Sound-category identification: “Squeak : Hiss : Howl” — select the option that best describes the trio’s shared nature.

Introduction / Context:
“Squeak,” “Hiss,” and “Howl” are onomatopoeic or descriptive labels for vocalizations or sounds made by animals. The item tests recognition of a semantic category rather than recalling specific species.

Given Data / Assumptions:

• Squeak → rodents/bats/objects; in animal context, a small, high-pitched call.
• Hiss → snakes, cats (warning sound).
• Howl → wolves, dogs (prolonged vocalization).

Concept / Approach:
Identify the shared nature: these are animal-produced sounds, not animals themselves, currencies, or size descriptors.

Step-by-Step Solution:
1) Extract the semantic type of each term: sound.2) Determine the producer: animals.3) Choose the category description that matches precisely.

Why Other Options Are Wrong:

• Names of animals/currencies/biggest animals/weather events: Incorrect semantic classes.

Common Pitfalls:
Confusing the sound with the animal that produces it. The category is the type of word (sound), not the producer itself.

Final Answer:
They are sound produced by animals
