452.During the Renaissance, scholars were uncertain as to be location of Troy, and by the eighteenth century many historians [U]doubted that Troy had ever existed.[/U]
A.
B. doubt that Troy has ever existed
C. were in doubt as to the existence of Troy
D. were doubtful concerning Troy's existence
E. had doubts about Troy's ever existing
"existence" is the noun form of exist, why use "existing" to replace it? The real noun form is prefered to "v+ing" when the real noun form exists~ But 'Troy's existence' or the 'existence of Troy' doesn't have sense of time, which is not as good as A.
