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


    
答案是D。思路我能理解。可我的问题在红字部分。既然这种零件满足这个国家的测试要求,而这种测试又是世界上最严格的测试!!这么这个假设是不是有点多余???

标题: feifei-80 我明白了。是这样么?
我明白了,因为这是广告上的自吹自擂,可能有失客观,所以这个假设是必须的!对吧?那位童学能指点一下?

有些前提题目,是一眼或者两眼看出前提的,有些则要靠取非

本题就是,最可笑的是我看完5个选项觉得没有一个靠谱

但是针对D,取非,则发现,如果C这个通过了最严格测试的跟外面的cheap东西一样poorly constructed的话

最后一句的therefor....就不成立了。

LZ看看是不是。

嗯。因为我看到前提一说是通过了世界上最严格的测试,所以就根本没想到会和前提二的说外国零件可能粗制滥造挂等号。。。

取非选择有道理
