狒狒１３５－51

这到题死活看不懂，请牛人指点。

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.

答案是b

feifei上面的解释如下，也看不明白
B is correct. The passage reaches the conclusion that technical ingenuity usually brings benefits to those who have this ingenuity, whereas ethical inventiveness brings only pain to those who have this inventiveness. However the only reason is that 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. From the reason to the conclusion, there is a jump of concept. We need a link for the 2 concepts: people who have political power and the ingenuity. Choice B, by establishing the link, provides the strongest support. Choice B is actually an assumption for the argument.
