1.The musical comedy Oklahoma! did much to expand the potential of the musical stage, and it encouraged others to attempt......

(a)original themes

(b)to original themes

(c)that were original themes

(d)how original themes

这题为什么选A啊?

真老九

attempt是及物动词，后面可以接名词，也可以接to do sth的形式，但是b选项不是to do的结构。因此选A
