E.they believe to be of
我对这个答案选出来的方法没有疑问,但是有一个不确定的地方是逗号后面的部分如果 将所有代替和省略的词复位的话是不是: they believe a distant supernova explosion(one指代的) to be one of a type unknown to science.
还有一个题 30.What was as remarkable as the development of the compact disc has been the use of the new technology to revitalize, in better sound than was ever before possible, some of the classic recorded performances of the pre-LP era.
C.No less remarkable than the development of the compact disc
