Short Answer Questions 

(Instruction: Answer the following questions in 2–3 lines.)

Q1. Why was Claribel considered an ideal pet for the space station?
Ans: Claribel was thought to be the perfect pet for the space station because she was very light and did not require much food, which was important in space where resources were limited. She could also adapt quickly to the unusual conditions of zero gravity, unlike many animals. Her small size and easy care made her less of a burden for the astronauts.

Q2. Why did the crew have trouble hiding Claribel from VIP visitors?
Ans: The astronauts had difficulty hiding Claribel whenever important guests visited the space station. This was because Claribel often made sudden loud whistles and peeps that could easily give her presence away. Since pets were not officially allowed, the crew worried that these noises might alert the visitors and expose their secret.

Q3. How did Claribel save the crew from disaster?
Ans: Claribel saved the astronauts’ lives in an unexpected way. One day, she suddenly fainted, which was unusual and caught the crew’s attention. This fainting made them realize that the oxygen level inside the station was dropping. On checking, they discovered that the oxygen purifier had failed, and thanks to Claribel’s warning, they were able to fix it in time.

Q4. Why was the alarm system unreliable?
Ans: The alarm system that was supposed to detect oxygen problems was not dependable. Only one circuit had been connected to the system, and unfortunately, it failed to work when the oxygen purifier froze. Because of this, the astronauts could not rely on the machine to alert them to the danger.

Q5. What lesson does the story suggest about technology and nature?
Ans: The story suggests that technology, while advanced, is not always completely reliable. Machines can fail at critical moments, as seen with the alarm system. However, sometimes simple creatures like Claribel, with natural instincts and reactions, can provide warnings that even advanced systems miss. It reminds us that nature too has its own intelligence and importance.

Ans: Rain was extremely important for Velu and his village because their lives depended entirely on farming. The soil was dry and cracked without rainfall, and crops could not grow in such harsh conditions. Since there were no irrigation facilities, rain was the only source of water for cultivation. Without it, farmers faced hunger, poverty, and despair, as their survival was tied to the yield of their fields.

Q2. Why did Velu feel punished despite working honestly?
Ans: Velu was a hardworking farmer who toiled day and night in his fields with complete honesty and dedication. However, despite his efforts, nature did not reward him with rainfall, leaving his land barren. This made him feel as though he was being punished unfairly, even though he had done nothing wrong. His disappointment came from the helplessness of seeing all his hard work go to waste simply because the rain did not come.

Q3. How did the old woman explain the absence of rain?
Ans: The old woman comforted Velu by saying that even the earth, like humans, needed some time to rest. She explained that the absence of rain was nature’s way of giving the land time to regain its strength and rejuvenate. According to her, just as farmers worked hard and then rested, the earth too required pauses to prepare itself for the next cycle of cultivation. Her words gave a new perspective to Velu’s despair.

Q4. What difference did the conversation with the old woman make to Velu?
Ans: The old woman’s words had a calming and transformative effect on Velu. Until then, he had been upset and hopeless, feeling punished by the lack of rain. But after listening to her wisdom, he began to realize that nature has its own rhythm and that the land also deserves time to rest. This conversation helped Velu accept the situation with more patience and hope, instead of anger and frustration.

Q5. How did Velu’s mood change at the end of the story?
Ans: By the end of the story, Velu’s mood shifted completely. From being sad, tired, and hopeless at the beginning, he turned cheerful and full of excitement when he finally saw the clouds gathering in the sky. The first drops of rain filled him with joy and relief, as it not only promised the revival of his fields but also restored his faith and optimism for the future.
