21. Which one of the following assertions, if true, provides the most effective challenge to the author's conclusion?

(A) The general health of this country's population has improved over the past 40 years primarily because of new advances in medicine and nutrition, not because of pollution.

(B) There are several countries in the would in which there have been no restrictions on which there have been no restrictions on pollution over the past 40 years, and pollution levels have actually increased.

(C) Similar statistics show that, in several countries, the general health of the population has improved over the past 40 years, while pollution levels have actually decreased.

(D) Pollution levels would have increased even more than they have and the general health of the population would not have improved as much as it has without the restrictions that have been on the books.

(E) In the period prior to the past 40 years, pollution restrictions were nonexistent in this country and the general health of the population improved at a far slower rate than it did during the past 40 years.

答案是D，此题是削弱题吗？我觉得A也可以啊，谢谢！：）

why?

SORRY,I FOGOT TO PASTE THE PASSAGE.

This country does not need any more restrictions on pollution. In fact, we should abolish those that are currently on the books. In spite of various restrictions, pollution levels have actually increased over the past 40 years. Most importantly, dramatic statistics show that, as pollution levels have increased over this period, the general health of the population has improved rather than deteriorated.

This country does not need any more restrictions on pollution, 应该直接削弱restriciton, a, 没有指出restriction, pollution, health 德关系， d 虚拟语气

Good job! Choice A is really tricky and i was trapped by it. But it only weakens from general health point of view, not from pollution. So D is the BEST one.
