Have you ever wondered what keeps a hot air balloon flying? The same principal that keeps food frozen in the open chest freezers at the grocery store allows hot air balloons to fly. It's very basic principle: Hot air rises and cold air falls. So while the super-cooled air in the grocery store freezer settles down around the food , the hot air in a hot air in a hot air balloon pushes up, keeping the balloon floating above the ground. In order to understand more about how this principal works in hot air balloons, it helps to know more about hot air balloons themselves.A hot air balloon has three major parts: the basket, the burner, and the envelope. The basket is where passengers ride. The basket is usually made of wicker. This ensures that it will be comfortable and add little extra weight. The burner is positioned above the passenger's heads and produced a huge flame to heat the air inside the envelope. The envelope is the colorful fabric balloon that holds the hot air. When the air inside the envelop is heated, the balloon rises.The pilot can control the up-and-down movements of the hot air balloon by regulating the heat in the envelope. To ascend, the pilot heats the air in the envelope. When the pilot is ready to land, the air in the balloon is allowed to cool and the balloon becomes heavier than air. This make the balloon descend.Before the balloon is launched, the pilot knows which way the wind is blowing. This means that she has a general idea about which wau the balloon will go. But, sometimes the pilot can actually control the direction that the balloon flies while in flight. This is because the air above the ground is sectioned into layers in which the direction of the wind may be different. So even though the pilot can't steer the balloon, she can fly higher or lower into a different layer of air. Some days the difference between the directions of the wind between layers is negligible. But other days the difference is so strong that it can actually push the balloon in a completely different directionAs used in paragraph, which is the best antonym for 'descend'?

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.

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.

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?
|
A. Rickety, Neglected, Run-down
B. Ancient, Old, Primitive
C. Dejected, Crushed, Melancholy
D. Discarded, Abandoned, Discharged

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.
Which of the
following best summarizes the main idea of paragraph 3?
|
A. Archeologists can determine many things about Native American societies simply by looking at an arrowhead
B. Archeologists are scientists who study a range of events that have already occurred
C. Arrowheads represent the only way to determine how Native Americans lived in the past
D. Archeologists know so much about ancient societies because they have conducted extensive research about them

When Greg went to the giant aquarium near his house, he had one type of animal that he loved to watch. He liked dolphins and manatees, but he loved whales. Baluga whales from the arctic were really neat, but it was the Killer Whales especially that had his heart.For hours, from the park opening untill closing, he could watch them. Their black-and-white patterned skin reminded him of a tuxedo, a penguin,or even a zebra, but on the whales it seemed even more special. It made them stand out in the water.Their playfulness and intelligence amazed him, too. He liked to watch the trainers coax them through jumps,leaps, and other tricks. They talked and squawked at the trainers. One time the trainer even got launched into the air off the whale's nose. It was an impressive feat.It always surprised him now fast and agile such a massive creature could be. He always expected them to be slow and lumbering, but they were fast like a bullet, darting through their huge tanks and exploding from the water.In the park, they were fast like a bullet, darting through their huge tanks and exploding from the water.In the park, they ate fish and other snacks, and lots of them. In the wild, he understood why they had their fierce name. They could eat seals, sea lions, small whales, and just about anything they could catch. Their teeth were sharp and predatory. They were the top of the food chain - even more dangerous than sharks.The Killer Whales were amazing animals. They inspired him to learn more about the sea. He thought that some day he might want to be a marine biologist.Then, he could learn about his favourite animals as a job.For now, he'd have to settle for watching them through the tank's glass and reading about them. However, there was always the future. Question: Which of these is NOT a reason why Greg likes killer whales?
|
A. their speed and power
B. their colors
C. their slowness
D. their intelligence

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?
|
A. The policy gives a blue print for program of action
B. The woman should be given greater control of police stations
C. There is no law-enforcement bias in case of dowery
D. For effective implementation, the government agencies will have to order their priorities

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.
‘Era of good feeling’ in the paragraph refer to
|
A. Time of prosperity
B. Time of adversity
C. Time without government
D. Time of police atrocities
