"Resistance is to the opposition as the advantage is to_____."

The analogy presented in the question compares "resistance" to "opposition" and asks for a similar relationship with "advantage."

The word that completes the analogy is "benefit." An advantage is a favorable condition or circumstance, and a benefit is something that provides an advantage.

Final Answer: benefit
