<!-- Only change code above this line. -->

<div class="container-fluid">
  <h3 class="text-primary text-center">jQuery Playground</h3>
  <div class="row">
    <div class="col-xs-6">
      <div class="well" id="left-well">

Can you please explain what is the task that you need to do?

The error message you are getting says:

Only add one class with each of your three selectors.

In your code, you have:

 $("#target1").addClass("animated shake btn-primary")

I see three different classes for your #target1 selector. I see “animated”, “shake”, and “btn-primary”. Make 3 separate selectors using only one class for each.
