Quote:
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.
Conclusion: Many people who drink before driving will have difficulty following the advice that people who have consumed alcohol should not drive until they can do so safely.
The Author derived her conclusion about
most people based on a hospital study involving just
few people. If we can bridge this gap, we can strengthen the argument.
Which of the following, if true, most strongly supports the argument above?
Quote:
(A) Many people, if they plan to drink alcohol, make arrangements beforehand for a nondrinker to drive them home.
Making arrangements before hand is out of scope. Argument is regarding whether people who drink before driving will follow the advice.
Quote:
(B) The subjects in the hospital study generally rated their abilities more conservatively than would people drinking alcohol outside a hospital setting.
This option shows a connection between the people from the study and the rest of the people. It says that people from the study rated the time required to regain their ability to drive on a higher and safer side whereas in reality people probably would not wait that long. Hence, most people will have difficulty following the advice.
Quote:
(C) Some people refrain from drinking if they will have to drive to get home afterward.
Again, out of scope.The argument is regarding whether most people will wait long enough after drinking to regain their driving ability.Some people choosing to not drink at all will not effect the argument.
Quote:
(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.
This option is somewhat twisted and it will have no bearing on conclusion. The subjects in the hospital
only were questioned about the time necessary to regain abilities and this indeed plays an important role in driving safely.
Quote:
(E) Awareness of the public-service advertisement is higher among the general population than it was among the subjects in the hospital study.
If awareness of the public-service advertisement is higher among the general population than it was among the subjects in the hospital study, then most people will not have difficulty following the device. This can be a weakner if there exists causal relationship between awareness and people following the advice.
