### 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'.
