The summarized version of this prompt is as follows:
few options (of lifestyle modification) ----> more likely to adhere (to the doctors advice)
Which one of the following most accurately expresses the principle illustrated above?
(A)
People are especially likely to ignore the advice they get from doctors if they are confused about that advice. - The passage does not mention anything about people getting 'confused'. Besides, the passage discusses the 'likelihood' of adherence, not 'confusion'. Hence, we can
eliminate (A). (B)
People dislike calculating the best of a variety of choices unless they can see a clear difference among the benefits that would result from each choice. - The passage does not mention any sort of calculation regarding the benefits, let alone the 'difference' among the available options. Hence,
eliminate (B).(C)
The tendency people have to alter their behavior varies inversely with the number of alternatives available to them for behavior modification. - This is exactly what we have in the passage. Hence,
(C) is the right answer choice.
(D)
Most people are unlikely to follow their doctor’s advice unless they can vividly imagine the consequences of not following the advice. - The passage does not imply anything about what would happen if people 'do not' follow the doctor's advice. Hence, we can
eliminate (D).(E)
In getting good results, the clarity with which a doctor instructs a patient is of equal importance to the accuracy of the doctor’s diagnosis on which that instruction is based. - the passage never makes any distinction between the clarity and accuracy of the doctor's diagnosis. hence, we can
eliminate (E).If you find this explanation helpful, please do give it a kudos
