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.

d无关。
b等待的时间少了，文章因应该多，发表的应该多。但和argument无关。而且，b说has declined over the last several years. 而题干里面讲的是去年和前些年的一些区别。

这道题我也错了，我之前选的是b

小耳蛇蛇

B和D直接削弱结论为何不可？
