问题 According to the passage, one of the reasons why newborns in mountain communities are underweight is that their mothers are underweight.
The weight of a newborn has to do with the supply of oxygen even when he was still in his mother’s womb.

选项 A、Right
B、Wrong
C、Not mentioned

答案A

解析 第五段的第一句话是... babies born at high altitude are deprived of oxygen before birth.也就是说孩子还在母亲的子宫内时就已经缺氧了,这种缺氧的状况又影响荷尔蒙的释放和抑制,这些荷尔蒙又调节着婴儿的发育。
