I. Answer the following questions briefly.
1. Why did the narrator think Sven had sneaked a bird aboard? What was Sven’s scientific reason?
2. How did Claribel adjust to the new surroundings?
3. What made the narrator mistake the musical whistle for a sound from the intercom?
4. Do you think the presence of the canary would lead the spacers into trouble? If yes, why? If no, why not?
Answer
1. The narrator had some reasons to think so. It was the bird’s unusual behaviour, like her seemingly effortless flight in a space station and lack of concern for the absence of gravity. On the other hand, Sven’s scientific reason for bringing the bird aboard was to observe how a bird would function in a weightless environment. He wanted to experience how a bird could operate and navigate without the effects of gravity.
2. Claribel learnt to operate without using her wings or much efforts. She learnt to simply hang in the air, motionless with her wings folded. This adaptation allowed her to thrive and even gain weight in the unique conditions of her new surroundings.
3. The narrator heard the whistle near his ear. He expects an announcement to follow the whistle, that is typical of intercoms. The melody of the whistle, rather than a human voice, hence leads him to realize it wasn’t the intercom.
4. No, the presence of the canary did not cause trouble. In fact, it helped the crew by warning them about the bad air in the space station.

Let us think and reflect
I. Read the given extracts and answer the questions that follow.
1. Sven was one of our best construction men, and excelled at the tricky and specialised work of collecting assorted girders as they floated around in free fall, making them do the slow-motion, three-dimensional ballet that would get them into their right positions, and fusing the pieces together when they were precisely dovetailed into the intended pattern: it was a skilled and difficult job, for a space suit is not the most convenient of garbs in which to work.
(i) What can be inferred about Sven’s abilities from his job description?
A. He is good at following instructions but lacks creativity.
B. He possesses a strong understanding of working in space.
C. He struggles with the complexities of construction in space.
D. He prefers working on simpler tasks rather than complex jobs.
(ii) How can we conclude that Sven was working in zero gravity?
(iii) Select the option that is correct for both (Assertion) A and (Reason) R.
(A): Sven’s job required him to make girders perform a ‘three-dimensional ballet’ in space.
(R): Working in zero gravity allows objects to float, making precise positioning more challenging.
A. Both (A) and (R) are true, and (R) is the correct explanation of (A).
B. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
C. (A) is true, but (R) is false.
D. (A) is false, but (R) is true.
(iv) Replace the underlined word with a word similar in meaning from
the extract.
During the festival, people wore colourful outfits that represented
their culture.
Answer
(i) B. He possesses a strong understanding of working in space.
(ii) Sven was working in space. His job was to collect assorted girders as they floated around in a free fall. He had to make them do the slow-motion that would get them into their right position and then, fuse the pieces together into the required pattern.
(iii) A. Both (A) and (R) are true, and (R) is the correct explanation of (A).
(iv) Garbs
2. “Jim!” There’s something wrong with the air! That’s why Claribel’s passed out. I’ve just remembered that miners used to carry canaries down to warn them of gas.” “Nonsense!” said Jim. “The alarms would have gone off. We’ve got duplicate circuits, operating independently.” “Er—the second alarm circuit isn’t connected up yet,” his assistant reminded him. That shook Jim; he left without a word, while we stood arguing and passing the oxygen bottle around like a pipe of peace.
(i) Fill in the blank by selecting the correct option from those given in the brackets.
The narrator references canaries and miners in order to ______. (highlight the historical use of canaries as warning systems/explain the reason that caused Claribel to faint suddenly)
(ii) Complete the following sentence with a suitable reason. Jim initially dismisses the warning about the air because ______.
(iii) What does the phrase ‘shook Jim’ mean in the context of the
information in the extract?
Jim was _________.
A. physically pushed by someone
B. startled by unexpected information
C. cold and needed to warm up
D. trying to shake off sleepiness
(iv) What does the crew’s action of passing the oxygen bottle around ‘like a pipe of peace’ suggest about their response to the situation?
Answer
(i) The narrator references canaries and miners in order to highlight the historical use of canaries as warning system.
(ii) Jim initially dismisses the warning about the air because the alarms would have gone off.
(iii) B. startled by unexpected information
(iv) This phrase suggests that the crew is sharing a valuable, life-saving resources equally and perhaps even peacefully during a difficult situation. It also indicates that they are not either selfish or greedy.
II. Answer the following questions.
1. What was the purpose of the alarm? What had caused its failure?
2. How does the crew’s reaction to Claribel change over the course of the story?
3. What does the last part of the story tell us about the significance of unusual ways of problem solving?
4. Justify the appropriateness of the title of the story.
5. ‘Without Claribel, we should soon have been slightly dead.’ What does this line suggest about uncertainty of life in space?
6. Explain how has the writer presented science fiction with a touch of humour.
7. How would Sven reflect on his experience of almost losing Claribel and for saving the lives of the entire crew?
Answer
1. The purpose of the alarm is to detect faults in the air purifier and tell us about the dangerous air conditions, not just low oxygen.
It failed because:
- An eclipse froze part of the air purifier
- Only one alarm circuit was active
- The connected alarm did not go off
2. The crew’s initial reaction to Claribel is one of the curiosity and perhaps even a bit of amusement. They are surprised to see a pet onboard the space station. However, as the story progresses, their feelings towards Claribel evolve, becoming one of deep concern and eventually affection. This shift is largely due to Claribel’s unexpected ability to alert the crew to a dangerous situation, saving their lives.
3. The unusual ways of problem solving revolves around a canary bird named Claribel. She detects air quality issue on a space station. When she passes out due to poor air quality, the crew realizes a malfunction in the air purifier has caused this problem. This shows reliance on a living organism to act as an early warning system for dangerous conditions, a method that might not be immediately obvious or conventional in space.
4. The title of the story, ‘Feathered Friend’ is appropriate. The story directly related to the core theme of friendship and the bond between humans and animals, particularly birds. The title evokes the image of a bird as a companion and a source of joy, that supports the narrator’s focus on the relationship between Sven and Claribel, who is a canary bird.
5. This quote highlights the crucial role of Claribel in alerting the space station crew to a potentially deadly situation, caused by a malfunctioning air purifier. They would have suffered from the poisonous atmosphere, without Claribel’s sensitivity to changes in the air.
6. The narrator’s disbelief in the canary’s ability to thrive in space, and his causal attitude towards breaking rules, creates a comedic contrast with the serious nature of their mission. The over-exaggeration of the space station’s equipment, like the alarm that failed to function, and the crew’s reactions, especially the narrator’s initial sluggishness add a layer of comedic absurdity to the story. Sven is a crew member, and brings Claribel aboard. He is presented as a somewhat eccentric and unpredictable figure, that adds to the overall humourous tone of the story. Moreover, the unexpected way in which Claribel revives and the subsequent events, such as the air purifier freezing, provides moments of light hearted amusement to the story.
7. Sven would look back on the incident with deep relief and gratitude. When Claribel fainted, he must have felt shocked and afraid of losing her, as she was not just a pet but a dear companion. Later, he would realise that her reaction to the bad air had actually saved the entire crew. This would make him value her even more and feel thankful that she was on the space station. The experience would also teach him that even a small bird can play a heroic role and that every living creature has its own importance.

You need to prepare for the inter-class quiz on the topic Chandrayaan-3. Ask your friend for advice on how to prepare.
You may use the prompts given below.
Answer
I need to make a model of the solar system for the Science Exhibition, but I have no idea how I should complete my model. I need your suggestion.
Friend’s suggestions: To make a model of the solar system, first decide if you want to represent planet sizes or distances or both,
and then, choose a scale that fits your space. Now, you should gather materials like craft supplies or materials found around your house. Then, you should think over using paints, markers, or other creative mediums. At last, you should research on the characteristics of each planet, such as size, colour, rings, etc. to accurately represent them on your model. Thus, your model of the solar system for the Science Exhibition would be ready for demonstration.
I need to prepare Inter-class quiz on the topic Chandrayaan-3, but I have no knowledge how to make questions about the important aspects of Chandrayaan-3. I hope you can better suggest me, as you are quiet familiar with this topic. Friend’s suggestions: To prepare a successful inter-class quiz on Chandrayaan-3 is not a difficult task. You should focus on understanding the mission’s goals, key components, and scientific objectives. Moreover, you should include questions about the launch date, landing site, the purpose of the rover and lander, and the instruments they carry. In addition, you shouldn’t forget to touch upon the significance of the lunar south pole and the mission’s broader implications for Indian space exploration. Your quiz kit should contain everything related to this pride mission.

Answer
The Importance of Internet
Aman, Class-7
The last few years have witnessed heavy reliance on the Internet. This has been because of multiple advantages that it has to offer – for instance, reducing work stress and changing the face of communication most importantly. If we take the current scenario, we cannot ignore how important the Internet is in our everyday lives. It is now indeed a challenging task to visualize a world without the internet. One may define the internet as a large library composed of stuff like – records, pictures, websites, and pieces of information. Another sector in which the internet has an undeniably important role to play is the field of communication. Without access to the internet, the ability to share thoughts and ideas across the globe would have also been just a dream.

Let us explore
‘A canary in the coal mine’ is a popular phrase to describe early signs of potential danger.
I. Coal miners in places like Arunachal Pradesh used canary birds to detect the presence of carbon monoxide. Such gases are a potential risk to the life of the miners. These little birds are particularly sensitive to carbon monoxide and can prevent mining accidents.
II. Astronauts living in space stations have to do things differently. Read how they manage the routine tasks in the absence of gravity. You may find out more information about it from the internet.
- Write: Astronauts use a special Space Pen which has a cartridge with ink combined with resin. The ink remains solid until friction with the ball at the point of the pen liquefies it. It works in all positions, in extreme heat and cold, and in atmospheres ranging from pure oxygen to vacuum.
- Exercise: Astronauts use resistance exercise equipment. Weight training is done by applying a load using vacuum cylinders. Running on the treadmill is made possible with the bodies held down using rubber straps.
- Eat: Astronauts eat preserved foods which is dried, canned, vacuum-packed, and frozen. These can be prepared by adding cold or hot water, and some can be heated in an oven. They also eat ready-to-eat items, such as nuts, breads, and fruits.
- Sleep: Astronauts can sleep on a floor, wall, or ceiling as there’s no distinction between up and down but they may gradually float away while sleeping. Therefore, they need to restrain their bodies in small sleeping compartments or sleeping bags.
III. Did you know that animals can save humans from natural calamities? Animals can sense natural calamities. Read the following examples and decide if this is true.
- In 2004, before a tsunami could hit the coastline of Indonesia, some animals made efforts to flee—elephants ran for higher ground, flamingos abandoned low-lying nesting areas, and dogs refused to go outdoors.
- Minutes before the Naples quake of 1805, oxen, sheep, dogs, and geese started making alarm calls in unison.
- Migratory birds crossing the Pacific are able to dodge storms and other hazards.
- In the Gulf of Mexico, sharks sense the drop in barometric pressure that precedes hurricanes and tend to swim to deeper waters as a result. Dolphins have also been observed swimming away from storm-prone areas.
Scientists have studied this behaviour and found that when severe stresses arise in deep rock before the earthquake, ultra-low frequency electromagnetic waves are generated that animals can sense.
IV. Salim Ali, the ‘Birdman of India’, was an Indian ornithologist (a person who studies birds). He was the first Indian to conduct systematic bird surveys across India and wrote several books on birds. He was awarded the Padma Bhushan in 1958 and the Padma Vibhushan in 1976.
V. We need to conserve our ‘feathered’ friends. Work in groups of four.
Look at the pictures and make a bird feeder with cardboard, chart paper, etc.
