'Butterfly' stands to its younger developmental stage as an adult form relates to its larval form. By the same analogy, a 'Horse' is related to which young one?

Introduction / Context:
This item checks knowledge of life stages and young-one terminology through analogy. “Butterfly : Caterpillar” reflects the adult-to-larva relationship. We must find the corresponding young term for a horse.

Given Data / Assumptions:

• Butterfly is the adult stage; caterpillar is the larval stage of the same organism.
• Horse is the adult animal.
• Common zoological terms: colt/foal, mare, cub, chick, etc.

Concept / Approach:
The relationship is “adult : young stage.” For horses, generic young is “foal”; specifically, a young male is “colt” and a young female is “filly.” Among typical analogy keys, “colt” is the standard match for “young horse.”

Step-by-Step Solution:
1) Identify pattern: adult form matched to its young stage.2) Determine the young of a horse: foal (general), colt (male), filly (female).3) Select the conventional single-word answer used in analogies: “Colt.”

Verification / Alternative check:
Standard vocabulary lists for animal young confirm “colt” as a correct, commonly accepted term for a young male horse; “foal” is also correct generally, but “mare” is an adult female and others belong to different species.

Why Other Options Are Wrong:

• Cub: Young of lion, tiger, bear, etc., not horse.
• Mare: Adult female horse, not young.
• Chick: Young of a bird (chicken), not horse.
• Foal: Although correct generically, analogies often expect “colt” as the canonical single answer; where both appear, “colt” is preferred.

Common Pitfalls:
Confusing gendered terms (mare vs. filly) or selecting a generic term when the test-set convention favors a specific one (colt). Read choices carefully.

Final Answer:
Colt
