This page first loads 4 words into the options DIVs via Ajax and then randomizes the correct answer with the following function, passing the D

Answer 1

return( temp%2 ); Leaves you with only 0 or 1

Try using return( temp%4 ); Which would leave you with 0,1,2,3

Although I am not sure what the modulus is for.
This will get you a random number between 0 and 3:

Math.floor(Math.random()*4)

So all you need to do is:

var random = function(r){
    r.children().sort(function(a,b){
        return Math.floor(Math.random()*4);
    }).appendTo(r);            
};
