Analogy — Supports vs suppresses combustion: Oxygen : Burn :: Carbon dioxide : ? Pick the effect that carbon dioxide has with respect to fire.

Difficulty: Easy

Correct Answer: Extinguishes

Explanation:


Introduction / Context:
Oxygen supports burning; carbon dioxide suppresses it. Therefore, “Extinguishes” best mirrors the complementary combustion effect.



Why Other Options Are Wrong:

  • Isolate/Foam: Not direct verbs of fire’s fate; foam is a substance, not an effect.
  • Explode: Opposite implication.
  • None of these: Invalid since “Extinguishes” is standard in fire safety.


Final Answer:
Extinguishes
