In marketing their products, drug companies often send gifts to physicians. According to a recent survey, most physicians believe that their own choices when prescribing drugs are not influenced by drug companies' gifts. The same survey indicates that the majority of physicians believe that most other physicians prescription choices are influenced by such gifts.
If the survey results are accurate, which one of the following must be true?
(A) Physicians who do not accept gifts from drug companies are less likely to prescribe unnecessary drugs than those who do accept such gifts.
(B) Most physicians believe that drug companies should adopt new guidelines that regulate their practices in sending gifts to physicians.
(C) Some physicians are mistaken either about the degree to which they are influenced by gifts from drug companies or about the degree to which such gifts influence other physicians.
(D) Some physicians who admit that their own choices when prescribing drugs are influenced by drug companies' gifts believe that other physicians prescription choices are influenced to a greater degree by such gifts.
(E) All physicians who admit that their own choices when prescribing drugs are influenced by drug companies gifts believe that most other physicians' prescription choices are also influenced by such gifts.

The same survey indicates that the majority of physicians believe that most other physicians prescription choices are influenced by such gifts.
If the survey results are accurate, which one of the following must be true?
The key point is that most physicians say “I am not influenced,” but at the same time most physicians say “other physicians are influenced”. Those two beliefs cannot all be correct together, so at least some physicians must be mistaken somewhere.
(A) Physicians who do not accept gifts from drug companies are less likely to prescribe unnecessary drugs than those who do accept such gifts.
The survey says nothing about unnecessary drugs or about comparing physicians who accept gifts with those who do not.
(B) Most physicians believe that drug companies should adopt new guidelines that regulate their practices in sending gifts to physicians.
The survey gives no information about what physicians think drug companies should do.
(C) Some physicians are mistaken either about the degree to which they are influenced by gifts from drug companies or about the degree to which such gifts influence other physicians.
This is the best answer. If most physicians think they themselves are not influenced, but most also think other physicians are influenced, then at least some of these judgments must be wrong. The two majority beliefs cannot all be accurate at once.
(D) Some physicians who admit that their own choices when prescribing drugs are influenced by drug companies' gifts believe that other physicians prescription choices are influenced to a greater degree by such gifts.
This could be true, but it does not have to be true. The survey does not tell us that any such physicians exist.
(E) All physicians who admit that their own choices when prescribing drugs are influenced by drug companies gifts believe that most other physicians' prescription choices are also influenced by such gifts.
This is much too strong. The survey gives no basis for such an “all” claim.
