Textbook Exercises

Ans. Since, Tilloo and his family lived underground, their house natural light of the Sun. They sustained themselves through the solar energy they were able to generate. Also, being able to roam around freely would be difficult.

Ans. Tilloo’s father recalled how their ancestors lived naturally on the surface of the planet.

A change in Sun, however, led to drastic changes. It is possible that our planet, too, encounters such changes.

People living on other planets could be different because of the distance and physical differences from the Sun.
