CR 1000 T2 Q14

by neha.patni » Wed Jun 30, 2010 11:49 pm
A recent survey of all auto accident victims in Dole County found that, of the severely injured drivers and front-seat passengers, 80 percent were not wearing seat belts at the time of their accidents. This indicates that, by wearing seat belts, drivers and front-seat passengers can greatly reduce their risk of being severely injured if they are in an auto accident.
The conclusion above is not properly drawn unless which of the following is true?

(A) Of all the drivers and front-seat passengers in the survey, more than 20 percent were wearing seat belts at the time of their accidents.
(B) Considerably more than 20 percent of drivers and front-seat passengers in Dole County always wear seat belts when traveling by car.
(C) More drivers and front-seat passengers in the survey than rear-seat passengers were very severely injured.
(D) More than half of the drivers and front-seat passengers in the survey were not wearing seat belts at the time of their accidents.
(E) Most of the auto accidents reported to police in Dole County do not involve any serious injury.

OA A

(B) Considerably more than 20 percent of drivers and front-seat passengers in Dole County always wear seat belts when traveling by car.
We should talk only about drivers and front-seat passengers in the survey
and not about drivers and front-seat passengers in Dole County in general
(C) More drivers and front-seat passengers in the survey than rear-seat passengers were very severely injured.
No need to bring the rear-seat passengers in between
(E) Most of the auto accidents reported to police in Dole County do not involve any serious injury.
irrelevant

Narrows down to A / D .
How to reject between A / D ?

I took more than 5 minutes to solve this problem. I am not sure why A is correct, but we can eliminate other options.

B. Just a statement no use
C. 'rear-seat passengers' not mentioned in passage
D. Percentage vs actual number
E. We don't care about this.

Very tough problem. Answer is A
