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.

选项
A、arguable
B、noticeable
C、negligible
D、significant
答案
C
解析
句意关系题。根据空格后的提示,可知一些地区稻米和大豆的收成和其他地区的损失相互抵消。因此这种影响是很小的,选negligible“不重要的;很小的;不值得考虑的”。根据下文提示,可以首先排除noticeable“明显的”和significant“重大的”。既然下文已经明确指出收成和损失互相抵消,所以这种影响就是可以确定的。因此排除arguable“可争论的”。
