Premise:During the first year that both were sold, the earlier medication far outsold the new one

conclusion;
the manufacturer thus concluded that reducing side effects was not the customers' primary consideration.

IMO B; weakens the conclusion ; Many customers consider older medications a better safety risk than new ones, since more is usually known about the safety of the earlier drugs.
A pharmaceutical company developed a new diuretic reported to cause fewer side effects than their old diuretic, which was still being manufactured. During the first year that both were sold, the earlier medication far outsold the new one; the manufacturer thus concluded that reducing side effects was not the customers' primary consideration.

Which of the following, if true, would most seriously weaken the manufacturers conclusion?

A. Both hospitals and patients buy diuretics from this pharmaceutical company.
B. Many customers consider older medications a better safety risk than new ones, since more is usually known about the safety of the earlier drugs.
C. Many customers of this pharmaceutical company also bought medications from companies who did not produce new diuretics reported to cause fewer side effects.
D. The newer diuretic can be used by all the patients who could use the earlier diuretic.
E. There was no significant difference in price between the newer diuretic and the earlier diuretic

Which of the following, if true, would most seriously weaken the manufacturers conclusion?

A. Both hospitals and patients buy diuretics from this pharmaceutical company. -- doesn't give any important detail
B. Many customers consider older medications a better safety risk than new ones, since more is usually known about the safety of the earlier drugs. -- the reason customers buy old medication more than new one is they trust in the old brand which is their primary consideration not the result of the sides effects. correct
C. Many customers of this pharmaceutical company also bought medications from companies who did not produce new diuretics reported to cause fewer side effects. -- strenghten
D. The newer diuretic can be used by all the patients who could use the earlier diuretic. -- kinda strenghten
E. There was no significant difference in price between the newer diuretic and the earlier diuretic. --out of scope

therefore, B

Any option that provides an alternate explanation of why older medication outsold the newer one even though newer medication has a clear benefit over the older medication or that reduces our belief in manufacturer's conclusion that reducing side effects was not the customers' primary consideration will weaken the argument.

Option B provides a reason for the difference in sale of the two types of medication, and therefore is the correct answer.

Other options do not impact the argument in the way required.

Competition Mode Question



A pharmaceutical company developed a new diuretic reported to cause fewer side effects than their old diuretic, which was still being manufactured. During the first year that both were sold, the earlier medication far outsold the new one; the manufacturer thus concluded that reducing side effects was not the customers' primary consideration.

Which of the following, if true, would most seriously weaken the manufacturers conclusion?

A. Both hospitals and patients buy diuretics from this pharmaceutical company.
B. Many customers consider older medications a better safety risk than new ones, since more is usually known about the safety of the earlier drugs.
C. Many customers of this pharmaceutical company also bought medications from companies who did not produce new diuretics reported to cause fewer side effects.
D. The newer diuretic can be used by all the patients who could use the earlier diuretic.
E. There was no significant difference in price between the newer diuretic and the earlier diuretic.

Official Explanation



Correct Answer: B

The manufactures conclusion was that reducing side effects was not the customers' primary consideration. Choice B states that customers consider older medication a better safety risk, so those customers bought the older diuretic out of safety considerations.
