CAT Exam Analytical Reasoning Sample Questions

Analytical Reasoning Sample Questions

  1. 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?

    1. The word 'bald' can be translated into other languages.
    2. A word can have more than one meaning.
    3. A word such as 'monkey' can be applied to several animals that differ in some respects.
    4. Words can lack precision without being meaningless.
    5. People cannot think clearly without using words.

  2. 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?

    1. A shift by the gnats from drought areas to a normal area occupied by them
    2. The resultant stress from defoliation of trees attacked by the gnats for the second consecutive year.
    3. Attacks on the larvae by all kinds by parasitic wasps and flies.
    4. Starvation of the gnat larvae due to over population.
    5. Spraying of gnat infested areas with laboratory - raised Virus M.

        7. 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?

          1. Enough dust has been sent into the atmosphere by modern volcanic explosions to change the color of sunsets around the world for several years.
          2. Craters formed by heavenly bodies are plentiful in several areas of the South west where many dinosaur fossils have also been found.
          3. Studies conducted recently on the bone structure of dinosaurs show that they were very agile and not ponderous awkward animals as popularly believed.
          4. 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.
          5. Many meat-and plant-eating species of mammals who coexisted with the dinosaurs continue to exist today, although with a slightly modified appearance.

          1. Authorities concerned with mass transport in metropolitan cities are struggling with deficits. Commuters complain about delays and breakdowns, cuts in service, and fares higher than they are accustomed to paying. For all these reasons and because the price of fuel is still not prohibitive, the number of commuters using public transportation has fallen, adding to the deficits.

          2. Pharmaceutical firms are now engaged in the production of analogues of endorphins, peptides, which are thought to transmit messages among brain cells, which bring about pain relief. The pharmaceutical firms claim that the analogues, when injected into the bloodstream, will lead to effective and long-lasting pain relief by increasing the action of peptides already present in the brain.

          3. Quite often it happens that a particular crisis or opportunity induces people to find a practical use for things, which originally had no serious purpose. To exemplify this principle, consider dolls and mannequins, programmed to move and built for the delight of the wealthy in the eighteenth century; these were the forerunners of the modern computer. Similarly, it is almost certain that pets were the first domesticated animals. Domestication of animals seems to have arisen as an amusement long before it had any practical application.
