What do you guys think of my code?

function main(questionList) {
    for (var i = 0; i < questionList.length; i += 1) {
        response = prompt(questionList[i][0]);
        if (response.toLowerCase() === questionList[i][1]) {
            rightAnswers.push(questionList[i][0]);
        } else {
            wrongAnswers.push(questionList[i][0]);
        }
    }
}

/* Takes an argument for the list that you want to print out
along with a string determining if it's right or wrong
which inserts it into the string instead of writing it twice*/
function printEach(list, rightWrong) {
    document.write('<hr>');
    document.write('<h1>You got the following ' 
        + rightWrong + '! (' + list.length + ')</h1>');
    for (var i = 0; i < list.length; i += 1) {
        document.write('<p>' + list[i] + '</p>');
    }
}

/*Takes the above function and uses it on both arrays
to pass arguments and print them out*/
function printOut() {
    printEach(rightAnswers, "right");
    printEach(wrongAnswers, "wrong");
}

//These are the questions and answers
var questionsAnswers = [
    ["What is my last name?", "rodrigues"],
    ['What is my favorite color?', 'black'],
    ['What is my college major?', 'computer science'],
];

//Setting up arrays
var rightAnswers = [];
var wrongAnswers = [];

/*Running the main function in order to ask the questions, 
then push whether the answer is correct or not to another array*/
main(questionsAnswers);
printOut();
