Journalist: In physics journals, the number of articles reporting the results of experiments involving particle accelerators was lower last year than it had been in previous years. Several of the particle accelerators at major research institutions were out of service the year before last for repairs, so it is likely that the low number of articles was due to the decline in availability of particle accelerators. Which of the following, if true, most seriously undermines the journalist's argument? D. Particle accelerators can be used for more than one group of experiments in any given year E. Recent changes in the editorial policies of several phsics journals have decreased the likelihood that articles concerning particle- accelerator research will be accepted for publication OG解释说D更加显示了article的数量会增加的可能性,E是正确答案,属于它因削弱- 但我觉得不好,因为E说decreased the likelihood,那decrease的程度我们不知道,有可能小有可能大,如果可能性decrease程度小的话,就不能削弱了,有可能虽然可能性减少了,但是article减少数量较前几年差别不大,而真正article大量减少的原因则还是有可能由原文中out of service引起的 D正好说明文章减少不是由accelerators数量减少造成的(因为实际article的数量减少了),而是有它因大量减少了article的数量 - 即本来文章数目是不会减少(或者反而增多),但由于另外的原因,导致大量文章未被发表(比如相关科研人员数目减少之类) 请大家帮帮忙,这道题该从什么角度考虑呢,谢谢! |
