Personal Response Task.

Human beings are willing to do good to others because:-

1) They hope that help will be rendered to them when they need it, by the people they had helped in the first place.

2) Helping others makes them happy and allows them to lead more meaningful lives.

3) They are "social animals" and it's only natural for them to want to feel closer to one another, which can be achieved through interaction, or in this case, through doing good to others.
