LOL! Quite frankly, who cares? With only 85 rows being scanned, MySQL will do it all in memory anyway.
But it looks to me like you don't have a PRIMARY KEY on the NEWS table, and that's a mistake, for sure. (If you have one, MySQL has decided not to bother using it, because of finding only 85 eligible rows, which makes sense.)
And then on the pages table you could probably use two indexes: One for the column (page_id?) that references the news table and one for the column (id?) that references the comments table.
