Question

——Finished?——No,I have __three question.A.another B.other
为什么选A?B为什么不行?
——No,I have __three questions
不好意思打错了，这才是正确的

Answer 1

another:one more person or thing or an extra amount
other:1)as well as the thing or person already mentioned 2)used at the end of a list to show that there are more things,without being exact about what they are
通过以上解释,another是说明多出来的东西或人.而other,表示已经提到过的东西或人,或者说还有其他东西,但是这个东西不是指明的.
three questions,指明的多出的三个问题,所以不能用other,应该用another.
