Two Sentences, One Relationship
A student is revising a paragraph in a placement essay about part-time work. The draft contains this sentence: 'Many students work twenty hours a week, they still struggle to cover tuition.' Later in the same paragraph: 'The job teaches time management, it also consumes the hours students need for study.' A peer reviewer marked both sentences 'run-on' without further comment. The student wants to fix them but is unsure whether the problem is the same in both, and is worried about over-correcting by chopping every sentence into short fragments. The paragraph must stay under 120 words and currently sits at 108.
1. Diagnose the two sentences. Are they the same kind of error, and what are the available repairs for each?

Both are comma splices-two independent clauses joined by only a comma. The structural problem is identical, but the logical relationship differs, and that should drive the repair.
Sentence 1 (work twenty hours / still struggle) sets up a contrast. Repairs:
- Semicolon: ...twenty hours a week; they still struggle...
- Conjunction: ...twenty hours a week, yet they still struggle...
- Split: Many students work twenty hours a week. They still struggle...
Sentence 2 (teaches time management / also consumes hours) sets up an addition of a counterweight. Repairs:
- ...teaches time management, but it also consumes...
- ...teaches time management; it also consumes...
Because the relations differ, using the same fix in both places (e.g., two semicolons) would be grammatically fine but would flatten the contrast in sentence 1 and the balance in sentence 2.
2. The student fears fragmenting the paragraph. Given the 120-word cap and the current 108 words, what should guide the choice among repairs?

Word count is a real constraint here, and it favors the semicolon or a coordinating conjunction over splitting into two sentences.
- Splitting sentence 1 into two sentences adds words (a new subject and verb, plus a capital) and two sentence boundaries in a 108-word paragraph that can afford only 12 more.
- A semicolon or a comma-plus-conjunction changes no content words and keeps the paragraph's rhythm.
A workable revision pass: use yet in sentence 1 to mark the contrast, and but in sentence 2 to mark the counterweight. That adds roughly two words, keeps both clauses intact, and leaves room under the cap.
The broader principle: a fragment problem and a run-on problem are opposite failures, so fixing run-ons by splitting everything can create the error the student fears. Choose the repair that matches the logical relation and the space available.
