73. There is no reason why the work of scientists has to be officially confirmed before being published. There is a system in place for the confirmation or disconfirmation of scientific findings, namely, the replication of results by other scientists. Poor scientific work on the part of any one scientists, which can include anything from careless reporting practices to fraud, is not harmful. It will be exposed and rendered harmless when other scientists conduct experiments and obtain disconfirmatory results.

Which one of the following, if true, would weaken the argument?

(A) Scientific experiments can go unchallenged for many years before they are replicated.

(B) Most scientists work in universities, where their work is submitted to peer review before publication.

(C) Most scientists are under pressure to make their work accessible to the scrutiny of replication.

(D) In scientific experiments, careless reporting is more common than fraud.

(E) Most scientists work as part of a team rather than alone.

思路：作者说no必要有一个新的出版confirmation系统，因为Poor scientific work is not harmful，other scientists conduct experiments来证明正确的结果。A指出Scientific experiments can go unchallenged for many years，指出Poor scientific work is harmful，是weaken。

我选了D，答案是A。这题的意思不是很理解，看了解释也还是不大懂，请赐教！！！
