It says that there is only one link, not 3.

There are a couple of ways to do this task: one is to chain selector methods together to pick the nav
and then pick the links (a) within it; and the other is to use a different kind of selector method that allows CSS-style combined selectors such as a descendant selector.

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