80. Advertisement: Clark brand-name parts are made for cars manufactured in this country. They satisfy all of our government automotive tests-the toughest such tests in the world. With foreign-made parts, you never know which might be reliable and which are cheap look-alikes that are poorly constructed and liable to cost you hundreds of dollars in repairs. Therefore, be smart and insist on brand-name parts by Clark for your car.
The argument requires the assumption that
(A) Clark parts are available only in this country

(B) foreign-made arts are not suitable for cars manufactured in this country
(C) no foreign-made parts satisfy our government standards
(D) parts that satisfy or government standards are not as poorly constructed as cheap foreign made parts
(E) if parts are made for cars manufactured in our country, they are not poorly constructed

答案是D

问题：把E选项取非也能够否定原结论呀。为何不是E呢？
请NN们指教！

我也选E,请求指点！

我也是先排除了ABC。D和E想了一会。
我的感觉是，1。文章的中心是讨论Clark的产品，不能轻易的把范围扩大。
2。文章的逻辑链是 Clark 符合标准，而因为外国产品可能会poorly constructed，所以不能用外国产品，而用Clark的产品。这里有要有一个断桥，就是要说明符合标准的东西不会poorly constructed 。
不知道我说的对不对，等大牛。

parts are made for cars manufactured in our country不一定satisfy all of our government automotive tests，只有Clark brand-name parts是这样做的。

谢谢楼上的，理解了。definition的范畴问题

Clark brand-name parts 满足政府测试与结论之间没有直接因果关系，题目中逻辑关系是：因为foreign-made parts是poorly constructed，因此要选择Clark brand-name parts 。换言之，即是否poorly constructed是做选择的关键。达到该结论（选择Clark brand-name parts ）的必要条件是Clark brand-name parts 不是poorly constructed，也就是该结论的assumption.
这是我的想法，请大牛们指教。。
