### HideShow timer Statistics

Demographic experts predict that the global human population will reach its peak sometime in the middle of this century, after which it will begin to decline. Population growth is driven primarily by high birth rates in developing countries. It is known that when women have access to education and economic opportunities, they choose to have fewer children. Therefore, these experts propose expanding educational and economic opportunities to women in developing countries to bring about an earlier and smaller population peak.

Which of the following, if true, provides the strongest grounds to doubt that the experts' proposal, if adopted, will achieve its aim?
(A) The demographic experts proposing expanding opportunities for women in developing countries made the same recommendations over twenty years ago.
(B) The experts' prediction is based on realistic assessments of the educational and economic opportunities that can be made available to women in developing countries before that time.
(C) Many women in industrialized countries will continue to have four or more children despite access to a variety of educational and economic opportunities.
(D) The demographic experts fail to explain why an earlier and smaller population peak is preferable to a later and larger peak.
(E) Expanding opportunities to women in developing countries is generally considered a positive outcome regardless of its impact on population levels.

is it C?

C provides that many women who have access to educational and economic opportunities choose to have four or more children. Hence the experts proposal might not work.

Conclusion is :- Therefore, these experts propose expanding educational and economic opportunities to women in developing countries to bring about an earlier and smaller population peak.

Look at the conclusion indicator if you are not sure where the conclusion is .

So, Option C weakens this conclusion

I go for D......C seems wrong as industrialized countries is not equivalent to developing countries.....

IMO C.

Although "developing" countries aren't the same as "industrialized" countries, it would seem to logically follow that if women in industrialized countries who have access to educational programs continue to have children in significant numbers, then those programs would have little to no effect on women in developing countries...which may ultimately wind up being industrialized countries.

Correct answer : B

This is a weaken question. The experts' proposal involves expanding opportunities for women so that affected women will have fewer children, thus limiting the size of the population peak that the same experts have predicted. We're looking for a choice that suggests that the proposal will not limit the size of the peak or cause it to occur earlier. Consider each one:

(A) This is irrelevant. If the proposal 20 years ago was not followed (and we don't know whether it was or not) the fact that it was made doesn't tell us whether it would be effective or not today.
(B) This is correct. The proposal is based on the assumption that greater opportunities could be arranged for women in developing countries. If the maximum possible opportunities are already present, and have been built into the prediction, the proposal will not bring about any changes in the population peak.
(C) The argument is concerned primarily with developing countries, not industrialized countries.
(D) It doesn't matter whether the goal is desirable; the question is concerned with whether the goal will be attained.
(E) This is outside of the scope. It may be true, but it doesn't bear on whether the proposal will have the desired effect.

Where in the statement , it is written that opportunities exist ?

(C) Many women in industrialized countries will continue to have four or more children despite access to a variety of educational and economic opportunities.
Correct. attempts are made to reduce global human population peak. Industrialized countries are part of global world.
(D) The demographic experts fail to explain why an earlier and smaller population peak is preferable to a later and larger peak.
(E) Expanding opportunities to women in developing countries is generally considered a positive outcome regardless of its impact on population levels.

I will try to answer why B is the answer.
P1 : Demographic experts want to peak the population in the developing country.
P2 : The reason they give for the success is that in developing countries women have access to education and economic opportunities, they choose to have fewer children.
Conclusion : Education and economic opportunities bring about an earlier and smaller population peak
Comparing B with C

(C) Many women in industrialized countries will continue to have four or more children despite access to a variety of educational and economic opportunities.
----->
The scope shift. We are not arguing whether they will have more children or not. The focus is whether women have access to sufficient educational and economic opportunities. If they DO premise P2 will start working. That is the deciding factor for the experts to succeed in this endeavor.

(B) The experts' prediction is based on realistic assessments of the educational and economic opportunities that can be made available to women in developing countries before that time.
------->
B : Articulate but answer. The important assumption for this endeavor to succeed is that the opportunities for education MUST be available in the developing countries. In the absence of this scenario the argument of the experts falls apart. In fact B weakens the argument that they will DEFINITELY succeed. It can be possible that the country has very little growth opportunities which will not affect the population and bring early peak.

They want to peak the global population ( 1st line of the argument )
