请教feifei-80


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


这题想了老半天,也查了老贴课还是没弄明白,为什么c不对,


如果想c取非foreign-made parts satisfy our government standards ---->应该也变得reliable,因为Clark parts通过了国家标准就认为是reliable....所以c取非后不也削弱结论么


请大伙帮我看看,哪里出了些推理问题

取非就是“一些foreign企业通过了这个测试”而不是“没有企业通过”

所以依然有买外国货有碰到烂货的风险,所以着并不削弱结论
