费费逻辑愈作愈惨.......
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.
ans 是A
我怎么觉得叙述好像都在绕一些让我晕眩的资料呢?
Some cleaning fluids, synthetic carpets, wall paneling, and other products release toxins, such as formaldehyde and benzene, into the household air supply. This is not a problem in well-ventilated houses, but it is a problem in houses that are so well insulated that they trap toxins as well as heat. Recent tests, however, demonstrate that houseplants remove some household toxins from the air and thereby eliminate their danger. In one test, 20 large plants eliminated formaldehyde from a small, well-insulated house.
84. The passage is structured to lead to which one of the following conclusions?
(A) Houseplants can remove benzene from the air.
(B) Nonsynthetic products do not release toxins into houses.
(C) Keeping houseplants is an effective means of trapping heat in a poorly insulated house.
(D) Keeping houseplants can compensate for some of the negative effects of poor ventilation.
(E) The air in a well-insulated house with houseplants will contain fewer toxins than the air in a well-ventilated house without houseplants.
