If a poor country managed to provide enough food for children, the yearly economic growth rate would ______.
A.drop
B.not change
C.rise
D.exceed 2 per cent

参考答案

正确答案:C
解析:根据题干的关键信息economic growth rate定位到文章的第三段的第一句话links malnutrition to economic growth in poor countries。随后的第二句话...lack of nutrition in early childhood can cost developing nations up to three percent of their yearly earnings...(儿童缺乏营养会导致发展中国家损失最高可达百分之三的年收入),由此可判断儿童营养不良会拖累经济增长率,接下来,由这一段的第四句话... 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增长,由此可判断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)。
