can someone explain to me how to select the correct links

I am not sure how to do this. I've tried using MDN and watching the video over and I am just not understanding the concept. Hope you can help, thanks!!

js/app.js 
let navigationLinks= document.querySelectorAll('nav a');
let galleryLinks= document.querySelectorAll(' ul');
let footerImages;

Question was : Next, select all links inside the unordered list with the ID gallery and assign them to the variable galleryLinks.

For this you need to use .querySelectorAll() .First time you add the ID with #idName then make an empty space and select what childrent of the parent with that id wanna select. In this example " document.querySelectorAll('#gallery a') " you select all children with a tag that are childrent to the element with id gallery from your html file.

let navigationLinks= document.querySelectorAll('nav a');
let galleryLinks= document.querySelectorAll('#gallery a');
let footerImages;
