Mary arrived at the hospital to find her
grandmother very weak and unresponsive. She placed flowers in the pitcher and
sat down. She felt a squeeze on her fingers. It was the last conversation they
had.
As used in the middle of the story, which is the best antonym for ‘lucid’?
Educational planning should aim at meeting the educational needs
of the entire population of all age group. 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
as any university professor. The retired and the age 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 adult for various forms of self – learning. A
viable education system of the future should consist of modules with different
kinds of functions serving a diversity of constituents. 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 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
organizations such as libraries. Museums, municipal recreational programs,
health services etc.
Integrating the concept of
lifelong learning with the educational structure would imply
Chocolate – there’s nothing quite like it, is there?
Chocolate is simply delicious. What is chocolate? Where does it come from?
Christopher Columbus was probably the first to take cacao
beans from the New World to Europe in around 1502. But the history of chocolate
goes back at least 4,000 years! The Aztecs, who lived in America, through that
their bitter cacao drink was a divine gift from heaven. In fact, the scientist
Carolus Linnaeus named the plant Theobroma, which means “food of the gods”
The Spanish explorer Hernando Cortex went to America in
1519. He visited the Mexican emperor Montezuma. He saw that Montezuma drank
cacao mixed with vanilla and spices. Cortez took some cacao home as a gift to the
Spanish King Charles. In Spain, people began to drink Cortez’s chocolate in
drink with chili peppers. However, the natural taste of cacao was too bitter
for most people. To sweeten the drink, Europeans added sugar to the cacao
drink. As a sweet drink, it became more popular. By the 17th
century, rich people in Europe were drinking it.
Later, people started using chocolate in pastries, like pies and cakes. In 1828, Dutch chocolate
makers started using a new process for removing the fat from cacao beans, and
getting to the center of the cacao bean. The Dutch chocolate maker Conrad J.
Van Houten made a machine that pressed the fat from the bean. The resulting powder
mixed better with water than cacao did. Now, some call van Houten’s chocolate “Dutch
chocolate.”
It was easy to mix Dutuch chocolate powder with sugar. So
other chocolate makers started trying new recipes that used powdered chocolate. People started
mixing sweetened chocolate with cocoa butter to make solid chocolate bars. In
1849, an English chocolate maker made the first chocolate bar. In the 19th
century, the Swiss started making milk chocolate by mixing powdered milk with
sweetened chocolate. Milk chocolate has not changed much since this process was
invented.
Today, two countries – Brazil and Ivory Coast – account for
almost half the world’s chocolate. The United States imports most of the
chocolate in the world, but the Swiss eat the most chocolate per person. The
most chocolate eaten today is sweet milk chocolate, but people also eat white
chocolate and dark chocolate.
Cocoa and dark chocolate are believed to help prevent heart
attacks, or help keep from happening. They are supposed to be good for the
circulatory system. On the other hand, the high fat content of chocolate can
cause weight gain, which is not good for people’s health. Other health claims
for chocolate have not been proven, but some research shows that chocolate
could be good for the brain.
Chocolate is a popular holiday gift. A popular Valentine’s
Day gift is a box of chocolate candies with a card and flowers. Chocolate is
sometimes given for Christmas and birthdays. Chocolate eggs are sometimes given
at Easter.
Chocolate is toxic to some animals. An ingredient in chocolate
is poisonous to dogs, cats, parrots, small rodents, and some livestock. Their
bodies cannot process some if the chemicals found in chocolate. Therefore, they
should never be fed chocolate.
If something is toxic it is
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.
In what epochs of modern history
have men especially contributed to the emancipation of human race?
At the time Jane Austen’s novels
were published – between 1811 and 1818 – English literature was not part of any
academic curriculum. In addition, fiction was under strenuous attack. Certain
religious and political groups felt novels had the power to make so-called
immoral characters so interesting that young readers would identify with them;
these groups also considered novels to be of little practical use. Even
Coleridge, certainly no literary reactionary, spoke for many when the asserted
that “novel-reading occasions the destruction of the mind’s powers.”
These attitudes towards novels help
explain why Austen received little attention from early nineteenth-century
literary cities. (In any case a novelist published anonymously, as Austen was,
would not be likely to receive much critical attention.) The literary response
that was accorded to her, however, was often as incisive as twentieth-century
criticism. In his attack in 1816 on novelistic portrayals “outside of ordinary experience,”
for example. Scott made an insightful remark about the merits of Austen’s
fiction.
Her novels, wrote Scott, “present to
the reader an accurate and exact picture of ordinary everyday people and
places, reminiscent of seventeenth-century Flemish painting.” Scott did not use
the word ‘realism’, but he undoubtedly used a standard of realistic probability
in judging novels. The critic Whately did not use the word ‘realism’, either,
but he expressed agreement with Scott’s evaluation, and went on to suggest the possibilities
for moral instruction in what we have called Austen’s ‘realistic method’ her
characters, wrote Whately, are persuasive agents for moral truth since they are
ordinary persons “so clearly evoked that we feel an interest in their fate as
if it were our own.” Moral instruction, explained Whately, is more likely to be
effective when conveyed through recongnizably human and interesting characters
than when imparted by a sermonizing narrator. Whitely especially praised Austen’s
ability to create character who “mingle goodness and villainy, weakness and
virtue, as in life they are always mingled. “Whitely concluded his remarks by
comparing Austen’s art of characterization to Dickens’, starting his preference
for Austen’s.
Yet, the response of
nineteenth-century literary critics to Austen was not always so laudatory, and
often anticipated the reservations of twentieth-century literary critics. An
example of such a response was Lewes complaint in 1859 that Austen’s range of
subject and characters was too narrow. Praising her verisimilitude, Lewes added
that, nonetheless her focus was too often only upon the unlofty and the
commonplace. (Twentieth-century Marxists, on the other hand, were to complain
about what they saw as her exclusive emphasis on a lofty upper middle class.)
In any case having being rescued by literary critics from neglect and indeed
gradually lionized by them, Austen steadily reached, by the mid-nineteenth
century, the enviable pinnacle of being considered controversial.
The author mentions that English
literature “was nor part of any academic curriculum” in the early nineteenth
century in order to
Fleas are perfectly designed by
nature to feast on anything containing blood. Like a shark in the water or a
wolf in the woods, fleas are ideally equipped to do what they do, making them
very difficult to defeat. The bodies of these tiny parasites are extremely
hardy and well-suited for their job.
A flea has a very hard exoskeleton,
which means the body is covered by a tough, tile-like plate called a sclerite.
Because of these plates, fleas are almost impossible to squish. The
exoskeletons of fleas are also waterproof of fleas are also waterproof and shock
resistant, and therefore fleas are highly resistant to the sprays and chemicals
used to kill them.
Little spines are attached to his
plate. The spine the flea scurries through an animal’s fur in – search of
grooming pet tries to pull a flea off through the hair coat, these spines will
extend and stick to the fur like Velcro.
Fleas are some of the best jumpers
in the natural world. A flea can jump seven inches, or 150 times its own
length, either vertically or horizontally. An equivalent jump for a person
would be 555 feet, the height of the Washington Monument. Fleas can jump 30,000
times in a row without stopping, and they are able to accelerate through the
air at an incredibly high rate – a rate which is over ten times what humans can
withstand in an airplane.
Fleas have very long rear legs with
huge thigh muscles and multiple joints. When they get ready to jump. They fold their
long legs up and crouch like a runner on a staring block. Several of their
joints contain a protein called resilin, which helps catapult fleas into the
air as they jump, similar to the way a rubber band provides momentum to a
slingshot. Outward facing claws on the bottom of their legs grip anything they
touch when they land.
The adult female flea mates after
her first blood meal and begins producing eggs in just 1 to 2 days. One flea
can lay up to 50 eggs in one day and over 2,000 in her lifetime. Flea eggs can
be seen with the naked eye, but they are about the size of a grain of salt. Shortly
after being laid, the eggs begin to transform into cocoons. In the cocoon
state, fleas are fully developed adults, and will hatch immediately if
conditions are favorable. Fleas can detect warmth, movement, and carbon dioxide
in exhaled breath, and these three factors stimulate them to emerge as new
adults. If the flea does not detect appropriate conditions, it can remain
dormant in the cocoon state for extended periods. Under ideal conditions, the
entire life cycle may only take 3 weeks, so in no time at all, pets and homes
can become infested.
Because of these characteristics,
fleas are intimidating opponents. The best way to control fleas, therefore, is
to take steps to prevent an infestation from ever occurring.
The author’s tone in the passage is
best described as
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.
Based on information in the final
paragraph, which of the following statements would the author likely agree with?
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.
Which of the following,
according to the passage, it compared with dearness allowance?
