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
正确答案是D想知道C怎么不对。

C看起来和文章的逻辑不相关吧。文章就是说了是因为国外的质量不好（A），所以得出了be smart and insist on brand-name parts by Clark for your car（B）.  要建立这两者之间的关系，这个C无关.. C似乎只是再次说明了A的内容。而没有建立起AB之间的关系。

感觉把C取非也可以削弱啊，外国的都满足标准了，那么就和本国的一样好了，就没必要坚持国产了啊？还是可以理解成那个就算满足标准了，也没国产的好?

c no foreign-made parts satisfy our government standards 取非 ：not any satisfy到some might satisfy取非不是外国的“都”满足标准，而是some 可能满足标准。所以结果和文中的论据一样，still unknown whether it is poorly constructed；不能说明结论“用本国的是明智选择”一定错
