Quiz works but having a problem with the display, not sure what is wrong

Hello, I was able to make the quizz fine but it keeps displaying in a strange way, the final print out is adding a blank list item after each answer in the correct and incorrect array, I'm not sure if it is just my browser or if it's something I actually did in the code. Is it showing up for everyone? And if it is, what part of the code is doing it?

var questions = [
[ "What number comes just before 1?", 0],
["What number is the lowest 3 didget number?", 100],
["Meaning of life?", 42]
]

var correctAnswers = 0;
var question;
var answer;
var response;
var HTML;

var correct = []
var incorrect = []

function print(message) {
  var outputDiv = document.getElementById('output');
  outputDiv.innerHTML=message;
}

function buildList(arr) {
var listHTML = '<ol>';
  for (var i = 0; i < arr.length; i += 1) {
  listHTML += '<li>' + arr[i] + '<li>';
  }
  listHTML += '</ol>';
  return listHTML;
}

for (var i = 0; i < questions.length; i += 1) {
question = questions[i][0];
answer = questions[i][1]
response = parseInt(prompt(question));
  if (response === answer) {
  correctAnswers += 1;
    correct.push(question);
  } else {
    incorrect.push(question);
    }
}

HTML ="You got " + correctAnswers + " answers right!";
HTML +='<h2>You got these questions correct:';
HTML += buildList(correct);
HTML +='<h2>You got these questions wrong<h2>'
HTML += buildList(incorrect);
print(HTML);

Thank you to everyone who contributes to answering my question :)

Also, your missing a semi-colon after 'answer = questions[i][1]' :)

Hi,

Looks like all you need to do is close your li tag here:

for (var i = 0; i < arr.length; i += 1) {
  listHTML += '<li>' + arr[i] + '</li>';
  }

I think that should sort your problem :)
