Wheat yields in recent years were down by more than 10 percent in Russia and by a few percentage points【C2】______in India, France and China compared with【C3】______they probably would have been without rising【C4】______, according to the study.
Corn yields were【C5】______a few percentage points in China, Brazil and France from what would have been【C6】______said the researchers, whose findings were published in Friday’s【C7】______of the journal Science.

选项
A、prices
