MySQL随机限制选择与表连接

我有一个简单的数据库（见图），我想随机检索10个问题及其所有答案（每个问题2-4个答案）。我尝试了多次查询，但似乎都不正确

我尝试过的事情：

SELECT qa.Answerid,qa.Questionid
FROM question_answer as qa
JOIN (SELECT q.Questionid FROM question q ORDER BY rand() LIMIT 10)
WHERE qa.Questionid = q.Questionid

select *
From question q,question_answer qa,answer a 
where qa.Questionid=q.Questionid and qa.Answerid=a.Answerid
ORDER BY rand() LIMIT 10

我需要如下结果：

AnswerId         QuestionId       ...        ...        ...

最多10个随机问题ID，答案ID的数量将根据10个随机问题的答案数量而变化

感谢您的帮助。
