three days' trip 和 a three days' trip
1 three days' trip
2 a three days' trip
3 a three-day trip

都对的啊
像three-day这样的组合词可以做形容词，后面就不用加s了
如果一定要选的话就选2，3吧，因为第一个没冠词
好像是楼上的翻译 哈哈

2 a three days' trip 是正确答案
答
3 吧。一般都是数量-名词单数作定语的

all above
but the first needs an art. .so if you say that only two are right, they must be the last two

1and 3
