The period when the great painted caves at Lascaux and Altamira were occupied by Upper Paleolithic people has been established by carbon-14 dating, but what is much more difficult to determine are the reason for their decoration, the use to which primitive people put the caves, and the meaning of the magnificently depicted animals.

(A) has been established by carbon-14 dating, but what is much more difficult to determine are

(B) has been established by carbon-14 dating, but what is much more difficult to determine is

(C) have been established by carbon-14 dating, but what is much more difficult to determine is

(D) have been established by carbon-14 dating, but what is much more difficult to determine are

(E) are established by carbon-14 dating, but that which is much more difficult to determine is

这道题看视频选的是a，但是看下面评论有说ron在曼哈顿讨论里答案是b

所以这题答案到底是什么？

用and连接起来的后面是用单数复数？

感谢！！！

肯定是B。前面主语决定单复数，what is more...就是单数

RON在视频里讲过，如果是A be B的结构中，be动词前面的可以做主语的话就是主语，否则主语就在be动词后面，形成了倒装结构。
这道题be动词前的what is much more difficult to determine是名词性从句中的主语从句，可以做这句话的主语，而主语从句的谓语动词一般都用单数，和后面的list无关。

虽然让我直接做题，根据题目的what is much more difficult to determine我会选B。
但是你这么一说，我突然想到一个知识点，
如果改写题目，The reason for their decoration, the use to which primitive people put the caves, and the meaning of the magnificently depicted animals is(are) difficult to determine.
这里就应该用are了

只有主谓一致，没有谓宾一致.
