feifei-80请教下NN

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没问题,但为什么C不对那?feifei给出的答案居然说这个选项无关,totally confused!
argument得思路是因为Government的检查很严格,所以请用通过了Government检验的Clark产品而不要用国外的产品
那如果国外的产品跟Clark一样通过了检验,那Clark公司的argument也不能成立了的说.
NN解惑????谢谢

我想C无疑是个Assumption,对其取非，foreign-made parts satisfy our government standards,明显是个削弱，但这个Assumption似乎是太大了较之于D,没有必要，从经济学的角度，选个成本低的D（D架桥架得很漂亮！）
于是得出结论：架桥优于not+weaken

这道题很多人都在问，我想了很久。
关于楼主的问题，为什么C不对，请看下面用红色highlight的文字：
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
我个人理解是，在外国制造的零件里，那些看起来便宜的并不好。这句话并没有说所有的外国零件都不好，只是看起来便宜的不好。而且所谓的poorly也不一定就是不符合政府标准的。
