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
我认为应该选C,因为题目中已经指明government automotive tests是the toughest such tests in the world,当然满足此测试的零件质量好。但是如果foreign-made parts也满足此测试的话,那么就不能说明他们质量不好。
答案D中说满足政府标准的零件比cheap foreign made parts质量好,但是文中cheap foreign made parts只是foreign made parts的一部分,不能算作假设前提吧。
