During the past 1. 65 million years, there have been four major episodes of global cooling, which resulted in great migrations of animals and plants. Yet, the earth remained.

B、More children in Africa are suffering from hunger.
C、Fewer children worldwide are suffering from hunger.
D、More children worldwide are suffering from hunger.
答案 C
