19. Speaker: Contemporary business firms need to recognize that avoiding social responsibility leads to the gradual erosion of power this is Davis and Blomstrom’s Iron Law of Responsibility: “In the long run, those who do not use power in a manner which society considers responsible will tend to lose it. “ The law’s application to human institutions certainly stands confirmed by history. Though the “long run” may require decades or even centuries in some instances, society ultimately acts to reduce power when society thinks it is not being used responsibly. Therefore, a business that wishes to retain its power as long as it can must act responsibly. Which one of the following statements, if true, most weakens the speaker’s argument? (A) Government institutions are as subject to the Iron Law of Responsibility as business institutions. (B) Public relations programs can cause society to consider an institution socially responsible even when it is not. (C) The power of some institutions erodes more slowly than the power of others, whether they are socially responsible or not. (D) Since no institution is eternal, every business will eventually fail.(E) Some businesses that have used power in socially responsible ways have lost it.

我选了e 答案是b 我认为b对，但不知道e错在哪里了

The speaker just said that those who do not act responsibly will tend to lose power.  But the failaure of those who act responsibly but lose power (E) can not justify that not to take responsiblity will not lose power.
