83. Journalist: In physics journals, the number of articlesreporting the results of experiments involving particle accelerators was lowerlast year than it had been in previous years. Several of the particleaccelerators at major research institutions were out of service the year beforelast for repairs, so it is likely that the low number of articleswas due to the decline in availability of particle accelerators.

Which of the following, if true, most seriously underminesthe journalist’s argument?

(A) Every article based on experiments withparticle accelerators that was submitted for publication last year actually waspublished.
(B) The average time scientists must wait for access toa particle accelerator has declined over the last several years.
(C) The number of physics journals was the samelast year as in previous years.
(D) Particle accelerators can be used for more than onegroup of experiments in any given year.
(E) Recent changes inthe editorial policies of several physics journals have decreased thelikelihood that articles concerning particle-accelerator research will beaccepted for publication.

我100%理解OG解释上的逻辑，可是，想不通的是B和D
因为，如果记者的argument是说因为accelerator out of service 所以没有文章发表
那么B and D不是正好反驳了这一点，从而undermine了他的argument吗？
希望大N解答，非常感谢

同感！
我选了D...若是有一大群人研究的话，就不可能是
decline in availability of particle accelerators.

解释也这么说，然后这不就是undermine了嘛....

求牛牛们的解释~~~！

我认为bd两选项若成立就能说明发表的文章数目多了，而原题说文章数目变少了，这是不能改变的前提，所以bd是质疑原文研究意义，不选。
个人愚见

整个问题的前提是报告变少，如果B和D成立的时候，报告的数量并不一定会变少，这样子就和本来的前提矛盾了。

我做完OG逻辑的感觉是由A推出B，加强或者削弱都得从A,B的连接上入手。单说A，B好或者不好都不行。B,D只是针对A来说，一般都是不对的。

D is ok, but E is better. Since the passage does not mention anything between article number and group number. "More than one group" has nothing to do with the passage. E directly points out that there is a reason which causes the number of aritcles become lower. Choose E.
