Questions 46 - 47
The principal evil in today's society is selfishness. Everywhere we see people, who are concerned only with themselves. Personal advancement is the only motivating force in the world today. This does not mean that individuals are not willing to help one another; on the contrary, _________. But, these are only short-term occurrences which ultimately serve our long-term goal of personal gain.

we are always trying to undermine others’ endeavors.

It can be proved by an example that our words are devoid of meaning as they cannot be distinguished from their opposites. People think that they are aware of the difference between the meanings of 'bald' and 'having hair' Let us suppose that an average twenty-one year old has X strands of hair on his or her head. We say that such a person is not bald but has hair. But surely one hair less would make no difference, and a person with X - 1 hairs on his or her head would be said to have hair. Suppose we go on like this, decreasing one hair at a time, the result would be the same. Then what difference would there be between someone who has one hair and someone who has none? We call them both bald. Thus, we cannot make a distinction between the terms 'bald' and 'having hair.'
Among the following statements, which statement best counters the argument above?
The word 'bald' can be translated into other languages.
A word can have more than one meaning.
A word such as 'monkey' can be applied to several animals that differ in some respects.
Words can lack precision without being meaningless.
People cannot think clearly without using words.
Ans : D
Virus M helps in controlling the population of gnats; they manage to do this by killing the moth's larvae. Though the virus is always present in the larvae, it is only every six or seven years that the virus seriously decimates the numbers of larvae, greatly reducing the population of the gnats. Scientists are of the opinion that the gnats, usually latent, are activated only when the larvae experience biological stress.
In case the above mentioned scientists are correct, it can be inferred that the decimation of gnat populations by the virus M could be most probably activated by the following conditions?
A shift by the gnats from drought areas to a normal area occupied by them
The resultant stress from defoliation of trees attacked by the gnats for the second consecutive year.
Attacks on the larvae by all kinds by parasitic wasps and flies.
Starvation of the gnat larvae due to over population.
Spraying of gnat infested areas with laboratory - raised Virus M.
Ans : D

A survey recently conducted revealed that marriage is fattening. The survey found that on an average, women gained 23 pounds and men gained 18 pounds during 13 years of marriage. The answer to which among the following questions would be the most appropriate in evaluating the reasoning presented in the survey ?

Classical works occupy a unique and peculiar position. They are imperishable as cultural landmarks, but the views expressed in some of the works are often superseded by newer views. But the classics survive just like ancient castles, as imposing features of the landscape, yet unsuited for habitation unless remodeled.
The principal point put forth in the above passage is that classical works.
Demand our respect and admiration even if their ideas are no longer current.
Prove to be obstacles in the path of new ideas as they are unduly respected.
Should be preserved and treasured as scholarly opinion keeps changing and they will come into fashion again.
Lose their distinctive features as time passes.
Are not given due consideration by the younger generation.
Ans : A
Experts in the field of forestry are now questioning the policy of attempting to extinguish all forest fires instead of allowing them to run their course and die out on their own. The study of forest fires indicates that in the long run, forest fires may in fact, be beneficial to the ecology as a whole.
Among the following, which statement would logically follow from one of the ’observations’ referred to in the passage above ?
Most of the forest fires are causes due to natural reasons like lightning rather than as a result of human carelessness.
Every year the number of people dying as they attempt to fight forest fires is greater than the number of people who would have died or suffered injury if the fires were allowed to run their own course.
Accumulation of highly flammable dead brushwood and timber, which could lead to massive uncontrollable fires is prevented by frequent small forest fires.
The animal and plant life destroyed by forest fires seldom represents endangered species.
Studies indicate that forest fires regularly occurred in the times prior to human occupation of forest areas.
Ans : C
There is a theory that the dinosaurs inhabiting the earth were destroyed when a huge heavenly body hit the earth. The impact of the heavenly body when it struck the earth threw a mass of pulverized debris into the atmosphere. This dust created a fog, which blocked the sunlight depleting plant life. This resulted in the perishing of the plant-eating dinosaurs; the meat-eating dinosaurs, who preyed on the plant-eaters inturn starved to death.
Which among the following statements, would best support the above mentioned theory, if true?
Enough dust has been sent into the atmosphere by modern volcanic explosions to change the color of sunsets around the world for several years.
Craters formed by heavenly bodies are plentiful in several areas of the South west where many dinosaur fossils have also been found.
Studies conducted recently on the bone structure of dinosaurs show that they were very agile and not ponderous awkward animals as popularly believed.
The sedimentary rock strata of the earth formed from atmospheric dust at the time the dinosaurs disappeared contains minerals and other trace elements in proportions characteristic of the heavenly bodies.
Many meat-and plant-eating species of mammals who coexisted with the dinosaurs continue to exist today, although with a slightly modified appearance.
