问题 People will live under the ground because______.
People will lose some senses under the ground because______.

选项 A、the world are polluted
B、it’s dark there
C、they can’t see the far-away things
D、they can’t grow their own food in the sun

答案D

解析 由原文第二段中的“Scientists say that people who live in cities today are losing their senses of smell, touch and taste. They can’t smell the dirty air, they can’t taste the chemicals in their food.These senses are not as strong as before, when people lived in the country and grew their own food”可以推断出,人们各种感觉下降是因为不能在正常的光照下种植农作物,所以D选项符合题意。
