Answer Key

Part I: Plot & Sequence

  1. B) Load incendiary rounds into mortars and fire eastward. The opening chapter (“Leaflets”) describes American artillery on hotel rooftops doing exactly this as leaflets fall.

  2. B) A sheet of paper smelling of ink and gasoline. In Chapter 3 (“The Girl”), Marie-Laure finds the paper lodged in her shutters, smelling of fresh ink and gasoline.

  3. 480 bombs. Chapter 8 (“Bombs Away”) states that twelve bombers dropped 480 bombs on Saint-Malo.

  4. B) He knows he will be recommended for an elite Nazi school and must eliminate evidence of illegal listening. After fixing Siedler’s radio and earning the promise of a recommendation, Werner destroys his own shortwave to erase proof of past disobedience.

  5. B) In the miniature model house of 4 rue Vauborel. Marie-Laure discovers the stone hidden inside the model house after her father’s final letter clues her in (“inside the house twice”).

  6. Reinhold von Rumpel. The gemologist is introduced in Chapter 46 and pursues the diamond throughout the novel.

  7. A) Pouring a bucket of ice water on a tied-up prisoner. In Chapter 70, Frederick refuses three times, choosing to spill the water on the ground instead, an act of defiance that leads to his severe beating and eventual brain damage.

  8. C) She sets it in the water, letting it float away. During the cease-fire, Marie-Laure leads Werner to the grotto, unlocks the gate, and places the miniature house (with the diamond) into the sea.

Part II: Character Motivation

  1. B) He sees it as the only way to escape a future in the coal mines. Throughout his childhood, Werner fears the mines that killed his father; the Nazi school appears as his sole path to a different life.

  2. C) Joy in defiance and a refusal to passively accept occupation. Madame Manec says she has never had more fun than during her resistance activities, and the chapter title “Old Ladies’ Resistance Club” celebrates their defiant joy.

  3. To reach out for connection and comfort during the siege. Alone and terrified, Marie-Laure activates the transmitter to share a story, hoping someone might hear; she also wants to maintain the resistance broadcasting that Étienne started.

  4. B) Obligation to Hitler’s museum in Linz and personal obsession. Von Rumpel’s mission blends Nazi looting orders with his own desperate fixation on the gem, which he pursues even as his body fails.

  5. A) She suspects his motives and does not trust him. Big Claude is a known collaborator and black-marketeer who earlier informed on Étienne; Marie-Laure intuitively knows he cannot be trusted.

Part III: Theme & Symbol

  1. B) Physical destruction and technological control. The Beck quote emphasizes the ruined city; the Goebbels quote underscores radio as essential to Nazi power.

  2. A) The nature of greed and sacrifice. The Sea of Flames forces characters to weigh personal gain against the harm it brings to loved ones, a classic exploration of the cost of desire.

  3. Order, industry, and the tension between natural beauty and mechanized war. Bees recur as symbols of communal labor and also appear on the hotel’s emblem, contrasting the natural world with the destructive “hive” of the Nazi war machine.

  4. B) The way memory and connection persist beyond death. Marie-Laure imagines the souls of her loved ones traveling on electromagnetic waves, suggesting that invisible forces keep them alive in her memory.

Part IV: Synthesis & Analysis

  1. Sample answer: The novel uses radio waves—invisible light—as a metaphor for human connection that characters cannot always see but that profoundly shapes their lives. For example, Werner hears the Frenchman’s broadcasts as a child and that hidden transmission inspires his scientific dreams, even though the source remains invisible. Similarly, moral light (courage, empathy) often goes unseen by characters caught in the war, yet it guides them: Marie-Laure’s father builds her a model city she can “see” through touch, an invisible light of parental love.

  2. B) The same moment can affect multiple people in widely different ways, emphasizing how war connects and divides. The chapter cuts between Volkheimer eating yams, Étienne dreaming of escape, Jutta sleeping, and Hitler at breakfast, showing that a single instant holds vastly different experiences.

  3. Sample answer: Marie-Laure keeps the diamond because it carries memories of her father and the war, not because she believes in its value or curse. As an adult malacologist, she treats it as a natural object, not a treasure. She does not sell it or display it; instead, she hides it away, and years later gives Jutta a small iron key from the model house, symbolizing that the stone’s true worth is personal and untransferable. She chooses not to flood the story with the diamond’s legend, allowing her father’s love—not the gem—to be her inheritance.
