6. Advertisement: For sinus pain, three out of four hospitals give their patients Novex. So when you want the most effective painkiller for sinus pain, Novex is the one to choose.
Which of the following, if true, most seriously undermines the advertisement’s argument?

(A) Some competing brands of painkillers are intended to reduce other kinds of pain in addition to sinus pain.

(B) Many hospitals that do not usually use Novex will do so for those patients who cannot tolerate the drug the hospitals usually use.

(C) Many drug manufacturers increase sales of their products to hospitals by selling these products to the hospitals at the lowest price the manufacturers can afford.

(D) Unlike some competing brands of painkillers, Novex is available from pharmacies without a doctor’s prescription.（D）

(E) In clinical trials Novex has been found more effective than competing brands of painkillers that have been on the market longer than Novex.

思路如下: most hospital give their patients Novex <> most effective
A) 無關 B)and E) support that Novex are more effective than other bands..
only C and D left

C) manufacturers provide low price - so attract more hospitals to use Novex
D) no need prescription -- easiler to obtain for patients

C and D 在如此的思路下 變得都像undermine the argument...
但答案是D)...
請指點一下~如何排除C
感恩~~

我對這題也有疑問。

我傾向於C....
畢竟題目裡說是因為醫院常開novex給病人（有醫師處方籤），才推導出novex是好藥的。
D卻說病人可以不用醫師處方籤而在藥房裡買到novex....

請大家幫忙解答。

（今天的另一點想法）
C) 如果不對會不會是因為它只說 Many drug manufacturers...但沒有點出Novex?

這是OG 11, organge book #10. THE ANSWER IS ((C)).

REASONING: what point undermines the advertisement's claim? The argument for Novex's effectiveness as a painkiller is based upon the hospitals' usage. Consider what might be deriving the hospitals' choice of medications to administer. 3 out of 4 hospitals might be giving their patients Novex not b/c it is the most effective painkiller for sinus pain, but because it is INEXPENSIVE. If this is the case, the argument is seriously undermined.
