大全B-13

彼岸无岸

13.   No nation can long survive unless its people are united by a common tongue. For proof, we need only consider Canada, which is being torn asunder by conflicts between French-speaking Quebec
and the other provinces, which are dominated by English speakers.



Which of the following, if true, most effectively challenges the author’s conclusion?




(A) Conflicts over language have led to violent clashes between the Basque-speaking minority in Spain
and the Spanish-speaking majority.



(B) Proposals to declare English the official language of the United States
have met with resistance from members of Hispanic and other minority groups.



(C) Economic and political differences, along with linguistic ones, have contributed to the provincial conflicts in Canada
.



(D) The public of India
, in existence sine 1948, has a population that speaks hundreds of different, though related, languages.（E）


(E) Switzerland
has survived for nearly a thousand years as a home for speakers of three different languages.

答案是E，但我选了C为什么不对？如果canada的conflicts是由于除了没有common language以外的其他原因才生的，那么不就削弱了吗？
期待大家指教，谢谢

糊香肠

C个人认为是个无关选项。。。文章有两个点，一个是long survive，另一个是多种语言，所以C无关
E很明显啊。。。。
