These days, everyone talks about being too busy. But all this busyness does not seem to result in things getting done. Just as many tasks are still left uncompleted, phone calls unreturned, and appointments missed as there were in the days before this outbreak of busyness. Therefore, people must not be as busy as they claim.
Which one of the following, if true, would most seriously weaken the conclusion in the passage?
(A) These days, looking busy is a status symbol.
(B) People have to do much more these days than before the so-called outbreak of busyness.
(C) People waste so much time talking about being busy that they fail to get things done.
(D) Just as many things are getting done now as before the so-called outbreak of busyness.（B）
(E) People have more leisure time these days than before the so-called outbreak of busyness.
我想问D为什么不对？
谢谢！
