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.

Its a clean E, giving an alternate cause for the decline in number of articles published.

Clearly answer should be E as this provides alternate reason for decrease in reports

+1 for E,but D also seems tempting as it implies that there was not actually any dearth of particle accelerators to do the experiment and publish the article thus there may be another reason for the low number of articles.

what threw me off was the present/future tense of the answer E - "recent changes" and "will be accepted for publication", considering that the question talks about "last year". I automatically assumed that these recent changes couldn't have any effect on articles published last year. Has anyone else noticed it?

The best way to answer this is to determine the parts of the argument:

Premise: 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.

Premise: Several of the particle accelerators at major research institutions were out of service the year before last for repairs.

Conclusion: It is likely that the low number of articles was due to the decline in availability of particle accelerators.

In here we could see that causation. Simply put: Out of service particle accelerators ----> Low number of articles

The question is asking us to undermine (weaken) the argument. We know that one of the ways to weaken an argument is to introduce another cause to the intended effect.

This is the reason why D is the answer. D provides us another cause that 'caused' the effect. The importance of determining the parts of the argument is that it helps us determine which among the answer choices 'destroys' the conclusion. In this case, D totally demolishes it.

E must be the answer.

Conclusion: 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.


Choice D tells us that particle accelerators can be more effectively used to publish more number of articles. But it is not what the conclusion of the argument is concerned about. The right answer must find an alternative reason for the low number of articles.
