You have the right idea.

Using querySelectorAll is a good idea, but you need a different selector. While links will likely contain an href property, that's not the easiest way to select them (and you wouldn't enclose the property name in quotes). But you don't want to select every link on the page anyway, just the ones in the nav element. So this might be a good place for a descendant selector. Remember how those work? You name the enclosing element, then a space, then the element(s) you want to select within it.

I'll bet you can get it now without an explicit spoiler.

I haven't been taught descendant selectors yet, I think this quiz must be used in multiple courses.

Selectors are more of a CSS concept. You'd find them in courses like CSS Basics and CSS Selectors. One of those should probably be listed as a prerequisite for this course.
