9. Advertisement: Clark brand-name parts are made for cars manufactured in this country. They satisfy all of our government automotive test—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 parts are not suitable for cars manufactured in this country

(D) parts that satisfy our government standards are not as poorly constructed as cheap foreign-made parts（D）

(E) if parts are made for cars manufactured in our country, they are not poorly constructed

这个题目觉得E也是假设，取非之后是if parts are made for cars manufactured in our country, they are poorly constructed，Clark这个牌子是made for cars manufactured in this country. 这样不是说clark是poorly constructed，不是就削弱了结论了吗，费费135中给的解释说E是加强，那么怎么区分呢？

还有看到以前的版主说C中no 取非是not all,怎么觉得取非后是 all....啊，麻烦解释一下。谢谢！

''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.'' 这句话是说foreign-made parts得质量良莠不齐-- 有的好有的差，所以，有可能买到劣质品。但是，你也有可能买到好货。因此，要想说服人买clark brand-name parts 光说它达标不行，你也不知道达标产品是不是劣质品。但是，d 选项说只要达标，再差也不会像cheap foreign-made parts那样差。这就是在说明，clark brand-name parts 的总体质量要强于foreing-made parts.

C的缺陷在于，达标不代表你的货里没有poorly constructed products.

Satisfying the national standards = without poorly constructed products?
