请教费费宝典41和两道老机经

41. Raymond Burr played the role of lawyer Perry Mason on television. Burr’s death in 1993 prompted a prominent lawyer to say “Although not a lawyer, Mr. Burr strove for such authenticity that we feel as if we lost one of our own.” This comment from a prestigious attorney provides appalling evidence that, in the face of television, even some legal professionals are losing their ability to distinguish fiction from reality.

The reasoning in the argument is flawed because the argument

(A) takes the views of one lawyer to represent the views of all lawyers

(B) criticizes the lawyer rather than the lawyer’s statement

(C) presumes that the lawyer is qualified to evaluate the performance of an actor

(D) focuses on a famous actor’s portrayal of a lawyer rather than on the usual way in which lawyers are portrayed on television

(E) ignores the part of the lawyer’s remark that indicates an awareness of the difference between reality and fiction

该题的答案选E，网上的XDJM可否告知该题的解题思路。

48. 其二：以前用于治疗某种传染病的药是A和B。 这两种药的疗程是7天，但由于很多人服药3天后就停药了，这些人中很多再次被传染。现在发明了一种新的药C，这种的疗程只有3天。所以,让患者服用新药再次被传染的机会比服用旧药低。
问：哪项支持结论?
A, 新药虽然疗程短,但价格和旧药相同.
B, 那些对A过敏的患者,对C也过敏.
D, 已经有一些医生开处方时,给患者开新药.
E, 不管新药,旧药,大多数患者在服用3天后病都会好.
还有一个选项忘了.总之,我觉得哪个都不象正确答案.

某药A用来治疗传染病7天一疗程，但好多人3天就不吃了，所以再度被传染的概率比较大，有一种新药一疗程3天，用该药可以更有效的抑制再度被传染的现象。
以前机井中漏掉了一个答案C:新药可以更有效ERADICATE INFECTION。
为什么该题选E？
