Answer 2

Let me know if this is what you are trying to get at.

var Question = function(question,answer,correct) {
this.question = question;
this.answer = answer;
this. correct = correct;
}

var question1 = new Question("Is the sky blue","Yes");

Question.prototype.displayQuestion = this. Question;

console.log(question1);
