Answer 1

Answer

(a) Aditya is taking a correct decision. The solar water heater would have been a good choice.

The reasons can be:

(i) No moving parts, little maintenance, work satisfactorily without any focusing device.

(ii) It can be set up in remote and inaccessible hamlets or sparsely inhabited areas. It also has a higher capacity compared to an electric geyser.

(b) Possible changes in the family's thinking:

(i) Harnessing the natural and greatest source of energy, the sun.

(ii) Aditya would have convinced them by explaining the long-term running cost and maintenance of solar versus the initial low cost of an electric heater. Also, hot water will always be available even when there is a power outage.
