Producer–product analogy: “Silkworm : Silk :: Snake : ?” — identify the corresponding output/produced substance.

Introduction / Context:
The relationship is organism → characteristic product/substance. A silkworm produces silk; a snake produces venom (colloquially called poison, though “venom” is more precise in biology).

Given Data / Assumptions:

• Silkworm → silk (material).
• Snake → venom (termed “poison” in many GK items).

Concept / Approach:
Select the term that mirrors the output relationship.

Step-by-Step Solution:
1) Identify “product” of snake in common usage: poison (venom).2) Choose “Poison.”

Why Other Options Are Wrong:

• Poisonless: Negation, not a product.
• Death/Fear: Effects, not a substance produced.
• Skin: Shed by many animals; not the standard product analogy here.

Common Pitfalls:
Over-correcting from “poison” to biological “venom”; in GK analogies, “poison” is acceptable shorthand.

Final Answer:
Poison
