标题: [求助]OG 203
203. 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.


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


(A) Every article based on experiments with particle accelerators that was submitted for publication last year actually was published.


(B) The average time scientists must wait for access to a particle accelerator has declined over the last several years.


(C) The number of physics journals was the same last year as in previous years.


(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.



为什么选项D不对呢?我觉得D和E都对,为什么选E而排除D 呢?

ChoiceD does not weaken the journalist’s argument: even if accelerators can be used for several experiments, a reduction in the number of accelerators is likely to lead to a reduction in the number of experiments. E strongly supports an alternative explanation for the decline:
