单选题 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、 (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.

【正确答案】 B

【答案解析】[解析] 本题属于“B，A”类的假设，寻找假设应为“除了A以外没有其他原因来导致B”。而(B)恰恰讹明提交到Ergo发表的文章至少有一些错误引用的术语，从而说明除了Ergo更有效以外，没有诸如提交到Ergo发表的文章压根就没有错误的因素导致B，所以(B)正确。本题(D)易误选，但它不是推理成立的必要条件，即使错误引语的数目不是杂志编辑工作是否认真的一个标准。上面推理仍可以成立，因为上面的错误是用“百分比”来计算的，而两个杂志每年的期数和每期上发表的文章数目可能相差较远，所以(D)必然不对。通过本题，仔细体会，数字与比例的思维与感觉。
