(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

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
