B.by the United States government's satisfaction, impose

C.with the United States government's being satisfied, imposing

D.to the United States government's satisfaction, impose      D）
E.to the United States government's satisfaction, imposing

请问这题为什么是begin 跟 impose 平衡啊。。。前面已经有一个谓语动词enable了，然后就又有一个begin。。。如果是两个句子，为什么没有连词，如果是1个句子，那begin为什么是原型啊。。。不死不得其解，求NN解答

三个动词不定式的平行，省略了后面两个的to: single out，begin，impose。

哦哦， - -原来这样都可以省略。。那是不是如果出现一个其他地方都一样的，只是begin 和 impose 前面都加了to，那么是选择省略的。还是不省略的呢？
