These questions have been taken from previous years class 10 Board exams and the year is mentioned in the bracket along with the question.

How does Think-Tank explain the books to his probe crew?

Answer. Think-Tank explained to his team that the books were sandwiches. He even told his men to eat them. He then referred to them as communication devices, and later stated that they were intended for surveillance.

Q2. Why do the space probe crew take vitamins?

Answer. Think-Tank wanted the probe team to discover what was written in the books. As a result, the probe crew takes vitamins to boost their intelligence. After taking those vitamins, they were able to read the books.

Q3. Think-Tank thinks that Earthlings are after him. What is the reason? (CBSE 2015)

Answer. The Think-Tank crew read the rhyme about Humpty-fall Dumpty’s and showed the picture to Think-Tank. Think-Tank’s head looked like Humpty- Dumpty’s. Think-Tank concludes that Earthlings intended to invade Mars and capture him.

Q4. Mention any two striking qualities of Noodle.

Answer. The apprentice of Think-Tank, Noodle, emerges as an intriguing character in the story. He is courteous and intelligent. He humbly corrects his ruler’s errors by making indirect suggestions. He is also very wise and well-informed.

Q5. How did one old book of nursery rhymes save the Earth from a Martian invasion? (CBSE 2011)

Answer. The Martians completely misunderstand this book. The Martians believed that humans were planning an invasion of Mars. As a result, they canceled their invasion of Earth and returned. Think-Tank completely misinterprets the book. Phrases like shell, “silver,’ and ‘garden’ led him to believe that earthlings grew silver and weapons. He begins to believe that humans are technologically advanced.

Q6. The 20th century was referred to as the ‘Era of the Book’. Comment briefly.(CBSE QB,2021)

Answer. The twentieth century was dubbed the “Era of the Book” because there were books on everything from anteaters to Zulus at the time. Books taught them how, when, where, and why to do things. They drew, taught, punctuated, and even decorated.

Q7. Describe briefly how the Martians reach upon the correct application of the book. 

Answer. Martians arrived at the library during the invasion of Earth. They’d never seen books before. They had no idea where they were or what the items in the various racks were. They initially mistook them for sandwiches and attempted to eat them. They then misinterpreted sandwiches as some sort of communication device. Later, they recognised them as eye communication rather than ear communication, and realized that they needed to take vitamins to understand all of these codes.

Q8. Where did Captain Omega reach with her team?

Answer. Captain Omega and her crew arrived on Earth. They were in the Centerville Public Library, surrounded by thousands of books. They mistook themselves for being in a storage facility.

Q9. Noodle avoids offending Think-Tank but at the same time he corrects his mistakes. How does he manage to do that?

Answer. Noodle takes great care not to offend Think-Tank. He never disagrees with his opinion, but he never misses an opportunity to offer his suggestions, even if he does so hesitantly. He is always impressed by ThinkTank’s intelligence. He never puts himself into the conflicting ideas from his boss.

Q10. What saved the Earth? How?

Answer. The earth was saved from a Martian invasion by a dusty old book of nursery rhymes. The Martian could not decipher the meaning of nursery rhymes. Their misunderstanding made the situation amusing. They began to believe that the Earthlings possessed advanced technology and intended to invade Mars. They canceled their mission and even left Mars alone in order to escape to a distant planet.


Class 10 The Book That Saved The Earth Long Answer Questions Lesson 10

‘Pride has a fall’. Justify this statement giving relevant points from how Think-Tank reacted to the readings from Mother Goose.

Answer. Martians invaded Earth and made their way into a library. Their boss was Think-Tank. He was very proud of his wisdom, owing to his large balloon-like head. He considered himself to be the wisest person on Mars. Nobody could disobey him, or even dare to speak against him. He claimed to have a quick mind. He had no regard for anyone and dismissed other people’s opinions as trivial. He was also inconsistent.

He misinterpreted the rhymes in a complete verbal manner. Mar, the rhyme mistress, made him think about the discovery of the Earth. He was alarmed by the poem diddle-diddle, and he was so terrified by the poem Humpty-Dumpty that he decided to flee his kingdom and travel to Alpha Centauri. Thus his great wisdom was defeated and had a great fall.

Q2. Historians speak highly about books. How can books help in averting a catastrophic situation? Explain with reference to ‘The Book That Saved The Earth’.

Answer. The setting for The Historian is the twenty-fifth century. He is attempting to escape the twentieth century. He refers to it as the Era of the Book and speaks highly of books. Books, he believes, control all aspects of life. Books educate children. Books teach people how, when, where, and why to do things. They illustrate, educate, punctuate, and even decorate people’s lives. According to the Historian, only the books saved the Earth from Martian invasion, for the Martians had misunderstood the meaning of the poems and got frightened of them. So they rushed away from Earth, even evacuating Mars, and headed for Alpha Centauri.

Even in our day to day life, we get all our solutions from books whether-it is health related or anything else. So we can say that books help us in preventing a catastrophe.

Q3. Noodle hails Think-Tank as the most powerful and intelligent creature in the whole universe. Do you agree? Write your opinion of Think-Tank citing instances from the given text.

Answer. Noodle is Think-Tank’s trainee. He prostrated himself before him and praised his ruler as the most powerful and intelligent creature in the universe. Think-Tank, on the other hand, is not particularly intelligent. He completely misinterprets the nursery rhymes. For him, the words silver, “shells,’ and ‘garden’ indicate that earthlings grow metals in farms. He considers books to be sandwiches and desires that the crew consume them. When he hears the nursery rhyme ‘Humpty-Dumpty had a great fall,’ he becomes terrified and plans his escape from Mars. As a result, Think-Tank is nothing more than a showy and pompous fool.

Q4. Compare and contrast the characters of Noodle and Think-Tank. (CBSE 2012)

Answer. Noodle and Think-Tank have opposing personalities. Think-Tank likes to be called the ‘Great and the Mighty’. He gives orders and commands. He is the ruler of Mars, but he is illiterate.

He compares books to sandwiches. He is incorrect in every way. He demands that the crew follow his orders. He enjoys claiming other people’s ideas as his own. He is a coward who brags about his power.

Noodle, his apprentice, is extremely intelligent and wise. He gently corrects the ruler’s (Think- Tank’s) errors. He never claims ownership of his ideas. But he does so very gently to the ruler. Think-Tank designs them on his own.

Q5. How do the three nursery rhymes frighten Think-Tank in the play, ‘The Book That Saved the Earth’?

Answer. Contrary to popular belief, the rhyme ‘Mistress Mary’ leads Think-Tank to believe that Earthlings have discovered a way to combine agriculture and mining. He believes they can grow explosives. The rhyme ‘Hey diddle diddle’ leads him to believe that Earthlings have advanced to a high level of civilization: even their animals have musical culture and are familiar with space techniques.

He fears that the Earthlings are about to launch an interplanetary attack involving millions of cows. The rhyme is read by Oop. ‘Humpty Dumpty,’ he says, holding up a picture of Humpty Dumpty. Think-Tank concludes that it is his image, and that the Earthlings intend to invade Mars.

Q6. Attempt a character-sketch of Noodle highlighting the values projected by him.

Answer. Noodle is a member of the invasion team that arrived to invade Earth. Apprentice Noodle is his name. He serves as the liaison between Think-Tank and the invasion team. In every way, he is a carbon copy of Think-Tank. He is a very intelligent creature. He understands that Think-Tank, as commander-in-chief, must be obeyed. As a result, he continues to praise Think-Tank while also making sarcastic remarks. Only Noodles thinks practically and differently about the books that were thought to be sandwiches to eat. But Think-Tank claimed the concept as his own. But Noodle isn’t depressed at all. He is a devoted Think-Tank supporter.

Q7. Comment on the appropriateness of the title of the play ‘The Book that Saved the Earth’.

Answer. A good title should reflect a character’s theme, idea, or traits. It gives us a glimpse into the plot. It should be centered on one of the above. The story or the play should be woven around any one of them. In the play ‘The Book That Saved The Earth,’ a book of ‘Mother Goose’ nursery rhymes is responsible for stopping the Martian invasion on Earth. Mars’ ruler, Think-Tank, plans to invade Earth before lunch and sends Probe One to learn more about the Earthlings. They walk into a library but have no idea what the books are. They take vitamins, boost their intelligence, and then read ‘Mother Goose’ rhymes.

Think-Tank interprets the rhymes incorrectly, mistaking them for threats to him and Mars. Scared, he summons Probe One, abandons the plan to invade, and flees with his subjects to Alpha Centauri, a hundred million miles from Mars. As a result, the book ‘Mother Goose’ was responsible for preventing the Martian invasion of Earth. The title “The Book That Saved the Earth” is an apt title because it reflects the theme of the play.

Q8. What is Think-Tank’s opinion about the Earth?

Answer. Think-Tank referred to Earth as a ridiculous little planet and expressed his desire to place it under his generous rule. To him, the planet Earth was insignificant. He thought the Martians were the most attractive race. He referred to the people of Earth as Earthlings and made fun of their small heads.

Before lunch, he expressed his desire to invade the “primitive ball of mud” known as Earth. However, after misinterpreting the nursery rhyme book, he began to believe that the Earthlings had developed a more advanced civilization and were even planning an invasion of Mars.

Q9. If you were in Noodle’s place, how would you have handled Think-Tank’s mistakes?

Answer. Captain Think-Tank was a proud and powerful man. He enjoys being honored by other captains and dislikes having his mistakes corrected. Noodle avoids correcting his errors as well, but he does his work very nicely and gracefully. If I had been in Noodle’s shoes, I would have handled the situation the same way he did.

It is said that humility has the power to move mountains. I would correct Captain Think’s mistakes  in the most humble, modest, and respectful manner so that he does not become annoyed or irritated as he does in the beginning when Noodle misses some part of his salutation but pacifies him with his modest manner.

Q10. Half-Baked knowledge is always dangerous. Rushing to conclusions without going deep into the details of things always leads to uninvited chaos and disasters. Explain the above-mentioned statements in the light of Think-Tank’s interpretations of the rhymes of the book ‘Mother Goose’.

Answer. Nothing is more dangerous than half-baked knowledge. The truth is more than meets the eye. And so is understanding. We must take a broad view of the situation. We must delve deeply into the details before making broad generalizations. Statements that are too broad are never good statements. Misinterpretation of things can sometimes lead to unavoidable disasters. Think-Tank represents how a half-baked mind could have resulted in an invasion of another planet.

Think-Tank excelled in misinterpreting and misrepresenting information. They couldn’t tell what books were when they saw them. He jumped from one conclusion to the next. He mistook them for sandwiches. He misapplied the phrase “had a great fall” to his own demise. He screamed and immediately ordered the evacuation of Mars. He had the impression that Mars was about to be invaded. He made the decision to flee in a space shuttle as soon as possible. He stated that they could travel 100 million miles away from Mars.
