After the national speed limit of 55 miles per hour was imposed in 1974, the number of deaths per mile driven on a highway fell abruptly as a result. Since then, however, the average speed of vehicles on highways has risen, but the number of deaths per mile driven on a highway has continued to fall.

Which of the following conclusions can be properly drawn from the statements above?


(A) The speed limit alone is probably not responsible for the continued reduction in highway deaths in the years after 1974.

(B) People have been driving less since 1974.

(C) Driver-education courses have been more effective since 1974 in teaching drivers to drive safely.

(D) In recent years highway patrols have been less effective in catching drivers who speed.

(E) The change in the speed limit cannot be responsible for the abrupt decline in highway deaths in 1974.

IMO A

(A) The speed limit alone is probably not responsible for the continued reduction in highway deaths in the years after 1974.


(B) People have been driving less since 1974. There is no info about the trend in driving

(C) Driver-education courses have been more effective since 1974 in teaching drivers to drive safely.again no info about any friver-education courses

(D) In recent years highway patrols have been less effective in catching drivers who speed.This passage is about the trend in number of accidents no about people who speed

(E) The change in the speed limit cannot be responsible for the abrupt decline in highway deaths in 1974.It may or it may not be...we don't know that....extreme opinion

Here B,C,D are completely out of scope.-eliminate them

(E) The change in the speed limit cannot be responsible for the abrupt decline in highway deaths in 1974.
too strong and the argument has stated that after imposing speed limits the deaths started to decline. So imposing speed limits is also one of the evidences that deaths started to decline,But this option is telling against that.-so eliminate d

Left out and its correctly concluding that may be some other reasons are also possible.!- so click A and press Yes
Winner -A

The Argument is encompassing a period of 1971 and since then

Which of the following conclusions can be properly drawn from the statements above?


(A) The speed limit alone is probably not responsible for the continued reduction in highway deaths in the years after 1974.

(E) The change in the speed limit cannot be responsible for the abrupt decline in highway deaths in 1974.
This one is talking about only 1974 - As per the premise give ( first statement) - E is giving an incorrect conclusion. If we weigh only the first statement of the argument - we might well say that the change in speed limit indeed is responsible for reduction in high way deaths.

(A) The speed limit alone is probably not responsible for the continued reduction in highway deaths in the years after 1974.---- Could be the answer


(B) People have been driving less since 1974.--not mentioned anywhere.


(C) Driver-education courses have been more effective since 1974 in teaching drivers to drive safely.- Driver education? No mention again.

(D) In recent years highway patrols have been less effective in catching drivers who speed.- could be but cannot be inferred.

(E) The change in the speed limit cannot be responsible for the abrupt decline in highway deaths in 1974.- Extreme choice.
