Know the conclusion of the argument: No nation can long survive unless its people are united by a common tongue. Logic chain: If nation survives, then its people speak the same language.

E simply points out the above is not true in one country. Thus, E weakens the argument. -- by 会员 sdcar2010 (2011/3/31 21:18:31)
