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?
Quote:
(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.
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
Quote:
(A) The speed limit alone is probably not responsible for the continued reduction in highway deaths in the years after 1974.
Left out and its correctly concluding that may be some other reasons are also possible.!- so click A and press Yes
Winner -A
