2-9.  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 much smaller than estimated because______

(A) many users who illegally copy programs never find any use for them

(B) most of the illegally copied programs would not be purchased 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（B）

(E) the number of programs that are frequently copied illegally is low in comparison to the number of programs available for sale

我选了A的原因是不了解with no serious interest in的意思。

是：没有兴趣，还是没有利益？

为什么不用without?

谢谢bryony 版主。我想起来了，从 serious可以看出来是兴趣。
