Read the passage below and answer the questions that follow:-

Arun was an intelligent smart and friendly boy who was very popular amongst his peers. He often did not carry his lunch box to school but would eat from his classmates tiffins, on the sly, under the pretext of checking their bags for bringing mobile phones. He would often regret his behaviour at home but was unable to resist his temptation for interesting food and a little prank. On one such day Arun founds Rs. 500/- in a friend's bag. Although he was tempted to take the money to buy food from the canteen, he did not take it, as he understood very well that it would be going too far. Stealing was something his conscience would never allow.
