The argument requires the assumption that
A.
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。
望nn指教!!
C过于绝对化,段落推理的作者只是对国外部件可靠性产生置疑。何况没参与测试不等于不能通过测试。D是推理依赖的假设,若通过测试的部件差于国外部件,则推理不能成立
