The high cost of productions is severely limiting which operas are available to the public. These costs necessitate reliance on large corporate sponsors, who in return demand that only the most famous operas be produced. Determining which operas will be produced should rest only with ticket purchasers at the box office, not with large corporate sponsors. If we reduce production budgets so that operas can be supported exclusively by box-office receipts and donations from individuals, then the public will be able to see less famous operas.

Which one of the following, if true, would weaken the argument?

(A) A few ticket purchasers go to the opera for the sake of going to the opera, not to see specific operatic productions.

(B) The reduction of opera production budgets would not reduce the desire of large corporate sponsors to support operas.

(C) Without the support of large corporate sponsors, opera companies
                    could not afford to produce any but the most famous of operas.

(D) Large corporate sponsors will stop supporting opera productions if they are denied control over which operas will be produced.（C）
            

(E) The combination of individual donations and box-office receipts cannot

没明白答案的意思，是说没有这些大赞助商只能表演最有名的戏剧还是连这些最有名的戏剧都表演不了

any but,

opera companies
                could not afford to produce any but the most famous of operas

可以理解成opera companies
                could only afford to produce the most famous of operas

right,

the conclusion is:

if we reduce production budgets so that operas can be supported exclusively by box-office receipts and donations from individuals, then the public will be able to see less famous operas.

we have to find an answer to show that public will be able to see not less famous opera.

answer C shows that only famous operas will be produced.
