A firm that specializes in the analysis of handwriting claims from a one-page writing sample that it can assess more than three hundred personality traits, including enthusiasm, imagination, and ambition.
B.from a one-page writing sample it has the ability of assessing
C.the ability, from a one-page writing sample, of assessing
D.to be able, from a one-page writing sample, to assess
E.being able to assess, from a one-page writing sample,
I always take it for granted that noun is better than verb. I think "the ability of assessing" is better than "to be able to assess". However, the key is D. Who can explain the reason why C is not the right answer?
