Question

We have gathered nearly 100,000 quilts, ___ up to half have gone to the flood-hit areas.

         A. with which           B. in which        C. for which      D. of which

Answer 1

D

解析:

which指代先行词quilts，介词of表示“部分”，定语从句的正常语序应该是up to half of which (= 100,000 quilts) have gone to the flood-hit areas。
