her mother came to help her for the first few months to begin her project.

A. Only; she was allowed

B. Only after; she was allowed

C. Only after; was she allowed

D. Only; was she allowed

答案：

A. Only; she was allowed

B. Only after; she was allowed

(答案→)C. Only after; was she allowed

D. Only; was she allowed

解析：考查only的倒装。句意：直到她母亲，头几个月来帮忙，她才开始了她的项目。only后面加after引导的状语从句，主句用倒装。所以答案选C。
