I was tasked with doing this "Before adding any new content, you should make use of a section element to separate the cat photos content from the future content.
Take your h2, comment, p, and anchor (a) elements and nest them in a section element. "
the code they are referring to in the exercise is these 4 lines
<h2>Cat Photos</h2>
<!-- TODO: Add link to cat photos -->

You must nest all 4 lines inside a new section element.
This means that you must write <section> on a line above the h2 line
and write </section> on a line below the anchor line
This effectively nests the 4 elements h2/p/comment/anchor into the section
