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
老问题了，但还是不懂，牛牛帮忙解释下， B为什么对， D为什么不对阿。 请教了
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
Premise:Most of the illegal copying is done by people with no serious interest in the programs

B 题目中说了他们没兴趣所以也不会去买
D题目中没有任何前提证明盗版和全部收入的比例问题，所以不能得出
做逻辑题目的时候一定要根据题目本身所提供的信息推论,不能加入常识,题目中的观点是说"盗版不会引起收入损失,因为盗版人本身就没兴趣去买"(即便是没有盗版他们也不会成为购买的客户)
D) the total market value of all illegal copies is low in comparison to the total revenue of the computer industry
D意思是盗版所占的收入(引起的损失)比起公司的全部收入来说微不足道, true but invalidity,这个是也许对的,但是根据题目无法推论出来,也就是从文章中找不到推理的起点,所以不选
