以下是引用shirley8707在2008-4-18 21:30:00的发言:LAWYER哥哥,一道OG11的逻辑题目对于OG的解释不明白,请指教(这到题目OG10没有,没看到讨论过) 43. Which of the following best completes the passage below? The computer industry's estimate that it loses millions of dollars when users illegally copy programs without paying for them is greatly exaggerated. Most of the illegal copying is done by people with no serious interest in the programs. Thus, the loss to the industry is quite small, because_________ (A) many users who illegally copy programs never find any use for them (B) most people who illegally copy programs would not purchase them even if purchasing them were the only way to obtain them (C) even if the computer industry received all the revenue it claims to be losing, it would still be experiencing financial difficulties (D) the total market value of all illegal copies is low in comparison to the total revenue of the computer industry (E) the number of programs that are frequently copied illegally is low in comparison to the number of programs available for sale 对D的解释This comparison is faulty: the loss is not being considered in the context of total industry revenues but in the context of total sales of programs. 对E的解释This comparison is faulty: the low number of illegal copies would have to be compared with the number of copies sold, not the number available for sale. 我的疑惑是:为什么E是拿 不合法的COPIES的数量比上卖掉的数量低就能说明LOSS的少呢?我觉得应该是the low number of the number of copies sold compared with number of illegal copies 还有最近做OG,虽然作对了,把其他答案按照无关有关排除,觉得不应该在推理链上,比如是问削弱,选项中有支持的选项,但我当时是按照无关排除的,后来按照OG的思路去分析,也是合理的,这也可以支持。这就使我每次想选项是会多想一下,有时候会跳出逻辑链了,请问这个度该怎么把握呀? 谢谢您的答复 问题关键是东西只有本来能卖出去,也才有损失的问题.如果东西不好,非法COPY不会构成损失.因为不COPY也没人买.没有可能的收入,就没有损失存在. OG对E解释的意思是:因为原文讲的是损失的问题,所以比较的应该是能够造成收入或损失的.如果和available for sale比,那么如果这行业PROGRAMS本来都卖不出去,那么不管合法非法COPY,都不会构成损失.因为即使没人COPY,也卖不出去.如果和the number of copies sold比,非法COPY的很少,则说明损失比例还是很小. 对于削弱或支持题,用有关无关[排除后,还要注意相反项,如问题问削弱,答案出现支持项,反之也一样.办法是将相反项留到最后去排除. |
