. 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

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来正明正确的结果。A指出Scientific experiments can go unchallenged for many years，指出Poor scientific work is harmful，是weaken。

A. 无关

B. 无关

C. 无关

D. 无关

75. Advertisers are often criticized for their unscrupulous manipulation of people’s tastes and wants. There is evidence, however, that some advertisers are motivated by moral as well as financial considerations. A particular publication decided to change its image from being a family newspaper to concentrating one sex and violence, thus appealing to a different readership. Some advertisers withdrew their advertisements from the publication, and this must have been because they morally disapproved of publishing salacious material.

Which one of the following, if true, would most strengthen the argument?

A.The advertisers switched their advertisements to other family newspapers.
B.Some advertisers switched from family newspapers to advertise in the changed publication.
C.The advertisers expected their product sales to increase if they stayed with the changed publication, but to decrease if they withdrew.
D.People who generally read family newspapers are not likely to buy newspapers that concentrate on sex and violence.
E.It was expected that the changed publication would appeal principally to those in a different income group.

答案：C
思路：
A.支持但不是最强
B.advertisers考虑了publication转变了不同的读者群，还是financial considerations。
C.直接举证说明原因：是为了moral，应为sales会increase if they stayed with the changed publication，但sales会decrease if they withdrew。
D.无关
E.无关
