标题: 求解。PREP 1-42

42. (26647-!-item-!-188;#058&002738)

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

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

(E) these elementary particles, harmless products of nuclear reactions, are neutrinos that

A和E如何觉得哪个更好？

有搜索过前人的解答（http://forum.chasedream.com/dispbbs.asp?BoardID=23&replyID=2440360&id=262961&skin=0 七楼），认为“E选将原来的主语neutrinos变为了particles”。而我认为，由于代入E选项后，整个句子在these前只出现过一个复数名词neutrinos，these的指代很明确，哪E选项为什么比A差呢？
