This question is just asking you to select all of the links inside of the navigation and assign them to the variable navigationLinks.

this can be done like this 

let navigationLinks = document.querySelectorAll('nav a');

and the next questions are asking pretty much the same things for other elements hope this helps

Why can you not just type 'nav'? Why is 'nav a' required?

They're asking for links which are defined by the anchor (<a>) tags, Braeden Long. If you use 'nav' you'd be targeting the <nav> element, which is the parent for a lot of elements (ul, li, a...) which will return a different behavior.
