CR 1

The proposal requiring mutual fund companies to set aside a part of their fee for investor education is laudable but meaningless. The challenge actually lies in finding the right ways of educating investors and making them financially literate.

Which of the following, if true, most strongly supports the argument?

(A) People looking to invest in mutual funds currently lack the knowledge to make informed decisions.

(B) Most mutual funds have accumulated large reserves of cash for investor education.

(C) Investing in mutual funds is very different from investing in other financial instruments such as shares and debentures.

(D) Financially literate customers, on the whole, provide more business to mutual fund companies than do financially ignorant ones.

(E) Activities aimed at educating customers cost a lot of money and most mutual funds do not have the cash reserves to conduct such activities.

____________________________________
CR 2

There should be a ban on television commercials for prescription drugs. These commercials put preconceived notions in people’s heads and make them ask their doctor for a drug whose side effects they are not aware of. If a person needed that drug, their doctor would have already prescribed it to them.

If the statements above are true, which of the following must be true?

(A) Most people who visit a doctor are already aware as to which drug the doctor will most likely prescribe to them.

(B) Television commercials for prescription drugs don’t have an educational aspect to them in that they don’t educate the consumers about the use of various drugs.

(C) Pharmaceutical companies try to sell harmful drugs to consumers by using deceptive advertising.

(D) At least some people ask doctors to recommend to them medicines whose advertisement they have seen on television.

(E) At times, doctors themselves use the advertisements for prescription drugs as a source of information to recommend medicines to their patients.

As pets have become increasingly humanized in recent years, almost becoming a substitute for children in some cases, owners have become increasingly concerned about the quality of their pets’ diets , leading to rising interest in grain-free offerings.

In the argument given, the two portions in boldface play which of the following roles?

(A) The first is the cause of a given effect; the second is a criticism of that effect.

(B) The first is the cause of a given effect; the second is the opinion of a group that provides further support for this effect.

(C) The first describes a general scenario and the second provides a specific implication of this scenario.

(D) The first is the point of view of a group of people and the second contradicts this point of view by providing conflicting evidence.

(E) The first is the conclusion of the argument and the second provides evidence on the basis of which this conclusion has been arrived at.

CR 2

People who drink coffee regularly say that they are addicted to caffeine because they feel that they can’t live without it. Addiction is defined as a state in which a person strongly depends on a drug with severe withdrawal symptoms. He should have an urge to consume it more and more and is tolerant to a particular dose. Based on this definition, caffeine consumption does not qualify as an addiction. Researches too have shown that caffeine does not cause any kind of addiction. Alcohol or other drug addiction can have severe social and physical consequences but this is not the case with caffeine which further strengthens the belief that it is not addictive or does not cause addiction.

In the argument given, the two portions in boldface play which of the following roles?

(A) The first provides the definition of a term that has been used to arrive at a conclusion; the second provides further support for that conclusion.

(B) The first provides the definition of a term; the second provides further support for that definition.

(C) The first provides a definition that constitutes the main premise of the argument; the second is the conclusion of the argument as a whole.

(D) The first and second are contradictory claims, both of which together provide support for the primary conclusion of the argument.

(E) The first provides evidence in support of the conclusion of the argument; the second provides further justification for this evidence.
