请用这两个题目指点思路。
3. When workers do not find their assignments challenging, they become bored and so achieve less than their abilities would allow. On the other hand, when workers find their assignments too difficult, they give up and so again achieve less than what they are capable of achieving. It is, therefore, clear that no worker full potential will ever be realized.

Which one of the following is an error of reasoning contained in the argument?

(A) mistakenly equating what is actual and what is merely possible

(B) assuming without warrant that a situation allows only two possibilities

(C) relying on subjective rather than objective evidence

(D) confusing the coincidence of two events with a causal relation between the two

(E) depending on the ambiguous use of a key term


20. Graphologists claim that it is possible to detect permanent character traits by examining people's handwriting. For example, a strong cross on the "t" is supposed to denote enthusiasm. Obviously, however, with practice and perseverance people can alter their handwriting to include this feature. So it seems that graphologists must hold that permanent character traits can be changed.

The argument against graphology proceeds by

(A) citing apparently incontestable evidence that leads to absurd consequences when conjoined with the view in question

(B) demonstrating that an apparently controversial and interesting claim is really just a platitude

(C) arguing that a particular technique of analysis can never be effective when the people analyzed know that it is being used

(D) showing that proponents of the view have no theoretical justification for the view

(E) attacking a technique by arguing that what the technique is supposed to detect can be detected quite readily without it

第一题：B 忽略了正好的情况
第二题：A  
B、D、E都不太相关，C 说的似乎不符文章的结构

纯逻辑题往往有比较明显的逻辑漏洞，考的其实就是对选项的理解。把选项收集起来，搞清含义，举一些浅显的例子，这类题不会有大问题。
