Frederick Douglas’s struggle to abolish slavery and fight for civil rights of the Black Americans is the type of miserable experience ________ a touching movie might be produced.

(A) about which

(B) for whom

(C) from it

(D) with that

答案是(A) about which

我的问题是：

1.介系词about 可以换成其它的介系词吗?

2. the type of miserable experience about which a touching movie might be produced. 这到底是什么意思哩….

好像是说FD的废奴和争取黑奴权力的抗争，是touching电影的好题材。

这样翻译的化，用about倒是听合适。
