Multiple answers to question

Me again, with a different problem...

How do you check for correct answers to a question, when there are four correct answers from a possible six. The answers can be answered in any order, and each answer can only be used once.

Want to avoid having to do a manual check along the lines of:

Actionscript Code:

if (answered[0] == answer1) {
        game_stage = CORRECT_ANSWER;
    }
if (answered[0] == answer1 && answered[1] == answer2) {
        game_stage = CORRECT_ANSWER;
    }

as this quickly gets inefficient and messy...

Any smart ideas, very greatly appreciated.

Thanks indeed!

array(s) with the questions, correct yes or no flag, and a been used flag?
