Sara: Did you hear that space agencies are seriously researching nuclear thermal propulsion for human missions to Mars?
Ken: Nuclear rockets? Isn't launching radioactive reactors into orbit far too dangerous?
Sara: ----
Ken: Ah, that makes a big difference. Activating the reactor only after reaching deep space virtually eliminates terrestrial contamination risks.

- A)Engineers plan to test the live reactor by dropping it onto populated coastal cities.
- B)Nuclear thermal rockets explode intentionally during launch to propel the capsule into orbit faster.
- C)Spacecraft do not use fuel; they are pulled across the solar system exclusively by planetary magnetic cables.
- D)The reactor remains completely non-radioactive and cold during liftoff; it is only activated once the craft is in a safe interplanetary trajectory.
- E)Radiation has zero effect on biological organisms or aerospace electronic hardware.

Doğru cevap: D) The reactor remains completely non-radioactive and cold during liftoff; it is only activated once the craft is in a safe interplanetary trajectory.
Çözüm: Ken'in "activating the reactor only after reaching deep space" ifadesi, Sara'nın fırlatma anında reaktörün pasif kaldığı açıklamasını tamamlar. Doğru cevap D'dir.
