[問題]Verbal Review 44

44.

Laws requiring the use of headlights during daylight hours can prevent automobile collisions. However, since daylight visibility is worse in countries farther from the equator, any such laws would obviously be more effective in preventing collisions in those countries. In dact, the only countries that actually have such laws are farther from the equator than is the continaental United States.

Which of the following conclusions could be most properly drawn from the information given above?

(A) Drivers in the continental United States who used their headlights during the day would be just as likely to become involved in a collision as would drivers who did not use their headlights.

(B) In many countries that are farther from the equator than is the continental United States poor daylight visibility is the single most important factor in automobile collisions.

(C) The proportion of automobile collisions that occur in the daytime is greater in the continental United States than in the countries that ahve daytime headlight laws.

(D) Fewer automobile collisions probably occur each year in countries that have daytime headlight laws than occur within the continental United States.

(E) Daytime headlight laws would probably do less to prevent automobile collisions in the continental United States than they do in the countries that have the laws.

Answer: E

因為題目說離赤道較遠的國家(ex:芬蘭、挪威)白天視線不好，所以白天開車燈的規定在這些國家比在美國有效，所以這個規定在美國應該比較無助於防止意外發生囉。因此選E
