(单选题)

Variables such as individual and corporate behaviour ______ nearly impossible for economists to forecast economic trend with precision.

A.make

B.make it

C.making

D.makes it

参考答案：B

参考解析：

考查主谓一致。句意：个人和集体行为的变化使得经济学家几乎不可能精确地预测经济发展趋势。with，together with，along with，as well as，like，such as后的谓语动词，应与该连词前的主语保持一致，故本题谓语动词与复数名词variables保持一致，同时加上it作其形式宾语。故选B。
