Again, here's a diagram of an
a element for your reference:

Nesting just means putting one element inside of another element.
Now nest your existing
a element within a new
p element (just after the existing
h2 element) so that the surrounding paragraph says "View more cat photos", but where only "cat photos" is a link, and the rest of the text is plain text.
