划线外分别是讲了三个risks，所以谓语动词用are哦，个人认为如果只是一个risk，那么谓语动词用is

what从句中concern为复数形式，后面的are和concern对应

此外，请看og10的一题：

og211.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

(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

正确答案为C：

（1）两个is保持一致

（2）第二个is和the reason保持一致
