The recently injured athlete's drug test was positive for marijuana. Although the athlete insisted that he had not used the drug, he did admit to spending some time at a party where others were smoking. The doctor, however, insisted that contact of that sort could not result in a positive indicator.
Which of the following, if true, would contribute most to an explanation of the results of the drug test?
(A) Taking large amounts of inuprofen can result in false positives for marijuana.
(B) Secondhand smoke exposes innocent bystanders to a variety of toxic chemicals.
(C) Excessive exercise has been found to mask certain effects of marijuana use.
(D) The athlete had tested positive for amphetamines three years earlier.
(E) The team doctor sends all test samples out to an independent laboratory.

Fact : The recently injured athlete's drug test was positive for marijuana
Athlete's reasoning : spending some time at a party where others were smoking
Doctor's conclusion : contact of that sort could not result in a positive indicator.
Thus taking all these together the reason has to be something which has been administered to him because of his injury
(A) Taking large amounts of ibuprofen can result in false positives for marijuana. - Correct as gives alternate reason for his positive result
(B) Secondhand smoke exposes innocent bystanders to a variety of toxic chemicals. - Incorrect - toxic chemical ---- not marijuana
(C) Excessive exercise has been found to mask certain effects of marijuana use. - Irrelevant
(D) The athlete had tested positive for amphetamines three years earlier. - incorrect --- the question pertains to present testing
(E) The team doctor sends all test samples out to an independent laboratory. -- Irrelevant as veracity of tests are not being questioned
IMO A
