Ok I agree this argument is silly. Especially because the author didn't specify if the photocopying by teachers are considered as "illegal photocopying". (Perhaps he didn't want to imply that the teachers are engaged in anything illegal, but that is out of the point.) Now let's assume that this is what he meant (at the risk of being criticised by baner for adding assumptions
) because otherwise his argument would fall all apart.
Publisheres believe they suffer great loss due to illegal copying
Most copying are done by teachers who give each student an illegal copy
The teachers have to do so because the schools are poor
Which of the following is most propably the point towards which the author of the above passage is moving?
(In my opinion he could move toward any point, the way he goes.)
(A) Magazine publishers should provide free copies of their magazines to schools.
Sounds a little outrageous. But he may very well arrive this point: Give it to them for free if you don't want them to do it illegally. However this does not say anything about whether the publishers have lost revenue, and would make the first sentence irrelevent. Assuming that this guy is not totally out of loop, let's see if there's anything better than this that he has to offer.
(B) Preventing illegal photocopying would have no effect on magazine sales.
If illegal photocopying are prevented, then the poor teachers would not do the copying. But they are poor so they won't buy the magazines anyway, and thus no effect would be induced on the sales. The only problem with this one is the author only claimed that "most", not "all", photocopying are done by the poor teachers. So it is not very likely that he would claim "no" effect would be induced.
(C) Teachers should be prevented from photocopying magazine articles for their students.
The third sentence obviously shows that he was sympathetic toward the teachers so it is not very likely he wants to be so harsh toward the teachers?
(D) Eliminating illegal photocopying would prevent the magazine's publishers' loss of revenue.
See the first part of (B).
(E) Illegal photocopying does not depress magazine sales as significantly as publishers believe.
This is the most likely thing that he'll say. Not too extreme to both ends.
Ok seriously, the first sentence has determined that his conclusion should be something related to the publisher's revenue loss, so A and C are ruled out. B and D are too extreme to both end considering the fact provided and the way he described it ("most"). So E should be it, I say.
