B.Citing faulty voting equipment, confusing ballots, voter error, and problems at polling places, a new study of the 2000 United States presidential election has estimated that 4 million to 6 million of the 100 million votes cast were not counted.
4 million to 6 million of the 100 million votes cast were not counted.
(A)which不能指代前面整句话,也离可能被修饰的词a new study太远,另外they没有指代对象;(C)Citing的逻辑主语是后面主句的主语votes,错;(D)cast在前,count在后,两者时态不对;(E)estimate用的是现在完成时,count用的是过去完成时,时态也不对,另外citing…在这里可能引起歧义,变成修饰election或者做状语修饰谓语,以及estimate引导宾语从句后面that不能省。其实(B)也不是最好,因为它把题目中的主干变成了从属,从属变成了主干,但这最多只是effective的错。
