1. Tilloo and his parents live beneath the surface of a planet under artificial
conditions.
2. Tilloo made his way to the forbidden passage.
3. Tilloo accompanies his father to the Control Room.
4. The big TV screen in the Control Room shows an alien spacecraft.
5. The question whether there is life on other planets exercises
everybody’s mind.
State True or False:
1. Tilloo had heard and read about the sun and the stars but he had never seen
them. (True)
2. Tilloo was not interested to know about the secret passage his father used
to go. (False)
3. The President of the Central Committee was about to make an important
statement. (True)
4. The mechanical hand could not be activated again. (False)
5. The mechanical hand could find no signs of life on that planet. (True)
Answer these questions:
1. How does Tilloo manage to find his way to the ‘forbidden
passage’?
Ans- One day when Tilloo’s father was enjoying a siesta
at home, he managed to get hold of his security card. Then, he made his way to
the ‘forbidden passage’ evading his watchful mother’s eye.
2. What did Tilloo hope to see once he emerged from his underground
home?
Ans- Tilloo hoped to see the sun (if it was daytime) or the
stars (if it was night) once he emerged from his underground home.
3. Why did Tilloo’s father advise him not to try to reach
the surface of the planet?
Ans-
Tilloo's father advised him not to venture to the surface of the planet because
the air was so thin that an ordinary person could not breathe and the
temperature was so low that one would freeze to death.
4. What changes had occurred, which forced people to live in
underground homes?
Ans-
The sun that provided them with sustenance became hostile, upsetting the
balance of nature on this planet. Birds went extinct, animals followed, fish couldn't
cope. People were forced to live in underground homes.
5.
Why was
everyone in the Control Room greatly excited?
Ans-
The Control Room was greatly excited because the big TV screen was showing a
dot in an otherwise clear background. Actually, two spacecrafts were
approaching the planet.
6.
Was the
spacecraft manned or unmanned? How do you know it?
Ans-
The spacecraft was unmanned because people in the control room saw a
mechanical hand emerging from the spacecraft.
7. What did Number One and Number Two suggest should be done
about the alien spacecraft?
Ans- Number One’s suggestion
was to let the spacecrafts land on the planet as they could render them
ineffective at any time.
Number Two
recommended non-interference and passive observation. If they interfere with
those spaceships or render them ineffective, they might reveal their existence.
8. What do you think the mechanical hand was trying to do?
Ans- The mechanical hand probably tried to collect a sample of soil from the surface of the planet.
9. Tilloo pressed the red button and “the damage was done”. What was the damage?
Ans- As Tilloo pressed the red button on the panel, the
mechanical hand from the alien spacecraft stopped working.
10. Where had the spacecraft come from?
Ans- The spacecraft had come from the neighbouring
planet.
11. On which planet do Tilloo and his parents live?
Ans- Tilloo and his parents lived on the planet
Mars.
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?
Response- If I had to
live in a home like Tilloo’s, I would find going out on weekends most difficult.
To compensate this, there might be underground amusement parts and play areas
there.
2. What, if anything, might drive mankind to make their homes underground?
Response- If anything
drives mankind to make their homes underground, we will miss chirping of birds,
walking in the forest-way, breathing fresh air, climbing on trees, tracking on
mountains, pitter-patter of rains and many other things.
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?
Response- In our solar-system,
only the planet Earth has the conditions favourable for life. But there can be
some life-forms on far away plants beyond our solar system. There may be people
like us or very different from us. They might be different from in not only in
their physical system but also in terms of culture and values.
