23. A medical journal used a questionnaire survey to determine whether a particular change in its format would increase its readership. Sixty-two percent of those who returned the questionnaire supported that change. On the basis of this outcome, the decision was made to introduce the new format.
Which one of the following, if it were determined to be true, would provide the best evidence that the journal's decision will have the desired effect?
(A) Of the readers who received questionnires, 90 percent returned them.
(B) Other journals have based format changes on survey results.
(C) The percentage of surveyed readers who like the format change was almost the same as the percentage of the entire potential readership who would like format change.
(D) It was determined that the new format would be less costly than the old format.
(E) Ninety percent of the readers who were dissatisfied with the old format and only 50 percent of the readers who like the old format returned their questionnaires.
KEY. C
我觉得A 也有加强。因为如果发出的survey 收回的只有10%那么剩下90%有可能是不支持的。
是不是因为C加强的更多！ |
