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?

Because of a driver education campaign, most drivers and passengers in cars that did have safety belts used them in 1966. Most of the new cars bought in 1966 were bought in the months of January and February. In 1965, substantially more than one-seventh of the cars in Morodia were replaced with new cars. An excessive reliance on the new safety features led many owners of new cars to drive less cautiously in 1966 than before. 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.

题干翻译
在莫罗迪亚，大多数汽车没有这些（安全带和助力转向）特征。安全带有助于在碰撞中防止受伤，助力转向首先有助于避免碰撞。但是，即使在1966年莫罗迪亚七分之一的汽车被新车取代，汽车碰撞和与碰撞相关的受伤数量并没有下降。 逻辑链
New cars replaced → No decline in collisions & injuries 问题类型
解释题 推理过程
已知有新车替换且新车有安全特征（理论上应减少碰撞和受伤），但实际碰撞和受伤数量未下降，需要找到一个原因来解释这种矛盾。 选项分析
A选项：由于驾驶员教育活动，大多数有安全带的汽车中的驾驶员和乘客在1966年使用了安全带。这应该是减少受伤的因素，不能解释为何受伤数量没下降，排除。 B选项：1966年购买的大多数新车是在1月和2月购买的。购买时间与碰撞和受伤数量未下降没有直接关联，无法解释，排除。 C选项：1965年，大大超过七分之一的汽车被新车取代。1965年的情况与1966年碰撞和受伤数量未下降无关，排除。 D选项：对新安全特征的过度依赖导致许多新车车主在1966年开车比以前更不谨慎。这就解释了虽然有新车有安全特征，但因为驾驶行为改变，碰撞和受伤数量仍未下降，当选。 E选项：1966年销售的新车中的安全带和助力转向无论是否在莫罗迪亚制造都要经过制造商严格的质量控制检查。质量控制检查只能说明安全特征本身没问题，不能解释碰撞和受伤数量为何没下降，排除。
