People who listen to certain recordings of music are in danger of being unduly influenced by spoken messages that have been recorded backwards on the records or tapes.

A consequence of the view above is that

(A) the spoken messages must be louder than the music on the recordings

(B) backwards messages can be added to a recording while still preserving all of the musical qualities of the recorded performance

(C) the recordings on which such messages appear are chosen for this purpose either because they are especially popular or because they introduce a trancelike state

(D) if such messages must be comprehended to exert influence, then people must be able to comprehend spoken messages recorded backwards

(E) when people listen to recorded music, they pay full attention to the music as it plays

选什么？

这题关键是阅读

D翻译成中文你肯定理解

如果听音乐的人只有在听懂了这些杂音的基础上才会被杂音所影响 那么他们一定能听懂（因为前面题设说他们已经被杂音所影响了）

翻译的有点awkward 意思是这样的

在细想一下就通了
