Each of the academic journals Thought and Ergo has a review committee to prevent misattributed quotations from appearing in its published articles. Nevertheless, about ten percent of the quotations in Thought's published articles are misattributed, whereas Ergo contains no misattributions. Ergo's committee is more effective, therefore, than Thought's at finding misattributed quotations.

The argument above assumes that

(A) most of the articles submitted to Thought for publication contain misattributed quotations
(B) there are at least some misattributed quotations in articles submitted to Ergo for publication
(C) the members of Ergo's committee are, on the whole, more knowledgeable than are the members of Thought's committee
(D) the number of misattributed quotations in a journal is an accurate measure of how carefully that journal is edited
(E) the authors who submit articles to Ergo for publication are more thorough in attributing quotations than are the authors who submit articles to Thought
