请教狒狒逻辑题

51. People who have political power tend to see new technologies as a means of extending or protecting their power, whereas they generally see new ethical arguments and ideas as a threat to it. Therefore, technical ingenuity usually brings benefits to those who have this ingenuity, whereas ethical inventiveness brings only pain to those who have this inventiveness.

Which one of the following statements, if true, most strengthens the argument?

(A) Those who offer new ways of justifying current political power often reap the benefits of their own innovations.

(B) Politically powerful people tend to reward those who they believe are useful to them and to punish those who they believe are a threat.

(C) Ethical inventiveness and technical ingenuity are never possessed by the same individuals

(D) New technologies are often used by people who strive to defeat those who currently have political power.

(E) Many people who possess ethical inventiveness conceal their novel ethical arguments for fear of retribution by the politically powerful.

B是如何起到增强作用的，是在想不出来，求教高手

首先看推理链：政治家喜欢new technologies 而不喜欢ethical arguments.所以搞technology的受益，搞ethic的倒霉。
这时就能发现两者之间有gap。为啥搞technical的受益，搞ethical的倒霉叻。就是政治家因为喜欢搞technology的而给他们rewards，因为不喜欢搞ethic而给他们处罚。这样，B就是best answer咯。其它都是无关项。

谢谢你
