Critical Reasoning

The soaring prices of scholarly and scientific journals have forced academic libraries
used only by academic researchers to drastically reduce their list of subscriptions.
Some have suggested that in each academic discipline subscription decisions should
be determined solely by a journal's usefulness in that discipline, measured by the
frequency with which it is cited in published writings by researchers in the
discipline.

Which one of the following, if true, most seriously calls into question the suggestion
described above?

(A) The non-academic readership of a scholarly or scientific journal can be
accurately gauged by the number of times articles appearing in it are cited in
daily newspapers and popular magazines.
(B) The average length of a journal article in some sciences, such as physics, i s less
than half the average length of a journal article in some other academic
disciplines, such as history.
(C) The increasingly expensive scholarly journals are less and less likely to be
available to the general public from non-academic public libraries.
(D) Researchers often will not cite a journal article that has influenced their work if
they think that the journal in which it appears is not highly regarded by the
leading researchers in the mainstream of the discipline
(E) In some academic disciplines, controversies which begin in the pages of one
journal spill over into articles in other journals that are widely read by
researchers in the discipline.
