Directions (Q. Nos. 26-30) Read the passage carefully and choose the best answer to each question out of the four alternatives.
The common people have a way of laughing at their own misfortunes. They can also laugh at their oppressors. Satire became a habit with them while they groaned under the oppression of kings, priests and plutocrats. In contemporary India, the politician and the bureaucrat are the ones they take their revenge upon. There is much humour in Indian proverbs. Even the Gods are not spared. There is a special form of worship called ninda stuti, praise by dispraise.
Real humour in India, as elsewhere, is contained within the different languages and it is difficult for Indians of one region to understand the humour of another. India is also by tradition a class-ridden and hierarchical society. Excessive reverence is shown to elders and to those in authority, though this may be changing. Sons and daughters don’t usually joke with their parents and vice versa; a boss can’t afford to be seen in a mood of levity with his employees; the landlord wouldn’t dream of sharing a joke with his peasant labourers. The path to wit and humour is strewn with pitfalls. With Indian intellectuals, solemnity is a motto. Many of them wouldn’t be seen dead with a joke. And the higher they go in the cerebral scale, the drier they become.
