Bit stuck on this one

I'm trying to figure out which arguments to pass in - the function takes name and mood - do I need to extract these from the array? And how do I include the second variable?

index.html 
<!DOCTYPE html>
<html lang="en">
  <head>
    <title> JavaScript Foundations: Objects</title>
    <style>
      html {
        background: #FAFAFA;
        font-family: sans-serif;
      }
    </style>
  </head>
  <body>
    <h1>JavaScript Foundations</h1>
    <h2>Objects: Call and Apply</h2>
    <script>
      var genericGreet = function(name, mood) {
        name = name || "you";
        mood = mood || "good";
        return "Hello " + name + ", my name is " + this.name +
          " and I am in a " + mood + " mood!";
      }

      var andrew = {
        name: "Andrew"
      }

      var args1 = ["Michael", "awesome", ":)"];

      var greeting = genericGreet(args1, andrew);
    </script>
  </body>
</html>

You need to call the apply method on genericGreeting... Remember the first argument you pass to apply() is the context, i.e. the value assigned to this. The second argument is an array.
