Answer

Explanation:

To correct the text, we need to use serial commas (Oxford commas) to separate the items in the list "primitive buildings, tombs, and stone walls". This is because the note specifies that serial commas are not optional here. So we insert commas after "buildings" and after "tombs" to properly separate the list items.
