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.
Which of the following literary
techniques does the author use in the passage?
I hyperbole, characterized by the
use of exaggeration for effect
II foreshadowing, characterized by
the use of hints that depict future events in the narrative or story
III flashback, characterized by
the description of a scene set in a time earlier than the main story
The
history of civilization shows how man always has to choose between making the
right and wrong use of the discoveries 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 recognized 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 were 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 its quality. Fields of the work of science

Democratic societies from the earliest times have expected
their governments to protect the weak against the strong. No ‘era of good
feeling’ can justify discharging the police force or giving up the idea of
public control over concentrated private wealth. On the other hand, it is
obvious that a spirit of self – denial and moderation on the part of those who
hold economic power will greatly soften the demand for absolute equality. Men
are more interested in freedom and security than in an equal distribution of
wealth. The extent to which Government must interfere with business, therefore,
is not exactly measured by the extent to which economic power is concentrated
into a few hands. The required degree of government interference depends mainly
on whether economic powers are oppressively used, and on the necessity of
keeping economic factors in a tolerable state of balance.
However, with the necessity of meeting all these dangers and
threats to liberty, the powers of government are unavoidably increased,
whichever political party may be in office. The growth of government is a
necessary result of the growth of technology and of the problems that go with
the use of machines and science. Since the government in our nation, must take
on more powers to meet its problems, there is no way to preserve freedom except
by making democracy more powerful.
The advent of science and technology has increase the
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.
Which of the following is
not true in context of the given passage?
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.

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.
If something is designated, it is
A great deal of discussion countries as to the real extent
of global environmental degradation and its implicational. What few people
challenge however is that the renewable natural resources of developing
countries are today subject to stresses of unprecedented magnitude. These
pressures are bought about, in part, by increased population and the quest for
an ever expanding food supply. Because the healthy, nutrition and general
well-being of the poor majority are directly depends on the integrity and
productivity of their natural resources, the capability of governments to manage
them effectively over the long term becomes of paramount importance.
Developing countries are becoming more aware of the ways in
which present and future economic development must build upon a sound and
sustainable natural resources base. Some are looking at our long tradition in
environmental protection and are receptive to US assistance which recognizes
the uniqueness of the social and ecological systems in these tropical
countries. Developing countries recognize the need to improve their capability
to analyze issues and their own natural resource management. In February 1981,
for example AID funded a national Academy of Sciences panel to advise Nepal on
their severe natural resource degradation problems. Some countries such as
Senegal, India, Indonesia and Thailand, are now including conservation concerns
in their economic development planning process.
Because so many governments of developing nations have
recognized the importance of these issues, the need today is not merely one of
raising additional consciousness, but for carefully designed and sharply
focused activities aimed at management regimes that are essential to the
achievement of sustained development.
Some of the developing countries of Asia and Africa have
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.

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.

Which of the following thinks that the individual
is in debt to the society?
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 beginning of the story, which is the best
definition for ‘captivated’?
