Q1 Sociological Contrast • Urban Living
What differences did Nandita find between getting water in her village and getting water in Mumbai's chawl? Why was she afraid of taking the high-rise lift initially?
[3 Marks]
✅ Step-by-Step Solution & Working
1. Difference in Water Collection:
• In the Village: There were no water taps, but Nandita walked 20 minutes to a clean village pond or well. There were never any fights or shouting; water was available throughout the day.
• In Mumbai's Chawl: Water arrived at a single public tap only from 4:00 am to 5:00 am. If you didn't reach on time, there was no water for the whole day. People pushed, fought, and screamed in long bucket queues.

2. Fear of the Lift:
Nandita had never seen a multi-story iron cage moving vertically. When she entered the lift with multiple people and the doors slid shut, the sudden upward acceleration made her stomach churn, causing her to hold onto the metal railing in panic.

Water Wastage Awareness in Cities

While cleaning utensils at the high-rise flat, Nandita noticed the housemaid left the kitchen tap running continuously while gossiping.

Analytical Task: Why did this upset Nandita, and what should every citizen do to prevent water wastage?
Evaluation & Model Answer:
Nandita was heartbroken because she knew how desperately her Mama and aunties fought at 4:00 am for just a single bucket of water, while here precious drinking water was poured down the drain carelessly. Citizens must turn off taps while brushing or soaping dishes, repair leaking valves, and cherish every drop.
