In the "The data for each resolution" section, the screenshot preview of the list of symbols and urls that are children of the year 2016 parent page has URLs that appear to be different from those embedded in the current version of the UN Security Council page. Whereas the lesson shows URLs of the structure http://www.un.org/en/ga/search/view_doc.asp?symbol=S/RES/2336(2016), the parent page now has http://undocs.org/S/RES/2336(2016).
Note that both links work, so this doesn't affect anything other than what a user might expect to see in a data preview or export table.
