有题想不通，请大牛指教

I have the same doubt about the explanation of OG!
Could someone give us a hand?Thanks advance.


But I agree that E is correct answer.
The argument tell us that "it takes several pounds of grain to produce one pound of meat".If people in gortland who increase their consumption of meat will radically decrease their consumption of grain,the amout of meat will increase.If so , even though per capita consumption of meat has also risen toward the world
average,the increase in the production of meat may satisfy the need of gortland.
Consequently, the conclusion that gortland will soon have to import either grain or meat or both will be seriously undermined.
No doubt , the contradictory of E will weaken the argument.
So , E is an assumption!

Welcome to dispute my view.

八戒

以下是引用kathy72在2003-10-29 21:59:00的发言：
202. B 的意思是说该国的人口数量保持稳定. 将其取非, 假设该国人口增加, 那么该国的粮食更不够吃了, 更应该从国外进口粮食了. 因此, 不但没有削弱结论, 反而加强了结论. 因此B不是假设.

Perfect!

B is confusing!The contradictory of B is that the population may either increase or decrease.If the population is increasing , the contradictory of B will be a sound support. But if not,that of B will seriously undermine the argument.
So , B is a double-sword!

Appreciate comments.
