以下是引用siebel在2003-7-19 22:33:00的发言: 203. 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? (A) Every article based on experiments with particle accelerators that was submitted for publication last year actually was published. (B) The average time scientists must wait for access to a particle accelerator has declined over the last several years. (C) The number of physics journals was the same last year as in previous years. (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 physics journals have decreased the likelihood that articles concerning particle-accelerator research will be accepted for publication.
这题重新看了一遍,答案E没有问题,是属于他因该果(few articles)的weaken A是属于排除他因-->没有没有发表的articles,所以support C也是属于排除他因-->发表的数量与前年一样,所以并不是availability减少的关系,support 但对于B,D觉得无法理解 B:根据OG的解释-->减少等待时间是会造成增加articles,这样不是他因非果(more articles),weaken了吗? D:也是根据OG的解释-->使用增加会造成增加articles,这样也不是他因非果(more articles),weaken了吗? 是不是因为B跟D都是产生more articles,所以不是most seriously undermine?? 请nn指点............. |
