grampa simpson fell on the couch. upsetting his sleeping cat.

Explanation:

The second sentence "Upsetting his sleeping cat." is a dependent clause (a participial phrase) that cannot stand alone as a complete sentence. It should be connected to the independent clause it modifies. We can replace the period with a comma to correctly join the phrase to the main clause, creating a grammatically complete sentence.

Answer:

Grampa Simpson fell on the couch, upsetting his sleeping cat.
