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.



答案：A
为什么是A呢？

If A is true, then "the system for the confirmation or disconfirmation of scientific findings" will not work any more. Then the conclusion, which is the first sentence of the stimulus, is baseless.

system没有用，因为其他科学家会去test。
weaken: 科学结果很久都不被challenge， 所以需要那个system
