问题 Which of the following, if true, most logically completes the passage? Every fusion reaction releases neutrinos. To test a hypothesis about the frequency of fusion reactions in the Sun, physicists calculated the number of neutrinos the Sun would produce annually if the hypothesis were correct. From this they estimated how many neutrinos should pass through a particular location on Earth. The fact that far fewer neutrinos were counted than were predicted to pass through the location would seem to prove that the hypothesis is wrong, except that______.
选项 A、the physicists, using a different method for estimating how many neutrinos should reach the location, confirmed their original estimate
B、there are several competing hypotheses about the frequency of solar fusion reactions
C、there is not enough energy in the Sun to destroy a neutrino once it is released
D、the method used to count neutrinos detects no more than approximately ten percent of the neutrinos that pass through
E、neutrinos released in the fusion reactions of other stars also reach the Earth
答案 D
解析 本题为LSAT一道逻辑推理题的变形 作为完成段落考题，重点是读懂最后一句。 实际上，本题是让找一个选项说明这一事实不能证明该假设为错误，也就是找一个选项说明为什么点数到的、经过该地点的中子数要比预计的少得多。(D)说明用点数中子的方法仅发现了约不足10％的通过该地区的中子，解释了为什么点数到的比预计的要少，所以(D)正确。
