OG-11-86的2个混淆选项

moveon

86. 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 year. 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 .

B. The average time scientists must wait for access to a particle accelerator has decliened over the last several years.

D. Particle accelerators can be used for more than one group of experiments in any given year. 

我认为这2个选项错是因为无关.

可OG的解释是:

B. A decline in waiting time would seem to promote more articles about accelerator research being written and published, not fewer.

D. If the accelerators can be used for multiple experiments, then it is reasonable to expect more articles related to them, not fewer.

这2个解释不恰恰说明了可以weaken吗? 怎么这2个选项错又是错的呢?

我的思路有点乱了, 请大家指点一下吧.

研究结果的减少是事实，journalist的观点是粒子加速器少了，所以研究结果少了。要削弱他，应该用找出其他原因，说明不是因为加速器少了导致研究结果少了.上面的选项都在说会使研究结果增加的条件，当然无关拉。

谢谢Stzmy! 有点明白了.
