7. 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 finding, namely, the replication of results by other scientists. Poor scientific work on the part of any one scientist, which can include anything from careless reporting practices to fraud, is not harmful. It will be exposed and rendered harmless when other scientists conduct the 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.
WHY A?
11. “If the forest continues to disappear at its present pace, the koala will approach extinction,” said the biologist.
“So all that is needed to save the koala is to stop deforestation,” said the politician.
Which one of the following statements is consistent with the biologist’s claim but not with the politician’s claim?
(A) Deforestation continues and the koala becomes extinct.
(B) Deforestation is stopped and the koala becomes extinct.
(C) Reforestation begins and the koala survives.
(D) Deforestation is slowed and the koala survives.
(E) Deforestation is slowed and the koala approaches extinction.
WHY B?
