Where do you think one sentence ends and the next one begins?
How would you correct it?
Yes, the sentence "Martha moans and groans upon getting in the morning she sounds like a crazy woman" is a run-on sentence because it combines two independent clauses without appropriate punctuation or conjunction.
To correct this run-on sentence, you can add a coordinating conjunction (such as "and") between the two independent clauses, or you can separate them into two separate sentences. Here are two possible corrections:
1. Martha moans and groans upon getting in the morning, and she sounds like a crazy woman.
2. Martha moans and groans upon getting in the morning. She sounds like a crazy woman.
In these corrected versions, the two independent clauses are properly separated either by a coordinating conjunction or by ending one clause and beginning a new sentence.
