Which of these sentences contains a run-on?

• A. I went to the store I bought milk.
• B. She loves to read, and she also enjoys writing.
• C. He went sailing, then caught fish.
• D. They will attend the meeting next week.

Answer: (A)

The sentence "I went to the store I bought milk." demonstrates a run-on sentence because it improperly combines two independent clauses without a coordinating conjunction or appropriate punctuation. Each clause could stand alone as a complete sentence, but here they are fused together in a way that makes the structure grammatically incorrect. In contrast, the other examples effectively utilize punctuation or conjunctions to clearly separate or connect thoughts. The second option uses a conjunction to link two related clauses, while the third one effectively employs a comma to separate two independent actions. The fourth choice is a straightforward declarative sentence that correctly conveys one complete thought. Thus, the correction and identification of run-ons hinge on recognizing how independent clauses should appropriately connect within a sentence.
