8. In Malsenia sales of classical records are soaring. The buyers responsible for this boom are quite new to classical music and were drawn to it either by classical scores from television commercials or by theme tunes introducing major sports events on television. Audiences at classical concerts, however, are continually shrinking in Malsenia. It can be concluded from this that the new Malsenian converts to classical music, having initially experienced this music as recorded music, are most comfortable with classical music as recorded music and really have no desire to hear live performances.
The argument assumes which one of the following?
(A) To sell well in Malsenia, a classical record must include at least one piece familiar from television.
(B) At least some of the new Malsenian buyers of classical records have available to them the opinion of attending classical concerts.
(C) The number of classical concerts performed in Malsenia has not decreased in response to smaller audiences.
(D) The classical records available in Malsenia are, for the most part, not recordings of actual public concerts.
(E) Classical concerts in Malsenia are not limited to music that is readily available on recordings.

这道题给的答案是C， 我选得是B。怎么就想不通呢? Am I missing something here?
Please advice. Thank you.

B的成立与否并不影响结论的成立，即如果NOT B，并不WEAKEN结论。因为结论说have no desire to hear live performances。
C如果不成立，即number of classical concerts decreased，则可能是造成shrinking的原因，而不一定是结论中的原因了，所以NOT C，WEAKEN了结论。

I was confused by the answer when I did this one. I did not like C at all. But B has no relevance here. In the argument, opinion is not mentioned and I could not figure out what impact it has on attending a concert. My common sense does not help me.

I think C is not correct as the decrease "is in response to the smaller audience". So smaller audience first, then decrease. If you argue that it is a viscious cycle that the decrease then leads to even smaller audience, I could not see it in the argument. There is not such link.

I would pick D. So people are actually buy records of concerts. So records and concerts are quite similar and it explains why...

Please argue with me if you disagree.

BraveMBA, the confusion I have is that I am not sure what is the conclusion that we are weakening here. My original understanding is: "the new Malsenian converts to classical music, having initially experienced this music as recorded music, are most comfortable with classical music as recorded music and really have no desire to hear live performances" is the conclusion. The way B weakens the conclusion is that the new Malsenians didn't really heard from other people about the concerts, it's not because they have no desire, but because they don't have the necessary information about the concerts.

D I think also cannot weaken the conclusion since the recordings of the public concerts are also recorded music and not live performance. You cannot really say people likes listening recorded public concerts is the same as they likes listens live performance. They are two different concepts.

Which choice did you choice when you first did this set, braveMBA?
