Difficulty: Medium
Correct Answer: Ghee
Explanation:
Introduction / Context:
Some analogies rely on a “source to derived fatty product” relation. In household and industrial contexts, waxes and greases are closely associated as lipidic, semi-solid materials used for lubrication and protection; likewise, ghee is a clarified fat derived from milk. We apply that source→fatty derivative mapping here.
Given Data / Assumptions:
Concept / Approach:
Interpret “Wax : Grease” as “lipidic base material : thicker fatty derivative used for lubrication.” By analogy, “Milk : Ghee” follows “nutritive base fluid : clarified lipid derivative.” While milk also yields curd (a fermented protein-rich product), the closest parallel to a fatty/semi-solid derivative is ghee rather than curd or the generic category “protein.”
Step-by-Step Solution:
Verification / Alternative check:
Curd is primarily a coagulated protein matrix (casein) from milk souring, not a fat-dominated derivative. Ghee, however, is expressly the fat fraction refined from dairy, which mirrors the lipid emphasis of grease in the first pair.
Why Other Options Are Wrong:
Common Pitfalls:
Equating “any derivative” instead of matching the type of derivative (fatty vs. protein). Always preserve the nature of the outcome in analogies.
Final Answer:
Ghee
