Final answer:
Maggie's offer to help by sharing notes with Jennifer, who broke her dominant hand, is best explained by the empathy-altruism hypothesis, which is based on Maggie's empathetic understanding of Jennifer's situation.
Step-by-step explanation:
The behavior of Maggie offering to help Jennifer by sharing her notes can best be explained by the empathy-altruism hypothesis. This hypothesis suggests that Maggie's willingness to help is motivated by the empathic concern she feels for Jennifer, having experienced a similar situation herself. Empathy is the ability to understand and share the feelings of another person, which can lead to altruistic behavior – acts done with the intention of helping someone else without expecting anything in return.
