A What waw as remarkable as the development of the compact disc

has been the use of the new techonology to revitalize

C Noless remarkable tnan the develipment of the compact disc has

been the use of the new techonology to revitalize

选C,lzm关于AC的区别解释的很模糊,为什么选C,A很对啊

Besides being wordy, the clauses beginning What was in A and The thing that was in B cause inconsistencies in verb tense: the use of the new technology cannot logically be described by both the present perfect has been and the past was. In B and D, developing the compact disc is not parallel to the use of new technology to revitalize... performances; in C, the best answer, the noun development is parallel to use. The phrases none the less... than in D and no less... as in E are unidiomatic; the correct form of expression, no less... than, appears in C, the best choice.
