4. Campaigning for election to provincial or state office frequently requires that a candidate spend much time and energy catering to the interests of national party officials who can help the candidate to win office. The elected officials who campaign for reelection while they are in office thus often fail to serve the interests of their local constituencies.

Which one of the following is an assumption made-by the argument?

(A) Catering to the interests of national party officials sometimes conflicts with serving the interests of a provincial or state official's local constituencies.

(B) Only by catering to the interests of national party officials can those who hold provincial or state office win reelection.

(C) The interests of local constituencies are well served only by elected officials who do not cater to the interests of national party officials.

(D) Officials elected to provincial or state office are obligated to serve only the interests of constituents who belong to the same party as do the officials.

(E) All elected officials are likely to seek reelection to those offices that are not limited to one term.

Ans: A, I choose C

I think A, C both ok, what is the difference between them?
我经常觉得几个选项皆可，这怎么办？

24. Explanation must be distinguished from justification Every human action potentially has an explanation that is with sufficient knowledge it would be possible to give an accurate description of the causes of that action. An action is justified only when the person performing the action has sufficient reasons for the action. According to many psychologists, even when there is a justification for an action, that justification often forms no part of the explanation. The general principle, however, is that only an action whose justification, that is, the reasons for the action, forms an essential part of its explanation is rational.

If the statements in the passage are correct, which one of the following can be properly concluded form them?
(A) When a human action is justified, that action has no explanation.

(B) If there are any reasons among the causes of an action, then that action rational

(C) Some psychologists believe that the justification for an action never forms an essential part of its explanation

(D) There are actions whose causes cannot be discovered

(E) If any human actions are rational then reasons must sometimes be causes of actions

Ans : E
