请教大全-17-4

4.     olitician: Fewer people are entering the labor market now than previously. If the economy grows, the demand for motivated and educated people will far outstrip the supply. Some companies have already started to respond to this labor-market situation by finding better ways to keep their current employees. Their concern is a sure indicator that the economy is growing.

Which of the following is the best criticism of the politician’s reasoning?

(A) The fact that companies are making prudent有先见之明的 preparations for a possible future development does not mean that this development is already taking place.

(B) The fact that some companies now try harder to keep their employees does not mean that they used to be indifferent to employee morale.

(C) The fact that demand will outstrip supply does not mean that there will be no supply at all.

(D) The fact that the number of new entrants into the labor market is declining does not mean that the number of new entrants is lower than it has ever been.（A）

(E) The fact that current employees have become more valuable to some companies does not mean that those employees will do their jobs better than they used to.

请问这T为什么选A啊？D为什么不对呢？

顶~~~~`

Fewer people are entering the labor market now than previously

我觉得这句话就可以解决掉D了，现在确实就是比以前少。

我试一下:

If the economy grows>remand increase并不等于remand increase >economy grows, 这是典型的因果倒置, if A, then B, 不能推出if B, then B.

你有时间的话,参考一下lawer_1的帖子吧, 那是一个大NN.
