Learn the Book that Saved the Earth Question and Answer

The twentieth century was famously called the "Era of the Book." During this time, books were used for everything, from learning about Zulus to anteaters. They were a big part of life, teaching people how, when, and where to do things. Books helped to teach, explain, and even decorate the human world.

Martians Try to Attack Earth

The story starts with Martians planning to attack Earth in the twenty-first century. A leader named Great and Mighty Think-Tank leads the group from Mars Space Control. He thinks humans are not smart, but his own pride leads to a big mistake.

Leader: Great and Mighty Think-Tank.
Helper: Noodle (the smart student).
Team on Earth: Captain Omega, Lieutenant Iota, and Sergeant Oop.

How a Nursery Rhyme Saved Us

The most important part of the play is when the Martians find a book called Mother Goose. Think-Tank does not know much about Earth. He misunderstands simple nursery rhymes and thinks they are scary military secrets or warnings.

First Guess: Think-Tank thinks books are "sandwiches" meant for eating.
Second Guess: He then thinks they are "ear-communication" tools.
Final Guess: He decides they are "eye-communication" tools for reading.

NCERT Solutions for Class 10 English Footprints without Feet Chapter 10

Question 1. Why was the twentieth century called the ‘Era of the Book’?

The twentieth century was known as the "Era of the Book" due to the abundance of publications covering a wide range of topics, from Zulus to Anteaters. People learned how, when, where, and why to do things from books. Books have graphics, punctuation, and even decoration.

Question 2 . Who tried to invade the earth in the twenty-first century?

Martians tried to invade the earth in the twenty-first century.

Read and Find Out (Page No. 65)

Question 1 . What guesses are made by Think–Tank about the books found on earth?

At first, the Think Tank assumes that the books are sandwiches. He is corrected by Noodle, who states that he believes books to be some kind of communication tool. At that point, he believes the books are for ear-to-ear communication. He ends by saying that they are employed in eye communication.

Think About It

Question 1 . Noodle avoids offending Think-Tank but at the same time, he corrects his mistakes. How does he manage to do that?

While trying not to anger Think-Tank, Noodle also makes corrections to his errors. Every time he believes Think-Tank to be incorrect, he first extols Think-Tank before putting forward his ideas and characterizing them as mere bits of information floating around in his brain. By doing this, he informs Think-Tank of what is accurate without giving the impression that he is being corrected.

Question 2 . If you were in Noodle’s place, how would you handle Think-Tank’s mistakes?

If I were in Noodle’s place, I would try to politely correct Think-Tank’s mistakes and suggest corrections.

Question 3 . Do you think books are being replaced by electronic media? Can we do away with books altogether?

Yes, books are being replaced by electronic media with the emergence of digitization. We now have e-books and online classes, which do not require paperback books. No, I don’t think that we can do away with books altogether because although there is a tendency to move towards electronic media, books still have their importance. Millions of people love to read books. The feeling and satisfaction of reading a book while holding it in your hands and turning its pages is altogether a different experience that e-books will never be able to replace.

Question 4 . Why are books referred to as a man’s best companion? Which is your favorite book and why? Write a paragraph about that book.

Books are said to be a man's greatest friend since they mentor, educate, amuse, grieve, provoke reflection, and help us grow into better versions of ourselves. Books are lifelong friends who never leave us. They transmit wisdom and knowledge. They may inspire us, teach us, and be enjoyable.

Talk About It

Question 1 . In what ways does Think-Tank misinterpret innocent nursery rhymes as threats to the Martians? Can you think of any incidents where you misinterpreted a word or an action? How did you resolve the misunderstanding?

Answer: Think-Tank misinterprets innocent nursery rhymes as threats to the Martians.

Omega reads the lines from the rhyme: “Mistress Mary, quite contrary, How does your garden grow? With cockle shells and silver bells And pretty maids all in a row” Listening to the above lines, Think-Tank thinks that people on Earth are so advanced that they can grow crops of rare metals and high explosives. Iota reads another rhyme from the book: “Hey, diddle diddle! The cat and the fiddle, The cow jumped over the moon, The little dog laughed to see such sport, And the dish ran away with the spoon.” After reading the passage above, Think-Tank believes that humans have imparted space travel and musical culture to their tamed animals. Their pets are humorous as well. Oop reads lines from another rhyme: “Humpty Dumpty sat on the wall, Humpty Dumpty had a great fall…” After hearing this, Think-Tank becomes alarmed since Humpty-Dumpty's picture matches Think-Tank's powerful balloon brain. He believes that Earthlings are pursuing him because they have seen him. He suggests that the people on Earth have plans to seize both him and Mars Central Control.

Question 2 . The aliens in this play speak English. Do you think this is their language? What could be the language of the aliens?

Since they are unable to comprehend the words in the book Mother Goose, I do not believe that English is their native tongue. They interpret the words as codes composed of tiny dots, squiggles, and lines.

Finding the Book that Saved the Earth Question and Answers

Noodle is a very smart character who handles Think-Tank with great care. He does not want to make his boss angry, so he fixes Think-Tank's mistakes very softly. He often says his own ideas are "not important" so that Think-Tank feels like he thought of it first.

Why Books are a Man’s Best Friend

Books are called a man's best friend because they never leave us. They teach us, help us, and keep us happy even when we are alone. Books pass down good ideas over many years and help us become better people by giving us constant knowledge.

Paper Books vs. Computers

Today, things like e-books are taking the place of paper books, but reading a real book is still special. Digital books are good for nature because they save trees. However, the feeling of holding a real book and turning the pages is something a computer cannot do.

What Kind of Person is Think-Tank?

Think-Tank is a show-off leader with a very big head that looks like a balloon. He thinks he is the smartest person in the whole universe. In the end, his pride is his weakness, and he runs away to Alpha Centauri because he is scared.

The Martian team lands in a library but they have no idea what it is. They think it is a barn for animals or a sandwich shop, which shows how silly the Martians are.

Captain Omega and the Crew

Captain Omega is the leader of the team on Earth. Along with Lieutenant Iota and Sergeant Oop, they follow Think-Tank's strange orders. They even try to eat a book because he told them it was a "sandwich."
