题目是这样的
The period when the great painted caves at Lascaux and Altamira were occupied by Upper Paleolithic peoples has been established by carbon dating, but what is much more difficult to determine are the use to which primitive peoples put the caves, the reason for their decoration, and the meaning of the magnificently depicted animals.
A.   has been established by carbon dating, but what is much more difficult to determine are
B.   have been established by carbon dating, but what is much more difficult to determine are
C.   have been established by carbon dating, but that which is much more difficult to determine is
D.   has been established by carbon dating, but what is much more difficult to determine is
E.   are established by carbon dating, but that which is much more difficult to determine is

然后我今天看的时候就纠结了，，，为什么determine后面是用is而不是用are呢？我能不能把后面的the use..., the reason...and the meaning 看成一个复合词呢？因为这三个都是determine的内容啊。。。

请各位走过路过的大侠帮忙答疑解惑，，我就先谢过大家了！~~^____^

对于what从句的单复数问题，如果what本身做主语,主句谓语由从句谓语决定 what在从句中做宾语主句谓语由主句表语/宾语决定。
本题what就是作主语，并且前面很清楚的给出what is much more。。。所以主句用is而不是are

她好像问的是what is much more difficult to determine are。。。为什么后面要用ARE呢？

LZ, “what is much more difficult to determine ”这里做主语，谓语只能用 “ is ”。

就是说其实determine后面的那个verb是由what这个从句决定的对吗？
因为之前看解释上说是因为后面的the use...是单数，，一下给纠结了。
