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.

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.
According to the passage, fleas are
able to jump

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.
Which of the following is
most nearly the same in meaning to ‘callousness’ as used in the passage?
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
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.
Why did Linnaeus name the plant Theobroma?
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.

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.

As used in paragraph 2, which is
the best definition for esoteric?
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.
In 1925, when a diphtheria
outbreak threatened the lives of people in the remote town of Nome, the
government used the Iditarod Trail to transport medicine nearly 700 miles to
the town. If the author chose the include this fact is the passage, it would

The history of literature really began was the earliest of
the arts. Man danced for joy round his primitive camp fire after the defeat and
slaughter of his enemy. He yelled and shouted as he danced and gradually the
yells and shouts became coherent and caught the measure of the coherent and
caught the measure of the dance and thus the first war song was sung. As the
idea of God developed prayers were framed. The songs and prayers became
traditional and were repeated from one generation to another, each generation
adding something of its own. As man slowly grew more civilized, he was
compelled to invent some method of writing by three urgent necessities. There
were certain things that it was dangerous to forget and which, therefore, had
to be recorded. It was often necessary to communicate with person who were some
distance away and it was necessary to protect one’s property by making tools,
cattle and so on, in some distinctive manner. So man taught himself to write
and having learned to write purely for utilitarian reasons he used this new
method for preserving his war songs and his prayers. Of course, among these
ancient peoples, There were only a very few individuals who learned to write,
and only a few could read what was written.

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.
