问题 It can be inferred from Paragraph 1 that the" initial findings" of Dr. Conrad and Louis are ______.
According to the text, Neutrinos are kinds of particles that ______.

选项 A、are numerous and stable.
B、have no electric charge.
C、are short-lived matter.
D、are small in amount.

答案C

解析 为细节理解题。本题主要信息在第3段,但本段只是Los Alamos实验中发现的性质,有些可能是有局限性的,比如:neutrino呈中性就是错误的。数量庞大,不稳定,很快衰竭等等特性是正确的,这样只有C是正确的。
