GMAT 新题8－－9
9. According to the passage, one of the methods used to establish the properties of neutrinos was
(A) detection of photons
(B) observation of the interaction of neutrinos with gamma rays
(C) observation of neutrinos that were artificially created
(D) measurement of neutrinos that interacted with particles of seawater
(E) experiments with electromagnetic radiation
我不明白为什么D不对呢？文中也提到用seawater来detecte的啊，难道是measurement有问题吗？
有没有哪位正在看2772阅读的，能否给我个解释？ 谢谢 |
