PharmaCorp,which manufactures the drug Aidistan,claims that Aidistan is more effective than the drug Betatol intreating Puma
Syndrome.To support its claim PharmaCorp cites the fact that one of every two victims of Puma Syndrome is treated successfully
with Aidistan alone,as opposed to one out of every three treated with Betatol alone.However,PharmaCorp's claim cannot be taken
seriously,in light of the fact that the presence of Gregg's Syndrome has been known to render Puma Syndrome more resistant to
any treatment.
Which of the following,if ture,would most support the allegation that PharmaCorp's claim cannot be taken seriously?
A.Among people who suffer from both Puma Syndrome and Gregg's Syndrome,fewer are treated with Aidistan than with Betatol
B.Among people who suffer from both Puma Syndrome and Gregg's Syndrome,fewer are treated with Betatol than with Aidistan
C.Gregg's Syndrome reduces Aidistan's effectiveness in treating Puma Syndrome more than Betatol's effectiveness in treating the
same syndrome.
答案是A，解释说：此论断依赖于一个假设，即在Puma Syndrome的患者中服用Betatol治疗的人出现的情况比服用Aidistan的人出现Gregg's Syndrome
的情况要多。A基本上肯定了这个假设，尽管表述方式略有不同。假定Gregg's Syndrome 使得Puma Syndrome的治疗效果减弱，如果两种病症都有的患者服用Betatol进行治疗，而只有Puma Syndrome的患者服用Aidistan治疗，那么会显得疗效很好，尽管缺少Gregg's Syndrome实际上可能是解释
不同疗效的的关键因素。
这里说的假设是PharmaCorp‘s claim的还是整篇论断的？treated能不能做治愈讲？The fact that the presence of Gregg's Syndrome has been known to render Puma Syndrome more resistant to
any treatment.能把这句和答案一起翻译一下么，没看懂
还有错误选项C的解释是，本身没有提供有用的信息。由于没有分别提供服用Aidistan和Betatol后出现两种病症的人数，所以不能评价C对论断
的作用。
可是我感觉C说了GS对Aidistan的影响比Betatol大，所以weaken了PharmaCorp's claim
