Section 4: Reading Comprehension (English)

(Read the given passage and answer the questions that follow.)

Passage:

A passage led to the backyard, where a well and a lavatory under a large tamarind tree served the needs of the motley tenants of the ancient house in Vinayak Mudali Street; the owner of the property, by partitioning and fragmenting all the available space, had managed to create an illusion of shelter and privacy for his hapless tenants and squeezed the maximum rent out of everyone, himself occupying a narrow ledge abutting the street, where he had a shop selling, among other things, sweets, pencils and ribbons to children swarming from the municipal school across the street. When he locked up for the night, he slept across the doorway so that no intruder should pass without first stumbling on him; he also piled up cunningly four empty kerosene tins inside the dark shop so that at the slightest contact they should topple down with a clatter: for him, a satisfactory burglar alarm.

Once at midnight, a cat stalking a mouse amidst the grain bags in the shop noticed a brass jug in its way and thrust its head in out of curiosity. The mouth of the jug was not narrow enough to choke the cat or wide enough to allow it to withdraw its head.
