As a result of a supernova explosion, every human being on Earth was bombarded on February 23, 1987, by about 100 billion neutrinos; fortunately, neutrinos are harmless elementary particles that

are produced in nuclear reactions and that interact very weakly with matter.

(A) neutrinos are harmless elementary particles that are produced in nuclear reactions and that

(B) neutrinos, which are harmless, are elementary particles produced in nuclear reactions and

which

(C) neutrinos are harmless elementary particles produced in nuclear reactions and which

(D) these harmless elementary particles are produced in nuclear reactions, and neutrinos

(E) these elementary particles, harmless products of nuclear reactions, are neutrinos that
答案a。我选对了但是就是不明白笔记中的：(D) these在这里没有明确指代;

A中两个that并列修饰particles D和A比较改变意思了修饰发生变化修饰neutr.....了

我觉得还有另外一种解释就是原文的宾语变成了DE的主语就好像im a girl变成了girl is me
