13. In 1712 the government of Country Y appointed a censor to prohibit the publication of any book critical of Country Y’s government; all new books legally published in the country after 1712 were approved by a censor. Under the first censor, one half of the book manuscripts submitted to the censor were not approved for publication. Under the next censor, only one quarter of the book manuscripts submitted were not approved, but the number of book manuscripts that were approved was the same under both censors. If the statements in the passage are true, which one of the following can be properly concluded from them?
A. More books critical of Country Y’s governments were published before the appointment of the first censor than after it. B. The first censor and the second censor prohibited the publication of the same number of book manuscripts. C. More book manuscripts were submitted for approval to the first censor than to the second. D. The second censor allowed some book manuscripts to the published that the first censor would have considered critical of Country Y’s government. E. The number of writers who wrote unpublished manuscripts was greater under the first censor than under the second.
23. On a certainday, nine scheduled flights on Swift Airlines were canceled. Ordinarily, acancellation is due to mechanical problems with the airplane scheduled for acertain flight. However, since it is unlikely that Swift would have themechanical problems with more than one or two scheduled flights on a singleday, some of the nine cancellations were probably due to something else.
The argument depends on which one of the following assumptions?
A. More than one or two airplaneswere scheduled for the nine canceled flights. B. Swift Airlines has fewer mechanical problems than doother airlines of the same size. C. Each of the canceled flightswould have been longer than the average flight on Swift Airlines. D. Swift Airlines had never beforecanceled more than one or two scheduled flights on a single day. E. All of the airplanes scheduledfor the canceled flights are based at the same airport.
第二个我觉得题目说的有点问题。如果说是unlikely.....more than one or two airplaneson a single day....而不是 scheduled flights 。。即不可能多于一架或两架的飞机一起有技术问题，那么A取非，即九个航班里，有多于两架的飞机。。。。
