Would you mind telling me what problem she had the plan?
A. to carry out
B. carrying out
C. carried out
D. with carrying out
网友回答
A. to carry out
(答案→)B. carrying out
C. carried out
D. with carrying out
解析：考查非谓语动词。She had carrying out the plan是修饰problem的定语从句，problem在从句中做had的宾语，即have problem/difficulty (in) doing sth
句意为你介意告诉我她开展这个计划存在的困难吗？
