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.
Conclusion: The manufacturer thus concluded that reducing side effects was not the customers' primary consideration. It can be weakened by mentioning that reduction of side effect was the only primary consideration of the customers.
Reasoning of the premises may be are as follows,
What if the new diuretic is having too much cost than earlier one.
What if the new diuretic is far more efficient than the old one.
Such consideration weakens the manufacturer's conclusion regarding primary considerations of customers.
Which of the following, if true, would most seriously weaken the manufacturers conclusion?
A. Both hospitals and patients buy diuretics from this pharmaceutical company. - Irrelevant
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. - If new diuretic poses more risk to the safety of the patient than the old one, then many customers opted for the old one rather than new one. Old diuretic is more safer than the new one, indicating the customers are considering safety as the primary reason So, it weakens the conclusion.
C. Many customers of this pharmaceutical company also bought medications from companies who did not produce new diuretics reported to cause fewer side effects.- So what?
D. The newer diuretic can be used by all the patients who could use the earlier diuretic. - so what? irrelevant.
E. There was no significant difference in price between the newer diuretic and the earlier diuretic. - If there no difference in price, then customers could have bought the new one as it's having fewer side effects. But, it's out of context.
