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 fact, the only countries that actually have

such laws are farther from the equator than is the

continental 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 have

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.
