为什么空格处填forgot?

Even though Sara had practiced her speech repeatedly,she_its conclusion at the talk show为什么空格处填forgot?
你的疑问是什么呢?
填forgot完全符合语法语义.
译：尽管莎拉已经反复练习了她的演讲,在脱口秀时她还是忘记了演讲的结语.------语意上符合.
从句Even though Sara had practiced her speech repeatedly,用过去完成时,表示“在脱口秀前已经”；而主句she_its conclusion at the talk show用一般过去时,表示“脱口秀当时”的情况.------语法上符合.

有选项吗
