Question

Explanation:

Step1: Identify the dependent clause

The phrase "Sitting in the movie theater" is a dependent clause (a participial phrase acting as an adverbial modifier) that introduces the main clause "Patrick Star realized he had forgotten to buy popcorn."

Step2: Add a comma after the dependent clause

To separate the introductory dependent clause from the main clause for clarity and correct punctuation, we add a comma after "theater".

Sitting in the movie theater, Patrick Star realized he had forgotten to buy popcorn.
