标题: [求教]大全section c-15

Astronomers studying the newly discovered star say that it provides clues about our galaxy’s origin, that it may supply data about how fast our galaxy is expanding, and moreover it is perhaps the most distant star in the entire Milky Way.

(A) about how fast our galaxy is expanding, and moreover it is perhaps

(B) regarding the speed our galaxy expands at; moreover, they think it may be

(D) on the galaxy’s expansion rate and perhaps

(E) about how fast our galaxy is expanding, and that it is perhaps

答案：E

为什么B不可以？另外，我始终搞不太明白“；”对前后的两句句子有什么语法上的要求？请NN指点！

they think it may be是完整的句子不能用逗号直接连,应有连词

而这句话应是引导的宾语从句,用 that,与前面形成并列

这句话句型是say that ,that,and that

they think it may be并没有直接用逗号连啊，"...;moreover,they think it may be...",和之前的句子是用分号连接的，为什么不可以出一句完整的句子呢？

sorry ,我没看到分号.即使是分号.也不对.最后一句在逻辑上与第一句不是并列关系

能不能麻烦margaret1970具体讲一下，最后一句怎么和前面逻辑不并列法？谢谢！
