问题 Variables such as individual and corporate behavior______nearly impossible for economists to forecast economic trends with precision.

选项 A、make it
B、make
C、it makes
D、makes it

答案A

解析 本题考查主谓一致及it充当形式宾语的用法。根据句子结构,主语是variables,such as individual and corporate behavior为后置定语,修饰variables,所以谓语动词用动词原形形式,故首先排除[C]项和[D]项。空后的nearly impossible充当宾语补足语,to forecast economic…充当真正的宾语,谓语动词后面必须由形式宾语补充完整,故答案为[A]make it。
