The personal income tax did not become permanent in the United States until the First World War; before that time the federal government was dependent on tariffs to be their main source of revenue.

Athe federal government was dependent on tariffs to be their main source of revenue
Bthe federal government had depended on tariffs as its main source of revenue
Ctariffs were what the federal government was dependent on to be its main source of revenue
Dthe main source of revenue for the federal government was dependent on tariffs
Efor their main source of revenue, tariffs were depended on by the federal government

In C and E, on (preposition) is not followed by a noun.
Eliminate C and E.

虽然能选出正确选项，但关于这个解释在选项C的应用不太理解，Tariffes are what the federal government was dependent on.这句话有问题吗...问题不应该在于后面那to be吗求解答

我始终觉得，既然用了before that time ..这样的标志，后面就应该用过去完成时

C tariffs were what the federal government was dependent on to be its main source of revenue
表达太wordy ,awkward ..

to be这里的确不是很明白，觉得太不搭了... 即便改成as我还是觉得太不顺了太太wordy ,awkward
顺求高手解答

个人认为时态不是一个很好的判断点因为已经出现了before，不用过去完成时也可以表示时间先后

介词的这个点真的不是很熟练…很多时候不太敢用这个点来判断我貌似感觉这个C还有倒装？不确定哈

我的判断顺序是词性顺序动词>形容词副词>名词>动名词表达歧义越少越简洁就越优选这也是一个帮助做排除的点吧

C tariffs were what the f ...

这个用meaning理解加上before that time的提示可以判定过去完成时是最优选择但OG上包括ron还有一些论坛上的资料关于C的解释不太懂如1楼 “Tariffes are what the federal government was dependent on.”可能我语法比较弱看不出来这有什么问题啊
