Some special kind of clothing was necessary to survive in the planet which had very less air and freezing temperatures.

Exercises

Discuss the following topics in groups.
1. If you had to live in a home like Tilloo’s, what parts of life would you find most difficult? What compensations might there be?
Ans: 
The part of life I found most difficult is the freedom and open space. It will be like living in a cell far away from open space. There was no sightseeing, social life and interactions with the nature. I would want peace safety, freedom and a fearless place as compensations  to live in.  As all of us would be living in such underground buildings,  people must collaborate with each other nicely.

2. What, if anything, might drive mankind to make their homes underground?
Ans: 
Global warming,depletion of air and water, climatic changes, lack of natural resources to fulfil man`s basic needs may destroy the life on the surface of the Earth and drive mankind to make their homes underground.

3. Do you think there is life on other planets? Can you guess what kind of people there may be on them? In what ways are they likely to be different from us?
Ans: 
 Yes life on other planets is possible. Traces of water have been found on the satellite of Saturn and evidences of life on Mars has been found in Mars in the past and present. Large quantites of underground ice have been seen on Mars which proves it was inhabited in the earlier times.
