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.

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.

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.

B is right. If hospital subjects are conservative than general public that means they the general public will underestimate the effects by higher % time...thus it strengthens...

A, C and D are out of scope.

E weakens it.

(A) (C) has nothing to do with the premise.
(D) abilities that do not play an important role in driving safely also
has nothing to do with the premise.
(E) awareness of the advertisement also has nothing to do with
whether people underestimate the time to regain driving ability.

Thus I choose (B)

Answer choice B, thought process:

If even people in a hospital, study setting overestimate their abilities, then the general population is even more prone to making the same mistake.
Hence, the general population is quite likely to underestimate the time they have to wait after alcohol consumption until they can safely drive again, thus answer choice B strengthens the conclusion of the argument significantly.

Best regards,
Chris

" underestimated the time necessary to regain their driving ability."- does this mean they estimated time less than the actual time needed to regain?

what does "more conservatively" mean in this context?

how does B strengthen the argument?

Yes, exactly.

mallya12 wrote:

In this context, "more conservatively" means that, in estimating the time needed to regain their driving ability, people were more cautious in making their estimates than they would have been in a non-hospital setting, and thus arrived at estimates that were higher than they would have made in a non-hospital setting.

mallya12 wrote:

(B)strengthens the argument by directly stating an unstated assumption, that, like people in hospital settings, people not in hospital settings also underestimate the time needed to regain their driving ability. In other words, it confirms that the sample, people in hospital settings, is sufficiently representative of people in general for supporting the conclusion.

Also, (B) adds support for the conclusion by showing that the discrepancy between estimated time needed to regain driving abilities and actual time needed is in most cases even greater than that used to support the conclusion originally.

here is what I understand from the conclusion:

p1: A adv suggest people if they have consumed alcohol not to drive until they can do it safely.

p2: In hospital study, subjects who consumed alcohol when questioned estimated time less than the actual time needed to regain.

conclusion: This result indicates that many people who drink before driving will have difficulty following the advertisement's advice. Doubt How does the author make this conclusion? ( I didn't understand how did the author conclude this)

In answer choice B:

But in the premise, they have mentioned the subjects have underestimated(estimated time less than the actual time) the time. Whereas Answer choice B tells subjects are estimating higher . Please solve the confusion.

The truth is that how the author arrives at that conclusion is not quite clear, as there is a difference between estimating the time needed and waiting to drive until one can drive safely. So, we have to be a little creative maybe, and decide that the author is saying that people will have difficulty following the advice because they will have to wait longer than they estimate they will have to wait.

The passage says that, in a hospital setting, people underestimate the time needed to regain their driving ability.

Choice (B) does not contradict what the passage says.

What choice (B) indicates is that people in a hospital setting arrive at estimates higher than the estimates the people would arrive at were the people not in a hospital setting. All the same, we know from the passage that, even given what (B) says, the estimates made by people in hospital setting are STILL TOO LOW.

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.
