Answer:
foot-in-the-door technique
Explanation:
The foot-in-the-door technique is a persuasion tactic in which you get a person to comply with a large request by first asking them to comply with a smaller request.
So, initially you make a small request and once the person agrees to this they find it more difficult to refuse a bigger one.
For example, Ada made a smaller request by first-of-all asking Rob for a day worth of notes which he gave her before she then asked him for a week worth of notes which is a larger request.
The foot-in-the-door technique works on the principle of consistency . This means that as long as the request in consistent with or similar in nature to the original small request, the technique will work.
