19. Smith: Meat in the diet is healthy, despite what some people say. After all, most doctors do eat meat, and who knows more about health than doctors do? Which one of the following is a flaw in Smith’s reasoning?

(A) Attacking the opponents’ motives instead of their argument

(B) Generalizing on the basis of a sample consisting of a typical cases

(C) Assuming at the outset what the argument claims to establish through reasoning

(D) Appealing to authority, even when different authorities give conflicting advice about an issue

(E) Taking for granted that experts do not act counter to what, according to their expertise, in their best interest

The key is E. 本句什么意思啊？B为什么不对呢？

1。B说的本来就不是逻辑错误，既然是typical的例子，当然可以generalize

2。原文没有从特殊到一般的generize过程。

3。E的意思为想当然的认为专家没有做不利于他们自己的事
