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是答案，是not+削弱（削弱了结论）

为什么C不是呢？

原因：clark通过了政府的test

结论：买clark,不要买国外的便宜的零件。

我觉得C就是取非就是：all foreign-made parts satisfy government standards。就是说明原因不成立，有果无因。

请教NN，我推断哪里出了问题？谢谢！！！！！

all foreign-made parts satisfy government standards

满足不满足政府标准并不重要，重要的是你必须通过政府的测试，那么才知道它是好的。文中已经说对于外国产品你很难判断是不是好：

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.

意思就是没有证书保证它的质量，并不意味着它的质量就一定不好，只不过是你无法确认而已。
