Magazine Publisher:  Our magazine does not have a liberal bias.  It is true that when a book review we had commissioned last year turned out to express distinctly conservative views, we did not publish it until we had also obtained a second review that took a strongly liberal position.  Clearly, however, our actions demonstrate not a bias in favor of liberal views but rather a commitment to a balanced presentation of diverse opinions.

 

Determining which of the following would be most useful in evaluating the cogency of the magazine publisher’s response?

 

1. Whether any other magazines in which the book was reviewed carried more than one review of the book
2. Whether the magazine publishes unsolicited book reviews as well as those that it has commissioned
3. Whether in the event that a first review commissioned by the magazine takes a clearly liberal position the magazine would make any efforts to obtain further reviews
4. Whether the book that was the subject of the two reviews was itself written from a clearly conservative or a clearly liberal point of view
5. Whether most of the readers of the magazine regularly read the book reviews that the magazine publishes

答案是C,我怎么觉着是D啊...
