标题: GWD25－3-请教一道逻辑

Mel: The official salary for judges has always been too low to attract the best

Candidates to the job. The legislature’s move to raise the salary has

done nothing to improve the situation, because it was coupled with

a ban on receiving money for lectures and teaching engagements.

Pat: No, the raise in salary really does improve the situation. Since very few

judges teach or give lectures, the ban will have little or no negative

effect.

Pat’s response to Mel is inadequate in that it

A. attempts to assess how a certain change will affect potential members

of a group by providing evidence about its effect on the current members.

B. mistakenly takes the cause of a certain change to be an effect of that change

C. attempts to argue that a certain change will have a positive effect merely

by pointing to the absence of negative effects

D. simply denies Mel’s claim without putting forward any evidence in support

of that denial

E. assumes that changes that benefit the most able members of a group

necessarily benefit all members of that group.

参考答案是A，本人觉得C也并无不妥。

以前有过很多讨论，但还是没有定论，请教到底是A还是C？谢谢

SUPPORT A

I think C is point to a good aspect but the inadequate ones.It is a right way to stand positive effect merely by pointing to the absence of negative effect .There is nothing to blame.

In A,the mothod Pat used has it's flaw.In choice A ,it has been pointed out very clear and at a right way.

哦，偶好像明白鸟。。。斑竹的意思是不是那个"inadequate"才是题目真正的用意？C并没有道出Pat讲的话有什么不足够的地方，只有A清楚道明了P用现在的性质来推断未来的潜在性质这个point，偶的理解对吗？

但是我还是不清楚究竟a 指出什么逻辑谬～也就是a是什么意思？

给为能解释一下吗？

试图通过对一个变化对现在情况的影响来说明对未来情况的影响

就象AA里的七宗罪，过去怎样了不能代表未来的发展趋势；题目里就是现在very few

judges teach or give lectures不能说明以后

支持A,这题是围绕加工资的有效性来说的，不是BAN的有效性～

M加工资没作用，因为BAN禁止讲座。

F加工资有作用，因为现在很少J去讲座，BAN将来没有消极作用。

C讲一个变化的积极作用通过说它没有消极作用。

这里的变化是指的要不要加工资，而不是要不要取消BAN。

以下是引用leoozop在2007-1-12 15:25:00的发言：

看到这里，我才终于相通，太感谢了。

我觉得这道题目最奇怪的是时态
Mel:The legislature’s move to raise the salary has done nothing to improve the situation, because it was coupled with a ban on receiving money for lectures and teaching engagements.
使用了完成时和一般过去时，感觉这个move是已经发生的事情，也就是已经涨工资并且已经有ban了。
然而，
Pat: Since very few judges teach or give lectures, the ban will have little or no negative effect.
使用了一般现在时和将来时，又让我感觉这个ban尚未发生（即move尚未发生）。
那么，
到底这个move是发生了还是没发生呢。。。。。？

如果move尚未发生，Pat的结论显然假设了未来也是few judge will teach or give lectures，然后才得出结论the ban will have little or no negative effect. 这时与A选项的描述一致。A.attempts to assess how a certain change will affect potential membersof a group by providing evidence about its effect on the current members.

如果move已经发生了，那么very few judges teach or give lectures,这件事儿是在已经有ban的情况下的，所以ban可能是导致few的原因，而不是few可以推导出的结果。与B选项描述一致：B.mistakenly takes the cause of a certain change to be an effect of that change（这里a certain change指的是very few judges teach or give lectures）

C选项我觉得不是答案。C.attempts to argue that a certain change will have a positive effect merely by pointing to the absence of negative effects
不要忘记涨工资本身就是一个positive effect. Mel之所以认为move不positive就是提出了可能有ban的negative effect，那么Pat反驳了Mel，认为ban的negative effect是absent的，这样不就证明了move本身是positive的么。这样论证并没问题啊。

悲剧啊GMAC到底想让咱选什么？A or B
明白人帮忙讲解一下吧
