885补充128题

128. During the Renaissance, scholars were uncertain as to be location of Troy, and by the eighteenth century many historians doubted that Troy had ever existed.

(A) doubted that Troy had ever existed

(B) doubt that Troy has ever existed

(C) were in doubt as to the existence of Troy

(D) were doubtful concerning Troy’s existence（A）

(E) had doubts about Troy’s ever existing

以简洁来说,的确是A最佳,但弱弱的我,是因为想要跟前头的scholars were uncertain as to be location of Troy平行,所以选了C many historians were in doubt as to the existence of Troy,对不起,问题很蠢,请NN们教教我吧!谢谢!
