QUESTION: 145

Although the new cochleae manufactured by Medotech will cost more than twice as much as the cochlear implants now in use, Medotech implants should still be cost-effective. Not only will surgery and recovery time be reduced, but Medotech cochlear replacements should last longer, thereby reducing the need for further hospital stays.
Which of the following must be studied in order to evaluate the argument presented above?

The amount of time a patient spends in surgery versus the amount of time spent recovering from surgery.
The amount by which the cost of producing Medotech cochlear replacements has declined with the introduction of the new technique for producing them.
The degree to which the use of Medotech cochlear replacements is likely to reduce the need for repeat surgery when compared with the use of the replacements now in use.
The degree to which the use of Medotech replacements are more carefully manufactured than are the replacements now in use,
The amount by which Medotech will drop in cost as the production procedures become standardized and applicable on a larger scale.

Answer(s): C

Explanation:

The best answer is C. To evaluate the argument it must be determined whether these savings will compensate for the increased cost. Therefore, study of the expected reduction in the need for further hospital stays is needed.

QUESTION: 146

Clarinet reeds often lose their freshness – become less responsive – after a few weeks of intense use. One clarinetist has hypothesized that a buildup of oil, rather than changes in the material properties of the reed, were responsible.

Which of the following investigations is most likely to yield significant information that would help to evaluate the hypothesis?

Determining what kind of wood is used to make the reeds used by jazz clarinetists.
Determining whether jazz clarinetists make their reeds lose their freshness faster than do classical clarinetists.
Determining whether identical lengths of reeds, of the same thickness, lose their freshness at different rates when put onto various brands of clarinets.
Determining whether rubbing various substances on the new reed causes them to lose their freshness.
Determining whether a fresh reed and one that has lost its freshness produce different qualities of sound

Answer(s): D

Explanation:

The best answer is D. The hypothesis has two parts: first, that intense use does not bring material changes that cause the reed to lose its freshness and, second, that oil causes the phenomenon. The experiment suggested in choice D directly test this hypothesis by contaminating strings that are known to have their original material properties.

QUESTION: 147

Many people claim that advertisements of alcoholic drinks influence young people to start drinking socially. In Iceland, however, where there has been a ban on the advertisement of alcoholic beverages since 1982, drinking is at least as prevalent among young people as it is in countries that do not have a similar ban.

Which of the following statements draws the most reliable conclusion from the information above?

Advertising does not play a role in causing young people to start or continue drinking.
Advertisements of alcoholic drinks cannot be the only factor that affects the prevalence of drinking among young people.
Banning advertisements of alcoholic drinks does not reduce the consumption of alcoholic drinks.
More youths drink if they are not exposed to advertisements of alcoholic drinks than if they are.
Most youths who drank in 1982 did not stop when the ban on advertisements of alcoholic drinks was implemented.

Answer(s): B

Explanation:

The best answer is B. If advertisements of alcoholic drinks were the only factor that affected young people’s drinking habits, there would be a difference in the prevalence of drinking between countries that ban such advertising and those that do not. According to the passage, there is no difference, so advertisements of alcoholic drinks cannot be the only factor.

Wheat and oats have the same nutritional value.
Rye has more nutritional value than oats.
Rye has more nutritional value than rice.
Rye and oats have the same nutritional value.
Oats have more nutritional value than wheat

Answer(s): B

Explanation:

The best answer is E. The question asks for a different premise that does not make the argument logically correct. Choice A leaves open the possibility that the conclusion of the argument is false.
