Directions: Read the passage carefully and answer the questions that follow.In many Indian cities, water arrives with the clockwork irregularity of tanker trucks. Households store buckets because municipal supply is intermittent, and pressure drops when demand peaks. Administrators debate whether to build costly desalination plants, fix leaky pipes, or price water so that heavy users pay more. Each choice carries trade-offs: desalination is energy-intensive, repairs take time in crowded streets, and higher tariffs risk excluding the poor. Meanwhile, small behavioral nudges—low-flow fixtures, metered billing, and public dashboards—have shown modest but steady gains. The challenge is not merely technical; it is political, requiring trust that savings today will translate into reliable access tomorrow.Q₁. Which of the following best states the central idea of the passage?
