Question

[1]. Read the following passage carefully:

Passage: "A travelling theatre troupe moved from village to village in a bullock cart loaded with costumes, drums and painted curtains. Its leader, Mohan, was an old actor who believed that theatre should teach without preaching. The troupe performed the story of a farmer who saved his village from drought by sharing water, not by fighting over it. A boy named Chotu joined the troupe to play the drum. At first he only made noise. Mohan taught him to listen to the actors' words and strike the drum at the right moment. Slowly, Chotu understood that music in a play is like salt in food. Too much spoils it, too little makes it dull. When the troupe performed in a large fair, the audience wept at the farmer's sacrifice and cheered his wisdom. Chotu realised that a play can change hearts where long speeches fail, because people remember a story long after they forget advice." What is the main idea of the passage?
