Which of the following selections contains a run-on? If none of the selections contains a run-on, select "Correct."

(a) Everyone praised Matthew for his will power.

(b) He quit smoking five years ago, he still craves a cigarette from time to time.

(c) Addictions are hard to break

(d) Correct

I think they are all correct sentences but I'm starting to question if (c) is a run-on.

b is the correct answer. it should be put into 2 sentences

I'm sorry, I put that I was doubting (c) but ment to put (b).

Thank You

B has the run-on, yes.

To identify if there is a run-on sentence, we need to understand what a run-on sentence is. A run-on sentence occurs when two or more independent clauses are joined together without appropriate punctuation or conjunctions.

Let's examine each option:

(a) "Everyone praised Matthew for his willpower."

This sentence is grammatically correct, as it consists of a single independent clause and does not contain any conjunctions.

(b) "He quit smoking five years ago, he still craves a cigarette from time to time."

In this case, we have two independent clauses joined by a comma. This is an example of a run-on sentence. A correction could be made by adding a coordinating conjunction (e.g., "but") or replacing the comma with a period or semicolon.

(c) "Addictions are hard to break."

This sentence consists of a single independent clause and is grammatically correct. It is not a run-on sentence.

(d) "Correct."

This option is not a sentence but a single word, so we can disregard it for the purpose of identifying run-on sentences.

Therefore, the correct answer is (b), as it contains a run-on sentence.
