Answer Key

Plot / Sequence

  1. c – Ye Wenjie witnesses the Red Guards beat her father Ye Zhetai to death during a struggle session (Chapter 2).
  2. Hairen – Wang Miao uses the name Hairen when he first logs into the Three Body game (Chapter 8).
  3. Operation Guzheng – The plan to string nanofilaments across the Gaillard Cut to slice Judgment Day (Chapter 32).
  4. c – The Trisolaran listener, knowing his civilization will exploit Earth, sends the warning “Do not answer!” (Chapter 33).
  5. A red waveform appears in the cosmic microwave background data from all satellites and ground observatories – This confirms the universe is flickering, which Wang decodes as a Morse countdown (Chapter 10).
  6. c – At the ETO meeting, Ye Wenjie accuses Pan Han of intercepting Trisolaran messages and orders his execution (Chapter 22).
  7. Project Sophon – Trisolaris unfolds a proton into a two-dimensional plane to etch circuits, creating a superintelligent computer that can lock human science (Chapter 34).
  8. The countdown appears on every frame of film he develops after a photography outing – No defect is found; the numbers vanish only when he stops his nanomaterial research (Chapter 7).

Character Motivation

  1. Ye Wenjie believes humanity cannot solve its own problems and wants a superior alien civilization to conquer Earth and impose order. (Chapter 24)
  2. c – After initially refusing, Wang is provoked by Shi Qiang and moved by General Chang’s warning that humanity’s “long run of good fortune has ended.” (Chapter 5)
  3. Conventional weapons cannot prevent the crew of Judgment Day from destroying the Trisolaran data; nanofilaments can slice the ship instantly, killing everyone before they can react. (Chapter 32)
  4. c – Wei Cheng felt useless in academia, could not keep a job, and sought a quiet place to think. The abbot’s advice about “emptiness” led him to the three-body problem. (Chapter 17, cited from evidence)
  5. Shen Yufei recognized his mathematical talent for solving the three-body problem, and the marriage was one of mutual convenience – she funded his research, and he worked on the problem. (Chapter 17, evidence from the novel)

Theme / Symbol

  1. b – The hypotheses illustrate that physical laws may be local and contingent, not universal – a “shooter” may create a target pattern that seems like a law to the targets, and a “farmer” may kill the chickens who have come to expect food. (Chapter 7)
  2. It represents Trisolaran civilization’s defiance against chaos and its eternal struggle for order in an unpredictable universe. The pendulum is described as “a gigantic metal fist, swinging eternally against the unfeeling universe.” (Chapter 20)
  3. The metaphor suggests that although Trisolarans see humans as insignificant “bugs,” bugs have never been defeated despite millennia of extermination, symbolizing human resilience and the possibility of survival. (Chapter 35)
  4. b – The Dark Forest theory holds that any civilization that reveals its location will be destroyed, so silence is the only safe strategy. (Chapter 51)

Synthesis

  1. The Cultural Revolution’s violence and persecution directly cause Ye Wenjie’s loss of faith in humanity. Witnessing her father’s murder and later having her last hope for human repentance denied (when the Red Guards refuse to apologize) drives her to contact Trisolaris and invite invasion, setting the entire plot in motion. (Chapters 2 and 27)
  2. Ye Wenjie, traumatized and alienated, actively initiates contact with Trisolaris and becomes the leader of the Earth-Trisolaris Organization, betraying Earth. Wang Miao, a nanotech engineer, is reluctantly drawn into the investigation, helps expose the conspiracy, and his nanomaterial enables Operation Guzheng. Both are scientists, but Ye’s motivation is ideological despair, while Wang’s is duty and curiosity; their actions represent two sides of humanity’s response to the unknown. (Chapters 2, 5, 25, 32)
  3. The novel portrays science as both fragile and resilient. The sophon blockade shows that a superior civilization can shut down fundamental research, causing despair (as seen in Yang Dong’s suicide). At the same time, creativity persists – Wei Cheng’s evolutionary algorithm, Wang’s nanomaterials, and the human determination to fight back. The story questions whether technological progress always benefits humanity and highlights the emotional and existential costs of scientific collapse. (Chapters 6, 17, 34, 35)
