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 same in meaning as the phrase ‘holding
out’ as used in the passage?
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 passage, it
can be understood that ‘dilapidated’ belongs to which of the following words
groups?
In the early 1920's,
settlers came to Alaska looking for gold. They traveled by boat to the coastal
towns of Seward and Knik, and from there by land into the gold fields. The
trail they used to travel inland is known today as the lditarod Trail, one of the
National Historic Trails designated by the congress of the United States. The
Iditarod Trail quickly became a major thoroughfare in Alaska, as the mail and
supplies were carried across this trail. People also used it to get from place
to place, including the priests, ministers, and judges who had to travel
between villages down this trail was via god sled.
Once the gold rush ended, many gold-seekers
went back to where they had come from, and suddenly there was much less travel
on the lditarod Trail. The introduction of the airplane in the late 1920's
meant dog teams were mode of transportation, of course airplane carrying the
mail and supplies, there was less need for land travel in general. The final
blow to the use of the dog teams was the appearance of snowmoniles.
By the mid 1960's most Alasknas didn't even
know the lditarod Trail existed, or that dos teens had played a crucial role in
Alaska's early settlements. Dorothy G.Page, a self-made historian, recognized
how few people knew about the former use of sled dogs as working animals and
about the Iditarod Trail's role in Alaska's colorful history. To she came up
with the idea to have a god sled race over the Iditarod Trail. She presented
her idea to an enthusiastic musher, as dog sled drivers are known, named Joe
Redington, Sr. Soon the pages and the Redintons were working together to
promote the idea of the Iditarod race.
Many people worked to make
the first Iditarod Trail Sled Dog Race a reality in 1967. The Aurora Dog
Mushers Club, along with men from the Adult Camp in Sutton, helped clear years
of overgrowth from the first nine miles of the Iditarod Trail. To raise
interest in the race, a $25,000 purse was offered, with Joe Redington donating
one acre of his land to help raise the funds. The short race, approximately 27
miles long, was put on a second time in 1969.
After these first two
successful races, the goal was to lengthen the race a little further to the
ghost town of Iditarod by 1973. However in 1972, the U.S. Army reopened the
trail as a winter exercise, and so in 1973, the decision was made to take the
race all the way to the city of Nome-over 1,000 miles. There were who believed
it could bot be done and that it wad crazy to send a bunch out into vast,
uninhabited Alaskan wilderness. But the race went! 22 mushers finished that
year, and to date over 400 people have completed it.

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:
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.
The man who talks of ‘duties’:
Arrowheads, which are ancient
hunting tools, are often themselves ‘hunted’ for their interesting value both
as artifacts and as art. Some of the oldest arrowheads in the United States
date back 12,000 years. They are not very difficult to find. You need only to
walk with downcast eyes in a field that has been recently tilled for the spring
planting season, and you might find one.
Arrowheads are tiny stones or pieces
of wood, bone, or metal which have been sharpened in order to create a tipped
weapon used in hunting. The material is honed to an edge, usually in a
triangular fashion, and is brought to a deadly tip. On the edge opposite the
tip is a flared tail. Though designs vary depending on the region, purpose, and
era of the arrowhead’s origin, the tails serve the same purpose. The tail of
the arrowhead is meant to be strapped onto a shaft, which is a straight wooden
piece such as a spear or an arrow. When combined, the arrowhead point and the
shaft become a lethal projectile weapon to be thrown by arm or shot with a bow
at prey.
Indian arrowheads are important
artifacts that give archeologists (scientists who study past human societies)
clues about the lives of Native Americans. By analyzing an arrowhead’s shape,
they can determine the advancement of tool technologies among certain Native
American groups. By determining the origin of the arrowhead material (bone,
rock, wood, or metal), they can trace the patterns of travel and trade of the
hunters. By examine the location of the arrowheads, archeologists can map out
hunting grounds and other social patterns.
Arrowheads are commonly found
along riverbanks or near creek beds because animals drawn to natural water sources
to sustain life were regularly found drinking along the banks. For this reason,
riverbeds were a prime hunting ground for the Native Americans. Now, dry and
active riverbeds are prime hunting grounds for arrowhead collectors.
Indian arrowheads are tiny pieces
of history that fit in the palm of your hand. They are diary entries in the
life of a hunter. They are museum pieces that hide in the dirt. They are
symbolic of the eternal struggle between life and death.
In the final
paragraph, the author writes, “They are museum pieces symbolic of the eternal
struggle between life and death.” Which of the following is the best way to
combine these two sentences, while keeping their original meaning?
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.

According to the passage, the question of abortion is
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?
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.
According to the passage, the Nancy
Drew mystery series was introduced in
Many people like to eat pizza, but
not everyone knows knows how to make it. Making the perfect pizza can be complicated,
but there are lots of ways for you to make basic version at home.
When you make pizza, you must
begin with the crust. The crust can be hard to make. If you want to make the
crust yourself, you will have to make dough using flour, water, and yeast. You
will have to knead the dough with your hands. If you do not have enough time to
do this, you can use a prepared crust that you buy from the store.
After you have chosen your crust,
you must then add the sauce. Making your own sauce from scratch can take a long
time. You have to buy tomatoes, peel them, and then cook them with spices. If
this sounds like too much work, you can also purchase jarred sauce from the
store. Many jarred sauces taste almost as good as the kind you make at home.
Now that you have your crust and
your sauce, you need to add the cheese. Cheese comes from milk, which comes
from cows. Do you have a cow in your backyard? Do you how to milk the cow? Do
you know how to turn that milk into cheese? If not, you might want to buy
cheese from the grocery store instead of making it yourself. When you have the
crust, sauce, and cheese ready, you can add other toppings. Some people like to
put meat on their pizza, while other people like to add vegetables. Some people
even like to add pineapple! The best part of making a pizza at home is that you
can customize it by adding your own favorite ingredients
