Unity 2D Make An Object Disappear On Click

Hi i would like to have a script to make this object disappear. I am making a Jeopardy game for school and i would like to have it so I can click the question and it disappears, revealing an answer behind it. Im new at this so please bare with. I would also like to have it so with the first click it zooms onto the question, then deletes the object on a second click, revealing the question, and then after a third click it zooms out again, but I know this is hard, and involves multiple cameras so its not needed in the least bit. thanks for helping me out. here is what I have so far:

using UnityEngine; using System.Collections;

public class remove : MonoBehaviour {

 // Use this for initialization
 void start () {
     function OnMouseDown()
     {
         gameObject.active = false;
         //Destroy(gameObject);
         //renderer.enabled = false;
     }
 }
 }
