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 advertisement'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.
Though I got the answer right by the process of elimination under 2 mins, I want to know what should be the reasoning applied to hit correct answer directly?

on the second reading of stimuli and then the answer choices from E to A i got the point - choice B worsens the condition stated by general population outside of hospital - the people in hospital rated their abilities more conservatively than those outside of hospital, thus the outside people will drink and drive before regaining their driving abilities even more frequently. Hence choice B should strengthen the argument of not following the add's advice

I go with B. Assume the people in the hospital say it takes three hours to begin to drive safely. Since they underestimate, the real time could be four hours. These people would start driving an hour too soon. People in bars, however, would be less conservative so they might estimate two hours. They would be back behind the wheel two hours too early. That makes it even more likely that people are on the road before they should be.
