Nothing is happening? No prompts or anything.

var questions[
  ["What color is an Apple", "Red"],
  ["What color is an Blueberry", "Blue"],
  ["What color is an Pumpkin", "Orange"]
];
var correctAnswer = 0;
var question;
var answer;
var response;
var html;
function print(message) {
  document.write(message);
}

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;
  }
}

html= "You got " + correctAnswers + " question(s) right.";
print(html);

There were just some typos. 

// You were missing the "=" in the declaration.
var questions = [
  ["What color is an Apple", "Red"],
  ["What color is an Blueberry", "Blue"],
  ["What color is an Pumpkin", "Orange"]
];

// Defined as "correctAnswer", but used in plural form, just a simple typo. 
var correctAnswer = 0;
var question;
var answer;
var response;
var html;
function print(message) {
  document.write(message);
}

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

html= "You got " + correctAnswer + " question(s) right.";
print(html);
