Final answer:
The described situation is an example of the foot-in-the-door technique, a persuasion strategy that starts with small requests and leads to larger ones.
Step-by-step explanation:
The scenario described is an example of the foot-in-the-door technique. This type of persuasion starts by getting someone to agree to a small request, such as carrying supplies, and then gradually escalates to larger favors, like joining a weekly tutoring program. This technique relies on the principle of consistency; once we agree to a small request, we're more likely to comply with larger requests to maintain a consistent image of ourselves. The foot-in-the-door technique is shown to be effective because it subtly changes people's attitude, ideas, and behaviors over time.
