CR Questions September - 25 :Q1. Some doctors believe that a certain drug reduces the duration of episodes of vertigo, claiming that the average duration of vertigo for people who suffer from it has decreased since the drug was introduced.

Thus, we can conclude that the drug has no effect on the duration of vertigo.

(A) If a drug made a difference in the duration of vertigo, a three-month shortage of that drug would have caused a significant change in the average duration of vertigo.
(B) If there were any change in the average duration of vertigo since the introduction of the drug, it would have demonstrated that the drug has an effect on the duration of vertigo.
(C) A period of time greater than three months would not have been better to use in judging whether the drug has an effect on the duration of vertigo.
(D) Changes in diet and smoking habits are not responsible for any change in the average duration of vertigo since the introduction of the drug.

Q2. Sometimes it is advisable for a medical patient to seek a second opinion.

(A) Because of the awkwardness involved, it is best for patients not to seek second opinions unless it is absolutely necessary.
(B) In cases in which second opinions are necessary, the first physician often feels that his or her professional judgment is called into question.
(C) The process of obtaining a second medical opinion can be awkward for those involved.
(D) Physicians who are called upon to offer second opinions are always uncomfortable about evaluating the work of colleagues.
(E) In many cases in which medical patients seek second opinions, they are concerned about offending the first physician.
