Is it possible to refactor my code further?

var questions = [
  ["How many states are in the United States?", 50], 
  ["How many continents are there?", 7], 
  ["How many legs does an insect have?", 6]
];
var correctQuestion = []; // Initializing a single array to hold question(s) answered correctly
var wrongQuestion = []; // Initializing a single array to hold question(s) answered wrong
var correct = 0; // Number of correct answer(s)
var wrong = 0; // Number of wrong answer(s)
var answer; // Hold the user's input

// Print the list of question
function printResult(arrayQuestion) {
  var listHTML = '<ol>';
  for (var i = 0; i < arrayQuestion.length; i += 1) {
    listHTML += '<li>' + arrayQuestion[i] + '</li>';
  }
  listHTML += '</ol>';
  print(listHTML);
}

function print(message) {
  document.write(message);
}

function quiz(question) {
  for (var i = 0; i < question.length; i += 1) {
    answer = parseInt(prompt(question[i][0])); // Ask user for input and parse it to an integer

    // Check whether the answer is correct/wrong, increment its respective counter by 1
    // and store the question by pushing it to the end of the single array
    if (answer === question[i][1]) {
      correctQuestion.push(question[i][0]);
      correct += 1;
    } else {
      wrongQuestion.push(question[i][0]);
      wrong += 1;
    }
  }

  print('You got ' + correct + ' question(s) right.');

  // If correct is more than 0, the code inside will be executed; otherwise move to the next if statement
  if (correct > 0) {
    print('<h2>You got these question(s) correct:</h2>');
    printResult(correctQuestion);
  }

  // This if statement will only be executed if wrong is more than 0
  if (wrong > 0) {
    print('<h2>You got these question(s) wrong:</h2>');
    printResult(wrongQuestion);
  }
}

quiz(questions); // Call the function quiz
