Final answer:
Harry uses his working memory's phonological loop to memorize the car's details by repeating them to himself, which is a rehearsing process within this component of Baddeley's working memory model.
Step-by-step explanation:
As Harry walks out of the supermarket, he sees his parked car get hit by another car. He tries to memorize the make, model, and license plate number of the other car. In this scenario, Harry is using his working memory's phonological loop. This component of Baddeley's working memory model is responsible for the temporary storage and manipulation of verbal and acoustic information, such as language. When Harry attempts to remember the car's details, he is likely repeating them to himself, which is a rehearsing process that keeps information in the phonological loop. The phonological loop allows individuals to maintain and work with verbal information for brief periods.
