A和C都是对的吧
B中有连字符,数词就不能加S
D中hour后不用加连字符吧
Featuring a three-quarter walk-around with rear sundeck and large molded-in swim platform
we found the mile and three-quarter walk through the hardwood and mangroves to the bay to be quite pleasant

D. two---hour---walk

D
短字符连接表名词。

空白前面是不定冠词a，后面肯定要有个名词，所以不是选A就是选C，不可能选D。我认为A和C都正确

A. two--hour walk

A

C

a

c

选择A
理由：比如an eight-year-old boy 一个八岁的男孩
eight-year-old是一个合成词，作形容词，修饰boy(名词）；其中year不加s(那B错）
合成词的结构：‘数词+名词+形容词’（列 ）或
‘数词+名词’（two-hour),然后再修饰名词（walk做名词）
