【OG20-P571-640题】

Beginning in 1966 all new cars sold in Morodia were required to have safety belts and power steering. Previously, most cars in Morodia were without these features. Safety belts help to prevent injuries in collisions, and power steering helps to avoid collisions in the first place. But even though in 1966 one-seventh of the cars in Morodia were replaced with new cars, the number of car collisions and collision-related injuries did not decline.

Which of the following, if true about Morodia, most helps to explain why the number of collisions and collisions related injuries in Morodia failed to decline in 1966?

(A) Because of a driver education campaign, most drivers and passengers in cars that did have safety belts used them in 1966.

(B) Most of the new cars bought in 1966 were bought in the months of January and February.

(D) An excessive reliance on the new safety features led many owners of new cars to drive less cautiously in 1966 than before.

(E) The seat belts and power steering put into new cars sold m 1966 had to undergo strict quality control inspections by manufacturers, whether the cars were manufactured in Morodia or not.

答案：

情景：自

从1966年开始，所有的新车都装上了安全带和能量制动。这两个东西可以帮助防止碰撞和受伤。但，即便是1966年1/7的车已经装上了这两个东西，汽车碰撞和碰撞导致受伤依然没有降低。推理：提炼出前提和结论则有：前提：1966年1/7的车已经装上了这两个东西。结论：汽车碰撞和碰撞导致受伤“应该“降低。请注意，本题原文中前提和结论是矛盾的，所以问题让我们解释这个矛盾。因此，在进行推理分析时，需先把结论修正。削弱正常的推理关系，即可以解释原文中的矛盾。显然地，前提和结论应是因果关系，本题为因果推理。选题方式：答案选项需断掉因果之间的关系。选项分析： A选项：由于驾驶员教育活动，大部分的没有安全带的驾驶员和乘客在1966年也用上了安全带。我们要找的，是能断掉装安全带和受伤率降低的关系的选项，本选项智能说明用安全带的人多和少，与事故率无关。 B选项：大部分在1966年买的新车是在1月和2月买的。本选项和推理无关。 C选项：在1965年，1/7的车被换为了新车。本选项和推理无关。 D选项：Correct. 依靠新的安全特征让很多车主在1966年比之前开的更加放肆了。本选项直接断掉了因果的关系，即，虽然安全特征会让行驶更安全，但是开车的人心态变了，自然可以影响事故率。 E选项：安全带和能量制动必须受到严格的检测，无论车是不是在M城造的。显然地，给更多的检测，就应该更能降低事故率。
