What this skill is asking
Punctuation and sentence structure is the part of standard English that governs how clauses are joined and separated, and Ohio's State Test for English Language Arts II tests it in editing items and scores it under Conventions of Standard English on the extended response. Ohio's Learning Standards place this in the Language strand under Conventions. The most heavily tested points are the correct use of commas, semicolons, colons, and apostrophes, the legal ways to join two independent clauses, and the three classic sentence-boundary errors: the comma splice, the run-on, and the fragment. These errors are common in real writing, so fixing them improves both your editing-item score and the conventions score on your own essay. This page covers the main punctuation rules, the three ways to join independent clauses, and how to recognize and fix boundary errors.
Joining independent clauses
Knowing these three legal joins is the fastest way to handle a large share of editing items, because the wrong options are usually a comma splice or a run-on. When you see two complete thoughts pushed together, check the join: if it is only a comma or nothing at all, it needs fixing. This is the same boundary skill explored further in sentence boundaries and combining.
Fragments and how to fix them
Commas, semicolons, colons, and apostrophes
Try this
Q1. What are the three correct ways to join two independent clauses? [Recall]
- Cue. A comma plus a coordinating conjunction (and, but, so), a semicolon alone, or a period making two sentences. A comma alone is a splice; no punctuation is a run-on.
Q2. Fix this comma splice: "The bell rang, the students rushed out." [Short explanation]
- Cue. Any legal join works: "The bell rang, and the students rushed out" (comma plus conjunction), "The bell rang; the students rushed out" (semicolon), or "The bell rang. The students rushed out" (period). A comma alone is not allowed between two full clauses.

Ohio English II EOC (style)1 marksWhich sentence is punctuated correctly? (1) The rain stopped, we went outside. (2) The rain stopped we went outside. (3) The rain stopped, so we went outside. (4) The rain stopped; so we went outside.Show worked answer →
Answer: (3). Two independent clauses can be joined by a comma plus a coordinating conjunction ("so"), which (3) does correctly. Option (1) is a comma splice (a comma alone cannot join two independent clauses); (2) is a run-on with no punctuation; (4) misuses the semicolon before a conjunction.
The standard expects you to join independent clauses correctly. The legal joins are a comma plus a conjunction, a semicolon alone, or a period. Knowing those three options lets you fix splices and run-ons quickly.
Ohio English II EOC (style)1 marksWhich is a sentence fragment that should be revised? (1) The team practiced for hours. (2) Because the field was finally dry after a week of rain. (3) They won the match. (4) The coach smiled.Show worked answer →
Answer: (2). "Because the field was finally dry after a week of rain" is a dependent clause standing alone; it has no independent clause to complete it, so it is a fragment. A fragment is fixed by attaching it to a full sentence ("Because the field was finally dry, they practiced outside").
The other options are complete sentences with a subject and a verb. A subordinating word like "because," "although," or "when" at the start often signals a fragment if no main clause follows.
