请高手讲解题思路？
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

Peace

To Lstzhang,

请问第3题答案是不是B？

第20题答案是不是A？

请告诉我答案对不对，好吗？ 谢谢！

我感觉这种逻辑考察的逻辑fallacy并不难，难主要难在阅读，
我总觉得多做一点题，然后彻底地读懂题，答案应该是跃然纸上的。

I agree,No.3 B;No.20 A

Sometime we  don't know what the exact answer should be, but when we read through the passage and the answer , we will find  one answer can best explain ,or support the passage.In some cases we see answer through a sense not just logical thinking.

Above all,reading comprehension is the most impotant thing we should care.

To Isuffering,

I like your quote very much and am encouraged by the high spirit conveyed in this quote.

Would you mind I expand your quote to:

I came, I suffered, I survived and I thrived !!!

呵呵！

Good Luck!!!
