A jQuery selection acts on the HTML below, which selects the active menu item. What can you chain onto this selection to select the #main nav tag and add a class called "processed" to it?

<nav id="main">
  <ul>
    <li><a href="/" class="active">Home</a></li>
    <li><a href="/about">About</a></li>
  </ul>
</nav>

$('a.active').addClass('hover');
