### HideShow timer Statistics

1. 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.

Is it (A) ? I prefer A to E because I found E as an extreme wording speed limit cannot be responsible
Am I right>??

I go for A as well. As someone already stated, the wording in E is too strong.

Agree with A.. E is too extreme ( cannot be responsible)

The argument above expresses a causal connection between reduction in the speed limit and reduction in number of deaths even though the average speed of vehicles has increased.
Thus, to resolve above paradox, cause other than speed limit reduction can be there to reduce number of deaths.
Only A states the occurence of any other probable cause and thus is the best choice among others.

A for me as well.

E is extreme and also mention 'abrupt decline', which argument has no where mentioned. Argument says ' the number of deaths has continued to fall' which is different from 'abrupt decline'.

A too. E seems to extreme. And all the other ones were out of the scope of context.

Surprised. E directly contradicts the premise - 180 degree wrong choice ! Not extreme. Its wrong, its hopeless You are not allowed to question the premise.

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

At first I opted for E.
After going through the replies I am convinced that option A is correct. Thanks guys.
+1 for the above post.

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.

(A) The speed limit alone is probably not responsible for the continued reduction in highway deaths in the years after 1974. Best answer. B, C, and D could be some or the reasons why this happened, but nothing about the stem leads you to these specific reasons. All we know is some other factors were probably contributing to the decline in highway deaths.
(B) People have been driving less since 1974. May be true, but this is not a conclusion you can draw from the question stem.
(C) Driver-education courses have been more effective since 1974 in teaching drivers to drive safely. May be true, but this is not a conclusion you can draw from the question stem.
(D) In recent years highway patrols have been less effective in catching drivers who speed. May be true, but this is not a conclusion you can draw from the question stem.
(E) The change in the speed limit cannot be responsible for the abrupt decline in highway deaths in 1974. The stem does not mention other events occurring at the same time. So you can not eliminate the speed limit reduction as the cause of reduced highway deaths. As others have stated, too extreme.

E uses too strong words.. also the first statement says - 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.

this helps in eliminating 'E'

I chose A too. As noted by someone above, E is incorrect NOT because it has extreme wording(s) but because it contradicts the premise.

A is clearly right, but D can still be true, because in another question, D has the pattern of a correct answer.

Done, I have checked.
A is a common pattern in gmat for inference questions. D is also a common pattern for explain questions. Test takers should be aware of this.
