NCERT Solutions Class 12 English Chapter 6 Kaleidoscope Non Fiction On Science Fiction

Stop And Think

Question 1. What is the parallel drawn between myths and legends of the past and science fiction?
Answer: Isaac Asimov draws a clear parallel between ancient mythology and modern science fiction by pointing out that both genres are born from the same fundamental human desire for wonder and extraordinary capabilities. Ancient myths and legends are filled with tales of gods, demigods, and heroes possessing supernatural powers, using magical artifacts such as crystal balls to view distant events, or riding winged horses and flying carpets to navigate the skies. Similarly, science fiction utilizes imaginative hypotheses, speculative science, and technological marvels to achieve these very same results. While the ancient stories explained these wonders through magic and divine intervention, science fiction explains them through advanced technology and scientific principles. Ultimately, both genres share the same goal: exploring the boundaries of human possibility and depicting life beyond our current understanding.
In simple words: Myths and science fiction both fulfill our desire for wonder and extraordinary powers. While ancient legends used magic (like flying carpets and crystal balls) to explain these wonders, science fiction uses speculative technology to achieve the exact same goals.

Exam Tip: Explain that the primary parallel between the two lies in their shared "emotional objective" - satisfying our biological longing for wonder - though they differ in their explanations (magic vs. science).

Question 2. What gives science fiction its validity?
Answer: According to Asimov, what validates science fiction and distinguishes it from ancient mythology is its alignment with the realistic, objective laws of the physical universe. Ancient myths and legends operated in a chaotic cosmos governed by unpredictable gods, demons, and magical enchantments that could only be influenced by spells or prayers. In contrast, science fiction operates within a structured universe governed by impersonal, rational, and discoverable laws of nature. Because modern science has proven that the universe does indeed follow these unyielding physical laws - rather than the whims of mythical deities - only science fiction is valid in the modern era, as its speculations are grounded in our best understanding of reality.
In simple words: Science fiction is valid because it is based on a universe ruled by logical, unchanging laws of nature. Unlike myths, which rely on magic and unpredictable gods, science fiction assumes that everything in the cosmos can eventually be understood and explained through science.

Exam Tip: Emphasize that the "validity of science fiction" stems from its foundation in a "natural-law-bound universe" rather than a "supernatural-whim-bound universe."

Question 3. Which literary works does the author have in mind when he refers to ‘Open Sesame’ or the concept of winged horses or flying carpets?
Answer: When referencing "Open Sesame," winged horses, or flying carpets, the author has classical works of ancient folklore, mythology, and fantasy in mind, most notably The Arabian Nights (or One Thousand and One Nights). "Open Sesame" is the magical phrase used to open the thieves' cave in the story of "Ali Baba and the Forty Thieves." Similarly, winged horses (such as Pegasus from Greek mythology) and flying carpets are iconic symbols of early human fantasies about flight and transportation. Asimov uses these examples to show how early, pre-scientific literature utilized magic to achieve what modern technology has now made possible through remote-control devices and airplanes.
In simple words: The author is referring to classic folk tales and myths, such as "Ali Baba and the Forty Thieves" from The Arabian Nights, which used magic spells and flying carpets to imagine things that modern technology has now actually created.

Exam Tip: Identify The Arabian Nights (or One Thousand and One Nights) and Greek mythology as the specific literary sources behind these magical concepts.

Understanding The Text

Question 1. What makes for the distinction between the various genres of fiction—‘a sports story’, ‘a Western story’, ‘a jungle story’ and science fiction?
Answer: Asimov establishes that while most genres of fiction are defined by their specific characters or plot contents, science fiction is uniquely defined by its background. A sports story, for instance, must center on athletic competition and games. A Western story must depict the nomadic, rugged lifestyle of cowboys in the nineteenth-century American West. A jungle story must involve the dangers and survival challenges of a tropical wilderness. In all these cases, the plot is restricted to a narrow, specific subject. In contrast, science fiction is not restricted to any single topic; its characters can play sports, solve mysteries, or fall in love. What makes it distinct is its background - a speculative, scientifically plausible setting that differs from our own, allowing it to act as an expansive, limitless literary universe.
In simple words: Most genres are defined by their plot content (like sports or cowboys), but science fiction is defined solely by its background. It can be about any subject, as long as it takes place in a scientifically plausible, speculative setting.

Exam Tip: Use Asimov's core argument that "content defines other genres, but background defines science fiction" to write a precise, structured comparison.

Question 2. How does Asimov establish that John Campbell was wrong in his opinion that it is not possible for a science fiction mystery to be fair to a reader in the same way as a classical mystery is?
Answer: John W. Campbell, a highly influential editor, argued that a science fiction mystery could never be fair to readers because the writer has unlimited opportunities to invent futuristic gadgets or scientific rules to solve the crime at the last second, cheating the reader. Asimov refutes this view by asserting that a science fiction mystery can easily be fair if the author strictly follows the rules of the game [1]. Just as a classical mystery writer must present all clues honestly, a science fiction writer must clearly establish the boundaries, futuristic technology, and scientific laws of their imaginary world early in the story [1]. If these rules are laid out transparently to the reader beforehand, the mystery can be solved logically and fairly without any sudden, unfair inventions.
In simple words: Campbell thought science fiction mysteries were unfair because writers could invent any futuristic gadget to solve the crime at the last second. Asimov argues that if the writer clearly explains the rules and technology of their imaginary world early in the story, the mystery remains perfectly fair and logical.

Exam Tip: Discuss the "rules of the game" in mystery writing, showing how introducing the speculative science early in the story ensures fairness for the reader.

Question 3. What are the pitfalls that the writer of science fiction mystery must guard against?
Answer: Writing a science fiction mystery carries unique challenges and pitfalls that the author must carefully guard against [1]. The primary danger is the temptation to cheat the reader by using sudden, unexplained futuristic technology or changing the rules of the fictional universe to resolve the plot [1]. Another major pitfall is failing to find a balance between the science and the mystery [1]; the author must understand both real science and how to logically extrapolate it into the future [1]. If the science is too unrealistic, it loses its credibility, but if it is too detailed, it can slow down the pace of the mystery. Thus, the writer must ensure that the speculative science is introduced early and integrated seamlessly into the plot.
In simple words: A writer must avoid two main traps: changing the rules of their imaginary world suddenly to solve the crime, and making the science so complicated or unrealistic that it ruins the logic of the mystery.

Exam Tip: List "changing rules mid-story" and "failing to explain the technology early" as the two primary pitfalls to avoid in this genre.

Talking About The Text

Question 1. Imagination and fantasy help human beings to speculate upon the possible explanations for the complexity and unpredictability of the phenomena in the universe.
Answer: Science does not offer an absolute, final truth, nor does it assume that every mystery in the universe can be easily solved. Human intellect has limits, and many natural phenomena remain highly complex and unpredictable. This is where creative imagination and fantasy play a crucial role. Before a scientific theory can be proven in a laboratory, it must first be imagined. Speculative thoughts and creative fantasies allow us to visualize potential explanations, ask bold questions, and explore alternative realities. In this sense, science and imagination are closely linked, as major scientific breakthroughs are often born from a creative mind trying to make sense of the unknown.
In simple words: Science cannot explain everything easily, so we need imagination and fantasy to ask bold questions and visualize possible answers. Almost every great scientific discovery began as a creative idea in someone's mind.

Exam Tip: Focus on how imagination acts as a precursor to scientific inquiry, allowing researchers to theorize and speculate before experimental proof is possible.

Question 2. The difference that science and technology have made to everyday life today was visualised in science fiction fifty years ago.
Answer: This statement highlights how science fiction acts as a bridge between the present and the future. Many of the everyday technological devices we take for granted today - such as mobile communication, automated doors, computers, and space travel - were envisioned by science fiction writers fifty years ago. At that time, these concepts were viewed as wild, impossible fantasies. However, through continuous research and engineering, these speculative ideas took physical shape, transforming our daily lives. This shows that science fiction is not just entertainment; it serves as a highly perceptive map of technological progress, predicting changes before they occur.
In simple words: Many of the gadgets we use every day, like video calls and automatic doors, were imagined in science fiction movies and books decades ago. What once seemed like impossible magic has now become a normal part of our lives.

Exam Tip: Provide specific examples of past science fiction predictions (like automated doors or communication devices) that have become normal everyday realities today.

Appreciation

Question 1. Discuss the author’s attitude towards the pre-scientific imagination and the tone he adopts while talking about it.
Answer: Asimov views pre-scientific imagination - which includes ancient mythology, legends, and magical tales - with a blend of intellectual respect and scientific detachment. He recognizes that these ancient stories filled the same biological need for wonder and curiosity that science fiction satisfies today. However, his tone remains highly analytical, objective, and slightly critical. He describes these pre-scientific ideas as "absurd" and superstitious from a logical standpoint, pointing out that they operated in a chaotic universe ruled by gods and demons rather than structured laws. While he enjoys their creative beauty, he firmly asserts that only science-based speculation is valid in our modern, rational era.
In simple words: The author respects ancient myths for their creativity and wonder, but his tone is analytical and critical. He views magic and superstition as unscientific, pointing out that modern science fiction is superior because it is based on logical natural laws.

Exam Tip: Identify his dual attitude - admiring the "emotional creativity" of myths while rejecting their "magical explanations" with an analytical, slightly critical tone.

Question 2. Observe how the paragraph, as a form, has been used in the essay. Some paragraphs consist of just one sentence. What purpose do you think the author had in putting them in this manner?
Answer: In his essay, Asimov occasionally uses single-sentence paragraphs to achieve a powerful rhetorical effect. Two prime examples of this are: 1. "The goals of these ancient stories are the same as those of modern science fiction - the depiction of life as we don’t know it." 2. "Science fiction is a literary universe of no mean size because science fiction is what it is, not through its content but through its background."
The author's primary purpose in isolating these statements is to give them maximum emphasis and clarity. By presenting these core arguments as standalone paragraphs, he ensures they stand out from the surrounding text, drawing the reader's attention to the most crucial, foundational ideas of his essay.
In simple words: The author sometimes writes paragraphs that are only one sentence long. He does this to emphasize his most important arguments, making sure they stand out clearly and grab the reader's attention.

Exam Tip: Explain that single-sentence paragraphs serve as "rhetorical markers" that summarize complex arguments into clear, unforgettable statements.

Question 3. Mark the linkers used by the author to connect the point he makes in one paragraph with that in the next. For example, let me explain the difference that makes in the last line of Para 1 of Section II. These are called discourse markers or discourse signallers.
Answer: Asimov makes excellent use of discourse markers (or linkers) to guide the reader smoothly from one paragraph's argument to the next, maintaining a highly logical flow. Two prominent examples from the text are: 1. At the end of his discussion on ancient stories, he connects it to the emotional core of science fiction by writing: "The emotional needs that are fulfilled are the same, the satisfaction of the longing for wonder." This transitions the argument from historical comparison to human psychology. 2. To move from the definition of science fiction to its distinct characteristics, he uses the linker: "Let me explain the difference that makes." This prepares the reader for the detailed, comparative analysis of genres that follows.
In simple words: The author uses transitional words and phrases, called discourse markers, to link his paragraphs together. This keeps his arguments flowing smoothly and logically, helping the reader follow his transitions easily.

Exam Tip: Explain that these linkers, such as "Let me explain the difference," act as signposts that maintain the "unity and coherence" of his argumentative writing.

Language Work

Question 1. (i) Look up a literary dictionary or encyclopaedia or the internet to understand the references to the following mythical creatures: Centaur, Satyr, Sphinx, Harpy, Gryphon, Gorgon, Pegasus. (ii) Find out about the story of Achilles and Hector.
Answer: (i) Definitions of the Mythical Creatures:

• Centaur: A legendary creature from Greek mythology with the upper body of a human and the lower body of a horse, representing a wild, untamed nature.
• Satyr: A woodland spirit in Greek myths, depicted as half-man and half-goat, known for its mischievous and joyful behavior.
• Sphinx: A mythical creature with the body of a lion and the head of a human (or a bird), famous in Greek and Egyptian legends for posing difficult riddles to travelers.
• Harpy: A creature with the head and torso of a woman and the wings and claws of a bird of prey, representing storm winds in classical mythology.
• Gryphon (Griffin): A legendary beast with the body of a lion and the head, talons, and wings of an eagle, symbolizing strength and vigilance.
• Gorgon: A female monster, such as Medusa, with living snakes for hair whose terrifying gaze turned anyone who looked at her into stone.
• Pegasus: A magnificent, divine winged horse of pure white, born from the blood of Medusa in Greek mythology.

(ii) The Story of Achilles and Hector:
This legendary conflict forms the dramatic peak of Homer's epic poem, the Iliad, set during the Trojan War. Achilles was the greatest warrior of the Greek forces, made nearly invulnerable after his mother dipped him in the river Styx as an infant, holding him by his heel (the famous "Achilles' heel"). Hector was the noble prince and champion of Troy.
During the siege, Hector mistakenly killed Patroclus, Achilles' beloved companion. Fuelled by intense grief and rage, Achilles returned to the battlefield and challenged Hector to single combat outside the gates of Troy. Achilles slew Hector, dragged his body behind his chariot in triumph, but eventually relented and returned the body to Hector's grieving father, King Priam, for a proper burial. Achilles was later killed near the end of the war by Paris who shot a poisoned arrow into his vulnerable heel.
In simple words: This section defines famous creatures from mythology, like the winged horse Pegasus and the snake-haired Gorgon. It also summarizes the famous story of Achilles, the Greek warrior with one weak spot on his heel, who killed the Trojan prince Hector during the Trojan War.

Exam Tip: For the story of Achilles and Hector, focus on the primary conflict (the death of Patroclus leading to their duel) and explain the origin of the term "Achilles' heel."

Task

Question 1. Here are a few sentences with transitive verbs, adapted from the text. Identify the noun phrases that are the verbs’ objects, and underline them. Then turn these sentences into a passive form.
Answer: Linguistic analysis of the sentences, identifying their direct objects and converting them into passive voice:

1. Sentence: He expected a sudden change of rules.
• Object: "a sudden change of rules"
• Passive Voice: A sudden change of rules was expected by him.

2. Sentence: Nothing prevents writers from using actual science.
• Object: "writers"
• Passive Voice: Writers are not prevented by anything from using actual science.

3. Sentence: He revealed that he didn't know the difference between the element and the compound.
• Object: The noun clause "that he didn't know the difference between the element and the compound"
• Passive Voice: It was revealed by him that he didn't know the difference between the element and the compound.

4. Sentence: He demonstrated that he couldn't tell the difference between carbon monoxide and carbon dioxide and reduced the plot to a shambles.
• Object: The noun clause "that he couldn't tell the difference between carbon monoxide and carbon dioxide"
• Passive Voice: It was demonstrated by him that he couldn't tell the difference between carbon monoxide and carbon dioxide, and the plot was reduced to a shambles.

5. Sentence: The writer must carefully explain to the reader all the boundary conditions of the imaginary society.
• Object: "all the boundary conditions of the imaginary society"
• Passive Voice: All the boundary conditions of the imaginary society must be carefully explained to the reader by the writer.
In simple words: This exercise identifies the direct objects in these sentences and rewrites them in the passive voice. For example, "He expected a sudden change" becomes "A sudden change was expected by him."

Exam Tip: When converting complex sentences with noun clauses (sentences 3 and 4) into passive voice, use the dummy pronoun "It" as the subject (e.g., "It was revealed by him that...") to keep the sentence natural and grammatically correct.

Question 2. Some verbs take a that-clause after them. Find the verb asks in the last paragraph of the first part of this text (which begins ‘I don’t even ask that…’) and note how it is followed by that clause. Look for other verbs, in this text as well as in the earlier ones, that are followed by a that-clause (verbs such as believe, know, realise, promise…)
Answer: Analysis of the verb "ask" and other verbs followed by a "that-clause" in the text:

In the final paragraph of the first section, we find the following lines:
"I don't even ask that they be wrenched out of context... I ask only that they be self-consistent..."
In these instances, the verb "ask" is followed by a subordinate noun clause introduced by the conjunction "that."

Other examples of verbs followed by a "that-clause" in this text and previous chapters include:

• believe: "I don't believe that it was made by a nail after all..." (from The Mark on the Wall)
• know: "He revealed that he didn't know that there is a difference..."
• realise: "She soon realised that her actions were being closely watched by her son." (from One Centimetre)
• promise: "She had promised that she would keep the home together." (from Eveline)

In simple words: Certain verbs, like "ask," "believe," or "realize," are often followed by a "that-clause" to complete their meaning, such as: "I ask that..." or "I believe that..."

Exam Tip: In English grammar, "that-clauses" function as noun clauses serving as the direct object of transitive verbs like ask, believe, know, or realize.
