PREP1-122,没开过贴的题。。。

Surveys have shown that in up to 40 percent of elderly people living independently in affluent

countries, the consumption of one or more essential nutrients is insufficient or they have deficient

levels of these nutrients in their blood.

(A) in up to 40 percent of elderly people living independently in affluent countries, the consumption

of one or more essential nutrients is insufficient or they have

(B) in up to 40 percent of elderly people who live independently in affluent countries, they consume

one or more essential nutrients insufficiently or have

(C) in up to 40 percent of elderly people who live independently in affluent countries, one or more

essential nutrients are consumed insufficiently or having

(D) up to 40 percent of elderly people living independently in affluent countries who consume

insufficient amounts of one or more essential nutrients or who have

(E) up to 40 percent of elderly people who live independently in affluent countries consume

insufficient amounts of one or more essential nutrients or have

这题我答案是做对了，选E

但有个疑问，ABC中的 in up to 40 percent of elderly people 有没有这种表达呢，prep的解释里没有涉及到。

我觉得应该是有的，只不过在这里不合适，意思没法理解
