Analogy — Material source and product mapping: A : Gum :: Worm : B

Introduction / Context:
Gum is tapped from trees; silk is produced by silkworms. The analogy requires pairing each producer/source with its characteristic product.

Given Data / Assumptions:

• Gum → obtained from trees.
• Silk → produced by silkworms.

Concept / Approach:
Match “natural source → output” on both sides.

Step-by-Step Solution:

Why Other Options Are Wrong:

• Loaf/Tread, Bottle/Insect, Brand/Cocoon — mismatched or not “source → product”.
• None of these — incorrect because a correct pairing exists.

Final Answer:
A. Tree, B. Silk
