请帮忙看一下这两个英语句子
Mr Johnson and his______son don't always understand each other.
A.older B.elder C.the oldest D.the eldest
What I would do is to go___________________.
A.really quietly somewhere
B.somewhere quietly really
C.really quiet somewhere
D.somewhere really quiet
其中第二句句子麻烦您说出语法的理由.

1.B
因为older是较老的,elder是较年长的,C和D加上the不是形容词了,和其后修饰的名词son不符
2.D
go somewhere是固定搭配,really quiet作somewhere的定语,其中really为副词,后面应该跟形容词.
