OG11-43

11. 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

我能选B, 但我想问关于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.
and also for E:
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.

不好意思,老题重复问了,有点晕,看不动了

E項將某种软件的盜版量和待售量比,由于待售量是和厂家计划生产的多少有关,假如盗版500份,厂家生产了1000份,比例占50%。而厂家生产10000,只占5%。

最佳方法我觉得是 (illegal copy qty)/(Actual sales qty + illegal copy qty)

D項同理也是不对的,即使盗版软件损失占行业revenue的比例小, what if 整个正版软件的reveue占行业revenue的比例也很小呢?

假设:电脑产业总收入(100%)= 正版程序收入(5%)+其它收入(95%),如果盗版程序市场价值占电脑产业总收入5%(符合D的描述),则盗版程序的价值相当于正版程序的全部收入,电脑产业在程序这一块的损失那是相当巨大。

假设:电脑产业总收入(100%)= 正版程序收入(95%)+其它收入(5%),如果盗版程序市场价值占电脑产业总收入5%(符合D的描述),则盗版程序的价值仅相当于正版程序全部收入的5/95,电脑产业在程序这一块的损失不是那么明显.

这个题目是加强题目,d和e选项都是犯了比较对象的不同,所以不正确,见我的解释。我下一层想说的意思是我们不能作对了题目就完了,其实d和e只要稍微变一下都有可能成为很好的加强,比如程序的每年收入占电脑产业很大比重的话,的确不能加强电脑产业界的结论,这就是我的反之的意思,可能没有很好的表达。

  显然如果程序的每年收入只占电脑产业很小比重的话,的确不能削弱电脑产业界的结论。(反之,这个答案就是队的)

--不好意思,我没明白这句话?反之,这个答案就是队的?

其实D和E可以通过它们都没有说明白非法拷贝的人是否是潜在的顾客来排除,如果他们是潜在的顾客,即会去买正版的情况下,那么才会有actual loss; 如果他们不去买,就没有actual loss.

我觉得我这么想的话,D,E就直接排除了。

可是我看了解释This comparison is faulty,就想糊涂了,到底这个比较对象不同,意思有什么不同呢?

D:

the context of total industry revenues vs.  the context of total sales of programs.

E:

the number of copies sold  vs. the number available for sale

难道比对了,D或E就对了么?

谢谢ls的

我还是没转过弯来,等我再想想,大脑缺氧阿,ft

hehe,搂住还是挺仔细的,的确这个题目很容易作对,因为忽略了d,e选项成为正确选项的可能性,D)the total market value of all illegal copies is low in comparison to the total revenue of the computer industry。这个选象是把非法拷贝程序的市场价值和整个电脑产业的总收入相比较,显然如果程序的每年收入只占电脑产业很小比重的话,的确不能削弱电脑产业界的结论。(反之,这个答案就是队的)

(E)the number of programs that are frequently copied illegally is low in comparison to the number of programs available for sale,也是犯了同样的错误:显然如果这些可以出售的软件有绝大部分没有出售的话,那么也不能削弱电脑产业界的结论。注意这里比较的其实是非法拷贝价值占总拷贝价值的比例。

这个问题只要稍微换一下答案就不同,值得好好琢磨
