In December of 1987 an automobile manufacturer pleaded no contest to criminal charges of odometer tampering and agreed to pay more than $16 million in civil damages for ( cars that were test-driven with their odometers disconnected ).
A. Cars that were test-driven with their odometers disconnected
B. Cars that it had test-driven with disconnected odometers
C. Its cars having been test-driven with disconnected odometers
D. Having test-driven cars with their odometers disconnected
E. Having cars that were test-driven with disconnected odometers
一遍下来读的不太懂,大致是汽车公司对O T的违法赔偿不作辩护并且同意支付多少钱关于被测试过O D 的车。
B C的代词不对,排除。看到D E直接就排除了,不懂想要表达什么,选了A。答案是D。麻烦老师讲解。

提问:
7/15寂静:所有员工都大于20岁. Of the 2000 employees, is the avg age at least 35?
1. 50% 员工是大于40岁
2. 25% 员工是大于65岁
这道题网上有C和E两种争论;我所不明白的点是:条件2中的25%是否包含在条件1的里面;我觉得答案应该是C。因为:35*2000=70000岁;(1)+(2)可得41*500+66*500+21*1000=74500>70000.不知道我的思路是否正确。谢谢老师的答疑!
