Analogy — Cause and typical effect: Liquor : Intoxication :: Medicine : ? Select the usual, intended effect that parallels “liquor causes intoxication”.

Introduction / Context:
Liquor leads to intoxication. The medical parallel is “medicine leads (ideally) to cure”. Both are canonical cause→effect pairings.

Why Other Options Are Wrong:

• Engine : Fuel — Reversed dependency; engines consume fuel.
• Whisky : Alcoholic — Category confusion; “alcoholic” is a person-dependent descriptor.
• Bottle : Cork — Container and closure; not cause→effect.
• None of these — invalid because “Medicine : Cure” fits.

Final Answer:
Medicine : Cure
