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 true regarding the reasons for
progress in genetic engineering?
Paul’s wife knows Paul loves to read cookbooks. She decides to
get him one for his birthday. Paul tells her he will try to make a new recipe
for three days in a row. On Monday, Paul makes blueberry pancakes for
breakfast. He gets the blueberries from the farmers’ market. On Tuesday, Paul
makes beef soup for dinner. He puts in cubes of beef, carrots, and onions. The
recipe calls for cream, but Paul does not cream. He uses water instead. On Wednesday,
Paul makes a tomato salad with cucumbers and onions. He picks the cucumbers and
tomatoes from his garden. He likes this dish best. It was also the easiest for
him to make.
Which dish was the easiest for Paul to make?
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 at the beginning of the story, which is the best antonym for ‘deteriorate’?
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.
Based on information in the
passage, the author most likely believes 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 are bacteria?
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 the main concern about the PDS?
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.
Based on the information in
paragraph 2, we can understand that
I male mosquitoes and female mosquitoes have different
eating habits
II male mosquitoes are harmless to
humans
III female mosquitoes are
responsible for transmitting disease to humans
