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.
At what time history did the liberal
movement enjoys its heyday?
When we are young, we learn that
tigers and sharks are dangerous animals. We might be scared of them because
they are big and powerful. As we get older, however, we learn that sometimes
the most dangerous animals are also the smallest animals. In fact, the animal
that kills the most people every year is one that you have probably killed
yourself many times: the mosquito.
While it may seem that all
mosquitoes are biters, this is not actually the case. Male mosquitoes eat plant
nectar. One the other hand, female mosquitoes feed on animal blood. They need
this blood to live and produce eggs. When a female mosquito bites a human
being, it transmits a small amount of saliva into the blood. The saliva may or
may not contain a deadly disease. The result of the bite can be as minor as an
itchy bump or as serious as death.
Because a mosquito can bite many
people in the course of its life, it can carry diseases from one person to
another very easily. Two of the most deadly diseases carried by mosquitoes are
malaria and yellow fever. More than 700 million people become sick from these
diseases every year. At least 2 million of these people will die from these
diseases.
Many scientists are working on
safer and better ways to kill mosquitoes, but so far, there is no sure way to
protect everyone in the world from their deadly bites. Mosquito nests can be
placed over beds to protect people against being bitten. These nets help people
stay safe at night, but they do not kill any mosquitoes. Mosquitoes have many
natural enemies like bats, birds, dragonflies, and certain kinds of fish.
Bringing more of these animals into places where mosquitoes live might help to
cut down the amount of mosquitoes in that area. This is a natural solution, but
is does not always work very well. Mosquitoes can also be killed with poisons
or sprays. Even though these sprays kill mosquitoes, they may also harm other
plants or animals.
Although mosquitoes may not seem
as scary as larger, more powerful animals, they are far more dangerous to human
beings. But things are changing. It is highly likely that one day scientists
will find a way to keep everyone safe from mosquitoes and the diseases they
carry.
In paragraph 2 the author writes, “This
saliva may or may not contain a deadly disease.” The purpose of this statement
is to
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.
The word “square” as used in the passage means
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.
According to the passage which of the following is not true?
First introduced in 1927, The Hardy
Boys Mystery Stories are a series of books about the adventures of brothers
Frank and Joe Hardy, teenaged detectives who solve one baffling mystery after
another. The Hardy Boys were so popular among young boys that in 1930 a similar
series was created for girls featuring a sixteen-year-old detective named Nancy
Drew. The cover of each volume of The Hardy Boys states that he author of the
series is Franklin W. Dixon; the Nancy Drew Mystery Stories are supposedly
written by Carolyn Keene. Over the years, though, many fans of both series have
been surprised to find out that Franklin W. Dixon and Carolyn Keene are not
real people. If Franklin W. Dixon and Carolyn Keene never existed, then who
wrote The Hardy Boys and Nancy Drew mysteries?
The Hardy Boys and the Nancy Drew
books were written through a process called ghostwriting. A ghostwriter writes
a book according to a specific formula. While ghostwriters are paid for writing
the books, their authorship is not acknowledged, and their names do not appear
on the published books. Ghostwriters can write books for children or adults,
the content of which is unspecific. Sometimes they work on book series with a
lot of individual titles, such as The Hardy Boys and the Nancy Drew series.
The initial idea for both The Hardy
Boys and the Nancy Drew series was developed by a man named Edward Stratemeyer,
who owned a publishing company that specialized in children’s book.
Stratemeyer noticed the increasing
popularity of mysteries among adult, and surmised that children would enjoy
reading mysteries about younger detectives with whom they could identify.
Stratemeyer first developed each book with an outline describing the plot and
setting. Once he completed the outline, Stratemeyer then hired a ghostwriter to
convert it into a book of slightly over 200 pages. After the ghostwriter had
written a draft of a book, he or she would send it back to Stratemeyer, who
would make a list of corrections and mail it back to the ghostwriter. The
ghostwriter would revise the book according to Stratemeyer’s instructions and
then return it to him. Once Stratemeyer approved the book, it was ready for
publication.
Because each series ran for so many
years, Nancy Drew and The Hardy Boys both had a number of different
ghostwriters producing books; however, the first ghostwrites for each series proved
to be the most influential. The initial ghostwriter for The Hardy Boys was a
Canadian journalist named Leslie McFarlane. A few years later, Mildred A. Wirt,
a young writer from lowa, began writing the Nancy Drew books. Although they
were using prepared outlines as guides, both McFarlane and Wirt developed the
characters themselves. The personalities of Frank and Joe Hardy and Nancy arose
directly from McFarlane’s and wirt’s imaginations. For example, Mildred Wirt
had been a star college athelete and gave Nancy similar athletic abilities. The
ghostwriters were also responsible for numerous plot and setting details.
Leslie McFarlane used elements of his small C fictional hometown.
Although The Hardy Boys and Nancy
Drew books were very popular with children, not everyone approved of them.
Critics thought their plots were unrealistic and even far-fetched, since most
teenagers did not experience the adventures Frank and Joe Hardy or Nancy Drew
did. The way the books were written also attracted criticism. Many teachers and
librarians objected to the ghostwriting process, claiming it was designed to
produce books quickly rather than create quality literature. Some libraries –
including the New York Public Library – even refused to include the books in
their children’s collections. Ironically, this decision actually helped sales
of his books, because children simply purchased them when they were unavailable
in local libraries.
Regardless of the debates about
their literary merit, each series of books has exerted an undeniable influence
on American and even global culture. Most Americans have never heard of Edward
Stratemeyer, Leslie McFarlane, or Mildred wirt, but people throughout the world
are familiar with Nancy Drew and Frank and Joe Hardy.
Which of the following best
describes the author’s attitude towards The Hardy Boys and Nancy Drew book
series?
Each nation has its own peculiar character
which distinguishes it from others. But the people of the world have more
points in which they are all like each other than points in which they are
different. One type of person that is common in every country is the one who
always tried to do as little as he possibly can and to get as much in return as
he can. His opposite, the man who is in the habit of doing more than is
strictly necessary and is ready to accept what is offered in return, is rare
everywhere.
Both these types are usually unconscious of
their character. The man who avoids effort is always talking about his ‘rights’;
he appears to think that society owes him a pleasant easy life. The man who is
always doing more than his sheer talks of ‘duties’ feels that the individual is
in debt to society, and not society to the individual. As a result of their
view, neither of these men thinks that he behaves at all strangely.
What type of person is common in every nation?
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.
It can be inferred from the passage
that Whately found Dickens’ characters to be
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.
According to the paragraph 2,
which of the following is directly responsible for energy production?
What are good parts of our civilization? First and fore-most there are
order and safety. If today I have a quarrel with another man, I do not get
beaten merely because I am physically weaker and he can knock me down. I go to
law and the law will decide as fairly as it can between the two of us. Thus in
disputes between man and man. Right has taken the place might. More-over, the
law protects me from robbery and violence. Nobody may came and break into my
house, steal my books or run off with my children. Of course, there are
burglars, but they are very rare and the law punishes them whenever it catches
them.
It is difficult for us to realize how much this safety means. Without
safety those higher activates of mankind which make up civilization could not
go on. The inventor could not invent, the scientist find out or the artist make
beautiful things. Hence, order and safety, although they are not themselves
civilization, are things without which civilization could be impossible. They
are as necessary to our civilization as the air we breathe is to us; and we
have grown so used to them that we do not notice them any more than we notice
the air.
According to the passage, the burglars are:
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.
