Questions and Solutions

Comprehension Check I - Question 1

How does Tilloo manage to find his way to the 'forbidden passage'?
Solution:

Tilloo cleverly manages to reach the 'forbidden passage' by taking advantage of a moment when his mother is not watching. He also uses his father's security card, which likely grants him access to areas that are usually restricted.

Comprehension Check I - Question 2

What did Tilloo hope to see once he emerged from his underground home?
Solution:

Having lived his entire life underground, Tilloo harbored a deep curiosity about the world above. He hoped that upon reaching the surface, he would be able to see the sun if it was daytime, or the stars if it was nighttime, as these celestial bodies were only things he had heard about.

Comprehension Check I - Question 3

Why did Tilloo's father advise him not to try to reach the surface of the planet?
Solution:

Tilloo's father advised him against going to the surface due to the extremely harsh and dangerous environmental conditions. The air on the planet's surface is described as being too thin for humans to breathe comfortably, and the temperature is low enough to be fatal, potentially freezing a person to death. These factors make survival on the surface nearly impossible for ordinary individuals.

Comprehension Check I - Question 4

What changes had occurred, which forced people to live in underground homes?
Solution:

Significant environmental changes forced the inhabitants to seek refuge underground. The sun, which was once a source of life and sustenance, turned hostile. Even a minor alteration in its behavior drastically upset the planet's natural equilibrium. This hostility led to the extinction of birds, animals, and fish, making the surface uninhabitable and compelling people to construct and live in underground homes for safety and survival.

Comprehension Check II - Question 1

Why was everyone in the Control Room greatly excited?
Solution:

The excitement in the Control Room stemmed from a significant event detected on their systems. The large TV screen displayed that an unidentified object, identified as a spacecraft, was heading towards their location, creating a buzz of anticipation and concern among the personnel.

Comprehension Check II - Question 2

Was the spacecraft manned or unmanned? How do you know it?
Solution:

The spacecraft was unmanned. The text indicates this by stating that while in earlier times, space programs included both manned and unmanned missions, the current phase of their civilization, marked by energy shortages and underground living, did not involve any space programs. Therefore, any spacecraft detected would not have been sent by them and would likely be unmanned.

Comprehension Check II - Question 3

What did Number One and Number Two suggest should be done about the alien spacecraft?
Solution:

Number One and Number Two had differing opinions on how to handle the approaching alien spacecraft. Number One suggested a proactive approach, proposing that they should be prepared to render the spacecraft ineffective at any moment they wished. In contrast, Number Two advocated for a passive strategy, suggesting non-interference and simply observing the spacecraft from a distance. This approach aimed to conceal their civilization's existence and avoid any potential conflict or detection.

Common mistakes
