Re-read the whole file from top to bottom once all other sub-questions are done.
Check every opening tag has a matching closing tag, and that tags close in the reverse order they opened (innermost first) — see the minimum-structure and text-formatting notes.
Pay special attention to tags you edited for 6.2, 6.4 and 6.7, since a forgotten closing
</font>or</td>is the most common way to lose this mark.
Why this earns the marks
this mark is awarded once for the document as a whole rather than for any single instruction, so it rewards general HTML hygiene: matched pairs and correct nesting order across every tag you touched, not just the ones named in 6.1–6.7. It exists because every other sub-question in this question asks you to edit markup that's already partly broken, which means there's real risk of forgetting a closing tag or nesting something incorrectly while fixing a different, unrelated fault nearby — this mark specifically checks that your edits didn't leave a new structural problem behind, on top of fixing the ones you were explicitly asked to fix.
