This book will show the readers _can be used in other contexts.
A.how that they have observed B.that they have obsered
C.what they have observed D.how what they have observed
选那个,为什么选这个,为什么不选其他!

应该选C啊
1.这句句子的总体结构来看是个宾语从句而且是双宾,其中第一个宾语是readers,第二个宾语就是后面的这句宾语从句.show是谓语,宾语从句是what they have observed can be used in other contexts.
2.而这句宾语从句又是一句主语从句,what they have observed 是主语,后面的can是谓语.这样分析自然可以排除其他三个答案了.
