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.

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．

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．

OG给出的答案是E，个人觉得这个reasoning有问题，题干中明明说law在离equator远的国家更effective，为什么在reasoning中又说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．难道the continantal US是属于离equator近的国家吗？

遇到这种比较就会晕，没办法！求教各位NN!

第一句话：美国要白天也开灯，以免交通事故

第二句话：转折，这些法律在远离赤道的国家可能有用，因为白天光线少

第三句话：事实上，实施这些法律的国家，仅仅是那些远离赤道的国家

问conclusion

E：美国实施这法律和远离赤道的国家的实施这法律比起来，避免车祸效果差。

再来尝试translation

白天使用头灯的法律有利于防止撞车，但是，在离赤道越远的国家，白天的可见度越差，所以在这些国家这样的法律会更有效。事实上，离赤道远的国家，只有美国有这项法律。

E：白天使用头灯的法律的实施在美国没有比在其他国家有效。

我的理解是,此题中的in the countries that have the laws，应该不是远离赤道的国家，因为题干中的最后一句话说美国是唯一远离赤道而有这项法律的国家。如果这样看来，应该没有一个是正确答案。

In fact，the only countries that actually have such laws are farther from the equator than is the continental United States

这个句子你理解成“事实上，离赤道远的国家，只有美国有这项法律。”？

这里的结构是countries。。。 are farther from the equator than is the continental United States

即这些国家离赤道比美国远，这些国家是什么国家呢，有这样法律的国家。

对句子的理解出现偏差。
