15.   Sven: Trade unions are traditionally regarded by governments and economists as restraints of trade, working against the complete freedom of the economy, but I believe that unions are indispensable since they are often the worker’s only protection against exploitation.

Ravi: I don’t agree. The exploitation of the workers and their work is a normal part of ordinary trade just like the exploitation of natural or other material resources.

Sven and Ravi will not be able to resolve their disagreement logically unless they

(A) define a key term

(B) rely on the opinions of established authorities

(C) question an unproved premise

(D) present supporting data（A）

                (E) distinguish fact from opinion

答案是A， 整个题没看懂，请nn执教。谢谢

工会传统上被政府和经济学家看成是对贸易的一种限制，对贸易自由起到抑制的作用，但是，我觉得工会必不可少因为它通常是唯一能使工人不受剥削的保护。

我不同意，获取/使用工人和他们的工作是贸易的一个普通的组成部分，就象人类使用自然和原料资源一样。

The key term is "exploitation". This words has two slighly different meanings: (1) to use something for advantage, which applies to the word from RAVI，中文讲就是简单的使用获取; (2) To use something or someone UNFAIRLY for one's own advantage, which applies to Sevn,中文讲是剥削.

mygoalusa. Thank you for your excellent explaination. I really feel that this kind of problems are very diffcult. Since I will take the GMAT test and I do the lsat section just to practise my logic and reading comprehension, I sometimes do not pay enough attention to that kind of problems that are not contained in GMAT. But I do not know whether it is suitable.
