问题 What’s the main topic of the passage?
If a poor country managed to provide enough food for children, the yearly economic growth rate would______.
选项 A、drop
B、not change
C、rise
D、exceed 2 percent
答案C
解析 细节题。根据题干的关键信息provide enough food for children和yearly economic growth rate与原文第三段最后一句的improved nutrition和economic growth对应。第三段最后一句说...poor countries could possibly double their economic growth if they improved nutrition...可知，如果穷国能够改善儿童的营养，年度经济增长率可能会翻倍，故C为答案。A、B和C的意思相反，所以可以排除。由这一段的第三句话中的...at a rate of two to three percent yearly...可知穷国目前的经济增长率是2～3%，那么可推断出双倍增长后可能的经济增长率范围为4～6%，排除D。
