Wheat yields in recent years were down by more than 10 percent in Russia and by a few percentage points (2)______ in India, France and China compared with(3)______ they probably would have been without rising(4)______, according to the study.

C、from
D、for
答案
A
解析
短语搭配题。此处需要在challenges“挑战”后面填一个介词,说明未来几十年粮食生产受到的挑战会加大,因此选A项,challenge to“对某人或某事的挑战”。challenge of和challenge from均表示“来自某人/某事物的挑战”,与句意刚好相反。challenge for是指为了获得某事物而进行的挑战,也与句意不符。
