Inelegant solution

Javascript loops, arrays and objects Quiz Challenge

Here is my solution to Quiz challenge.

var qanda = [
["What is the capital of Illinois?", "springfield"],
["What is the last name of the governor of Illinois?", "rauner"],
["What is the Illinois State Bird", "cardinal"]
];
var rightAnswers = '';
var wrongAnswers = '';
var right = 0
var wrong = 0
function quiz() { 
for (var i = 0; i < qanda.length; i++) {
  var answer = prompt(qanda[i][0]);

  if (answer.toLowerCase() !== qanda[i][1]) {
  wrongAnswers += "<p>You got answer " +[i + 1]+ " wrong. The correct answer is " +qanda[i][1] + ".</p>";
    wrong += 1;
  } else {
    rightAnswers += "<p>You got answer " + [i + 1]+ " right! The correct answer is " +qanda[i][1] + ".</p>";
  right += 1;
  }

}
 print("<h2>You got " +right+ " answers right.</h2>" + rightAnswers);
 print("<h2>You got " +wrong+ " answers wrong.</h2>" + wrongAnswers);
}
function print(message) {
  document.write(message);
}

quiz();

This works but seems it could be improved on.
