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

D是对的，我承认。但看这句 “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.”此为author 认为要用C而不用国外货的原因，然而C选项取非的话，就否定了这个原因，因为一些外国货也通过了Gtest，所以如果因为C产品通过了Gtest而要顾客选它的话，这些外国货也应被选。于是结论不成立，于是这选项是

not+weaken的假设。

题目是问要求的假设，也即没有该假设，上述论述则不成立．Ｃ选项显然不符合要求，比如说即使外国产品通过了ＴＥＳＴ，达到了政府的标准，但有可能价格更高．

但原文没有说到价格也是一个考量因素啊。如果可以随便这么说的话，即使D不成立，C产品和外国产品一样差，也可以是C的价格更便宜，所以还是要选则C产品啊。

我知道这样好像有点吹毛求疵了，但原文的论调是，因为我们的产品通过了test，而外国的产品质量没保证，所以选择我们的吧！！

一旦外国的产品也通过了这个所谓的test，又凭什么还要一定选Clark的东西呢
