Final answer:
Hiro's situation is an example of internal conflict, which is a struggle taking place within an individual, unlike Carl's extrinsic motivation for mowing a yard for monetary compensation.
Step-by-step explanation:
Hiro's desire to spend all of his time participating in illegal bot fights instead of going to school can represent an internal conflict. An internal conflict is a struggle that takes place within an individual, where they are torn between different choices or desires. In comparison to Carl, who mows the yard each week for $20, which is an example of an extrinsic motivation since the motivation comes from an external reward, Hiro's situation is driven by internal factors such as his interests and passion. As such, the choice Hiro faces between his love for bot fighting and his responsibility to attend school demonstrates an internal battle.
