Analogy — Determinant relationship in domains: Market : Demand :: Farming : ? Choose the factor that most directly determines or drives the success of “Farming”, analogous to “Demand” driving a “Market”.

Introduction / Context:
In “Market : Demand”, demand is the primary driver that influences market size, price movement, and activity. The task is to pick the analogous driver for farming outcomes.

Given Data / Assumptions:

• “Market → Demand”: demand is a principal determinant.
• Farming outcomes depend on multiple factors; in the typical Indian context, seasonal rainfall/monsoons are a key driver.
• We seek a similarly dominant, causal determinant.

Concept / Approach:
Preserve “domain → chief driver” symmetry. Demand drives markets; monsoons (rainfall) drive agricultural yield/planting success in large rain-fed regions.

Step-by-Step Solution:

Verification / Alternative check:
Consider production volatility: poor monsoons reduce yield and acreage, mirroring weak demand reducing market activity.

Why Other Options Are Wrong:

• Farmer: Agent, not a climatic determinant.
• Foodgrain: Output, not a driver.
• Soil: Important baseline factor, but monsoon variability more directly explains year-to-year outcomes in rain-fed systems.
• None of these: Invalid since “Monsoons” fits.

Common Pitfalls:
Confusing actors or products with causal environmental drivers.

Final Answer:
Monsoons
