Final answer:
Melissa is using ingratiation to influence her roommate Kelly to provide a ride to the airport by complimenting and praising her.
Step-by-step explanation:
Melissa is using ingratiation to get her ride. Ingratiation is a psychological technique in which an individual attempts to influence another person by becoming more likable to their target. By complimenting Kelly on her appearance, acknowledging her contribution to the cleanliness of the apartment, and praising her sense of humor, Melissa is engaging in behaviors that are meant to make Kelly feel appreciated and positive about her, thereby increasing the likelihood that Kelly will be disposed to do Melissa a favor, in this case, providing a ride to the airport.
