请教OG11VR-44, 看了解释更不明白？

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 fact，the only countries that actually have such laws are farther from the equator than is the continental United States.  这句话难道不是翻译为：事实上，美国是唯一一个在远离赤道的国家中实行（白天开头灯）法律的国家。

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．在美国实行日间开头灯法律来防止车辆相撞的有效性可能比那些有些相同法律的国家要小。请问这里的countries that have the laws是指那些国家，又从那里获得如此信息？

Argument Construction

Situation Laws requiring the use of headlights during the daytime are more effective at preventing car collisions in countries with 10wer daylight visibility, that is，in countries at greater distances from the equator．The only countries having these laws are those located farther from the equator than is the continental U．S．

Reasoning What conclusion can be drawn from this information? Countries with daytime headlight laws are all farther from the equator than is the continental US．The location is significant because daytime visibility is worse in those countries than it is in the continental U．S．How effective a；preventing collisions would such laws be in the continental United States with its greater proximity to the equator? It is reasonable to conclude that such laws would be less effective at preventing collisions there than they are in the countries farther from the equator．

答案是E.

这道题目很明显ETS的出题思路是说因为近赤道的国家的日间能见度要比远离赤道的国家（北美大陆）的能见度高，所以白天开车灯的法令在离赤道近的国家没有比在北美大陆（远离赤道的国家）有效防止撞车事件。我的问题是，如果我的理解正确的话，E的解释不是正好和解题思路相反？到底我那里理解错了？

Sudan, Kenya and Egypt are the
only countries I have been able to find where a country administers territory
on the other side of a boundary line where they technically have no sovereignty.

我的理解

题目讲的是  事故是由于能见度的问题   然后说离赤道越远能见度越差  最后说了美国离赤道的距离比那些颁布了法令的国家离赤道的距离近

所以综合考虑   要是美国实施了法令  能见度的提升肯定比那些之前的国家少  所以效果就要差一些    就是E
