9. Astronomers at the Palomar Observatory have discovered a distant supernova explosion, one that they believe is a type previously unknown to science.
(A) that they believe is
(B) that they believe it to be
(C) they believe that it is of
(D) they believe that is
(E) they believe to be of
In B and C, it and that it are intrusive and ungrammatical: the idiom is "believe x
to be y ”,B不对是因为that,it和one重复,还有缺少of,但不明白OG对B中it
的解释intrusive and ungrammatical, believe it to Y不可以吗?
