English Language & Literature — CBSE Class 10 board question

In The Book That Saved the Earth, Claire Boiko uses humour and irony cleverly to mock both futuristic technology and misplaced human (or Martian) arrogance.

Humour through misinterpretation: Think-Tank, despite calling himself "the most powerful and intelligent creature in the whole universe," cannot identify a book. He mistakes it for a sandwich, orders Sergeant Oop to eat it, and then calls it a "communication device" — each blunder funnier than the last.

Irony of advanced intelligence: The very vitamins meant to boost the Martians' intelligence cause them to over-interpret a harmless nursery rhyme. "Mistress Mary" convinces Think-Tank Earth grows silver and explosives; "Hey Diddle Diddle" suggests an army of cows; "Humpty Dumpty" makes him flee the entire solar system.

Message through nursery rhyme: The author conveys that arrogance and assumption are more dangerous than ignorance. Think-Tank's ego blinds him — he refuses to admit error and instead builds terrifying conclusions on childish verses. The play suggests that true intelligence lies in admitting what you do not know — something Noodle quietly demonstrates throughout, eventually replacing Think-Tank as leader.

Examiners look for three things in a 6-mark answer like this:

1. Textual evidence — cite actual nursery rhymes and scenes (Sergeant Oop eating the book, Humpty Dumpty panic, etc.)
2. Literary terms — name the humour and irony as asked; don't just retell the plot.
3. Message/theme — close with a clear thematic statement (arrogance vs. true wisdom, Noodle replacing Think-Tank).
