问题 Why may GM foodstuffs be liked by people in the future? [br] If we want to feed the world’s population in 2050, our food production needs ______.

选项 A、to increase by 30 percent
B、an increase of 300 percent
C、to increase to 3 billion tons per year
D、an increase of three times

答案 D

解析 细节题。由题干2050定位在第三段首句可知:到2050年,我们的食品产量须增长两倍才能跟上世界人口预计增至100到110亿的步伐。a three-fold increase“增长两倍”,即“增加到三倍”,故D正确。本题关键在于正确理解a three-fold increase的含义,B即是针对此处设计的强干扰项,an increase of 300%“增加了三倍”,即“增加到四倍”。
