Physician: The patient is suffering either from disease X or else from disease Y. but there is no available test for distinguishing X from Y. Therefore, since there is an effective treatment for Y but no treatment for X, we must act on the assumption that the patient has a case of Y.

The physicianâ€™s reasoning could be based on which one of the following principles?

(A) In treating a patient who has one or the other of two diseases, it is more important to treat the diseases than to determine which of the two diseases the patient has.

(B) If circumstances beyond a decision makerâ€™s control will affect the outcome of the decision makerâ€™s actions, the decision maker must assume that circumstances are unfavorable

(C) When the soundness of a strategy depends on the truth of a certain assumption, and the first step in putting the strategy into effect must be to test the truth of this assumption.

(D) When success is possible only if a circumstance beyond oneâ€™s control is favorable, and then oneâ€™s strategy must be based on the assumption that this circumstance is in fact favorable

(E) When only one strategy carries the possibility of success. Circumstances must as much as possible be changed to fit this strategy.

Try to parallel the question and Principal:

Question:
1. there is no available test for distinguishing X from Y (Thing beyond ur control)
2. Treatment will be successful only when disease is Y.
1 & 2 together says that: success is possible only when if a circumstance beyond one's control is favourable.
3. So u should assume that it is infact Y. i.e. ur stategy assumes that the condition is favourable.

Am I making sense to you ?

E too comes close but the portion " changed to fit the circumstances" dosn't go well .

agree, I was between D and E, but E seems too strong, so D is my pick.
