A public-service advertisement advises that people who have consumed alcohol should not drive until they can do so safely. In a hospital study, however, subjects questioned immediately after they consumed alcohol underestimated the time necessary to regain their driving ability. This result indicates that many people who drink before driving will have difficulty following the advertisementâ€™s advice.

Which of the following, if true, most strongly supports the argument above?

(A) Many people, if they plan to drink alcohol, make arrangements beforehand for a nondrinker to drive them home.
(B) The subjects in the hospital study generally rated their abilities more conservatively than would people drinking alcohol outside a hospital setting.
(C) Some people refrain from drinking if they will have to drive to get home afterward.
(D) The subjects in the hospital study were also questioned about the time necessary to regain abilities that do not play an important role in driving safely.
(E) Awareness of the public-service advertisement is higher among the general population than it was among the subjects in the hospital study.

its B)...when the ppl in the hospital are more conservatively but admit that they wouldn`t follow the advice then the ppl outside the hospital, who are not so conservatively, are even more detained from the advice.

go B go...

If the 'conservatives' in the study underestimate the time, the actual non-conservative subjects would underestimate it even more...not a good sign..

IMO, "more conservatively" here means " more exactly" ...so even the subjects questioned, with more accurate rating of their ability, underestimated/ unaccurately estimated their ability ----> drinkers outside hospital setting rate their ability even less accurately ---> this supports the conclusion.B it is.

+1 D.
IMO, it is following a sequence. the chemicals should be put through rigorous testing. once the chemical is proved to be effective then it can no longer be patented.
