[求助]不知道怎么攻击Argument B1，请指教！

B1.The following appeared in a memorandum from the head of a human resources department at a major automobile manufacturing company to the company's managers:

“Studies have found that employees of not-for-profit organizations and charities are often more highly motivated than employees of for-profit corporations to perform well at work when their performance is not being monitored or evaluated. Interviews with employees of not-for-profit organizations suggest that the reason for their greater motivation is the belief that their work helps to improve society. Because they believe in the importance of their work, they have personal reasons to perform well, even when no financial reward is present. Thus, if our corporation began donating a significant portion of its profits to humanitarian causes, our employees’ motivation and productivity would increase substantially and our overall profits would increase as well.”

想问问大家是怎么写的？
