Many ____ have developed as people have found ___how to sing in diffferent ways
A:music B:musics C:kind of music D:kinds of music
A:out B:over C:off d:through
答
D， A
答
Many -kinds of music- have developed as people have found -out- how to sing in different ways.
答
D,A
music不可数所以不能直接跟many.而many修饰的必然是可数的复数形式,因此是kinds而不是kind.
find out是个固定搭配的词组
