You are trying to convince your parents to send you to Europe. First, you ask them for a small favor (a bus ticket to a local city), hoping that later they will be more willing to send you on the longer trip. This technique is known as:

A. the fundamental attribution error.
B. the foot-in-the-door phenomenon.
C. motivated forgetting.

The answer is option (B) Foot-in-the-door phenomenon

Explanation:

Foot-in-the-door phenomenon is a technique of getting someone to grant or comply with a large request by initially making small or modest requests.  

The technique is based on the logic that if a respondent (the person being asked) can grant an initial small or modest request, then the respondent would be most likely to later grant a larger request that he/she (the respondent) would not have granted if asked outright (without being approached with small requests first).
