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 obvisouly be moreeffective in preventing collisions in those countries. In fact, the only countries that actually have such laws arefarther from the equator than is the continental United States.
Which of the following conclusions could be most properly drawn from the information given above?
-
ADrivers in the continental United States who used their headlines during the day would be just as likely to become involved in a collision as would drivers who did not use their headlights.

CThe 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.
