Having more than the usual numbers of fingers or toes on the hands or feet is termed polydactyly.
A.
B. Having had more than the usual number of fingers or toes
C. Having more than the usual number of fingers or toes
D. To have more than the usual number of fingers or toes
E. To have more than the usual numbers of fingers or toes
confused between C and D. In fact I have two questions:
1. the actual confusion is when to use gerund and when to use infinitive.
2. the explanation says that "parallelism" is an issue here. could someone please elaborate?
Thanks
