How to archive different pages that don’t have a different URL

bookmarkswebsite

I was trying to archive "Academia Guatemalteca de la Lengua. Breve historia" and "Academia Guatemalteca de la Lengua. Los académicos", but I discovered that both pages have the same URL; if I archive the URL and try to click "Los académicos" it will try to load it as a different web page entirely, so I need to archive those two links separately. How do I do it?
