Journalist: In physics journals, the number of articles reporting the results of experiments involving particle accelerators was lower last year than it had been in previous years. Several of the particle accelerators at major research institutions were out of service the year before last for repairs, so it is likely that the low number of articles was due to the decline in availability of particle accelerators.

(D)	Particle accelerators can be used for more than one group of experiments in any given year.
(E)	Recent changes in the editorial policies of several physics journals have decreased the likelihood that articles concerning particle? accelerator research will be accepted for publication.

Argument Evaluation
Situation A journalist attributes the low number of articles about particle accelerators in physics
journals to the fact that several accelerators at major research institutions had been out of
service the previous year.
Reasoning What point undermines the journalist’s argument? Th e journalist assumes that the
researchers’ lack of access to the accelerators is responsible for the decline in the number
of articles. What else could explain fewer articles? What if the decline is due, not to the
availability of the accelerators for experiments, but to policies regarding publishing
articles related to such experiments? An alternate explanation is that changes in the
editorial policies of physics journals, rather than the eff ect of the out-of-service
accelerators, could well be responsible for the lower number of published articles about
particle-accelerator research.
A Th is statement rules out the possibility that submitted articles were not published, and
eliminating this alternate explanation tends to support the argument.
B A decline in waiting time would seem to promote more articles about accelerator research being
written and published, not fewer.
C While the decline in articles could be explained by a decline in the number of journals, this
statement eliminates that alternate explanation.
D If the accelerators can be used for multiple experiments, then it is reasonable to expect more
articles related to them, not fewer.
E Correct. Th is statement properly identifies a point that undermines the journalist’s reasoning.
Th e correct answer is E.

哥，想听听你的个人想法，那个D为啥不行。

我看了OG的解释，觉得E没错，可D觉得也对眼，所以在此发帖。

哥，可以不引用og麻烦你口头语言解释解释吗？谢谢~

在物理杂志里面，去年报道particle accelerators实验结果的文章比前几年都要少。前年，一些particle accelerators在修理不能工作，所以文章数量的减少时由于particle accelerator的数量。

前提1: 文章数量减少
前提2：accelerators数量减少
结论是: 文章数量少时因为accelerators的数量少。
可以发现的是这个推理少了一个前提1和前提2之间的联系，即是否有accelerators就一定能发表。

题目要削弱，一种是削弱前提和结论之间的联系，或者是直接削弱结论。

D.accelertoars可以为其他研究小组共用。
E.发表正常改变，导致与particle accelerators相关的文章发表困难。

D如果正确，必须满足“只要研究了，就能发表”
而E，直接反驳了结论，E成立，不管accelerators的数量多少，结论都不成立。

所以E更好

麻烦了，哈哈！

削弱原因题，原题原因错，找别外原因???

这题大家选D,还是E？
