22. Over the last 10 years, there has been a dramatic
increase in the number of people over the age of 65
living in this region. This is evident from the fact that
during this time the average age of people living in this
region has increased from approximately 52 to 57
years.
Which one of the following, if true, would most
strengthen the argument?
(A) The number of people in the region under the
age of 18 has increased over the last 10 years.
(B) The birth rate for the region decreased
significantly over the last 10 years.
(C) The total number of people living in the region
has decreased over the last 10 years.
(D) The number of people who moved into the
region over the last 10 years is greater than the
number of those who moved out.
(E) The average age for people in the region is
higher than that for people in surrounding
regions.

觉得这道题没有好答案呀. 也就A和D接近些,而且也不分上下. 多谢.

不明白，有人出来解释下吗？

我顶A，

AB都是加强，A更强

这个地方，在18岁人口增加的情况下，人均年龄仍能从52增加到57，恰恰说明了65岁人口的戏剧性增加。

看似削弱，实为加强
