Turn a teacher's three-word margin comments into a concrete revision checklist you can actually act on

Help me turn vague grading comments on my paper into an actual revision checklist I can act on, since the comments alone don't tell me what specifically to change.

ASSIGNMENT AND WHAT IT'S GRADED ON
A 5-paragraph argumentative essay on whether social media should be regulated for minors, graded on thesis clarity, evidence use, and counterargument handling.

MY TEACHER'S ACTUAL COMMENTS (verbatim)
'Unclear' (next to paragraph 2 topic sentence), 'needs more support' (next to paragraph 3), 'so what?' (in the margin of the conclusion), 'weak' (circled next to the thesis).

RELEVANT EXCERPT FROM MY PAPER EACH COMMENT WAS ATTACHED TO
Thesis: 'Social media has both good and bad effects on minors.' Paragraph 2 topic sentence: 'Another effect is on mental health.' Paragraph 3: cites one statistic with no explanation of where it's from.

For each comment, do three things: state the most likely specific meaning behind it given where in my paper it was attached and what the assignment is graded on; if the comment is genuinely ambiguous between two plausible meanings, say both and tell me which is more likely given context, rather than picking silently; and give one concrete action I can take to address it, specific enough that I'd know whether I actually did it — not "be clearer" but the actual sentence-level or paragraph-level change to make. Where a comment references something that needs outside verification, like a factual claim or a citation format rule, tell me to check the actual assignment guidelines or a citation manual rather than asserting a rule as if you know my teacher's specific standard.

If several comments seem to point at one underlying, recurring issue rather than several separate problems, say so and name the single root cause — a student fixing five symptoms individually often still misses the one pattern the teacher was actually flagging across the whole paper.

Output as a checklist: one line per comment with the likely meaning and the concrete action, followed by a short note at the end naming any recurring pattern across comments and the one change that would fix all of them at once.
