Analogy: Nightingale is to Warble as Frog is to ____. Identify the characteristic sound associated with the animal.

Introduction / Context:Animal–sound analogies pair creatures with their distinctive vocalizations. Nightingales are famed for melodious “warbling.” We must choose the sound typically associated with frogs.

Given Data / Assumptions:

• Nightingale → warble (melodious trills).
• Frog → characteristic call in common usage.
• Options present various sounds linked to different animals.

Concept / Approach:Frogs are commonly said to “croak.” The mapping is “animal : canonical sound.”

Step-by-Step Solution:Identify parallel: nightingale : warble.Select frog : croak to match the same relationship.Check distractors: yelp (often dogs/foxes), cackle (geese/hens), squeak (rodents/hinges).

Verification / Alternative check:Substitution: “As a nightingale warbles, a frog croaks.” The pair preserves “species : signature call.”

Why Other Options Are Wrong:Yelp: canine-like; cackle: poultry-like; squeak: rodents or mechanical sounds. None is the standard frog sound.

Common Pitfalls:Overthinking with less common onomatopoeias; stick with mainstream associations used in exams.

Final Answer:Croak.
