Answer Key with Explanations
1. C – All marine life vanishes from the reef after a violent quake. Phoebe notes this eerie silence as the first sign of danger (Chapter 1).
2. B – They flee to a secret garage bunker and escape in armored Titans. Seichan and Gray evacuate the villa when the attack begins (Chapter 2/4).
3. A – A vast bioluminescent coral forest. The Cormorant descends into a forest that dwarfs any known formation (Chapter 14).
4. D – Tse wants to silence witnesses to the Changzheng 24 disaster and prove the value of autonomous systems. She personally orders the destruction and later commands from the Dayangxi (Chapter 20 evidence).
5. B – Valya escapes with it under triad protection after a double‑cross. The exchange turns violent, and Valya flees with the box (Chapter 18).

7. B – The coral contains orthorhombic crystals matching those in petrified sailors and in lunar dust from Chang’e‑5. Heng discovers this with the SEM (Chapter 23).
8. B – Gray broadcasts a bullroarer recording from the Titan X, which calms the eruptions and guides the bioluminescent polyps to open a portal for the Cormorant to surface (Chapter 44).
9. B – She fears that her past as an assassin will put Jack in danger. On the balcony, she explains her hesitation to Guan‑yin (Chapter 2).
10. B – A promise to her dying father about a great destiny. During the descent, she recalls his words (Chapter 35 evidence).
