English Vocabulary — Choose the best associated meaning/definition. Target word: dome

Introduction / Context:
A “dome” is an architectural element shaped like a hollow upper half of a sphere (or similar curved surface). When a direct one-word synonym like “cupola” is not offered, the best option is the adjective capturing the essential form: rounded/curved.

Given Data / Assumptions:

• Target: dome.
• Options: rounded, geodesic, governmental, coppery, steeple.
• We want the option that best captures the core defining property.

Concept / Approach:
Define the essence of “dome”: a curved, rounded roof/ceiling form. “Geodesic” names a specific dome subtype; “governmental” and “coppery” are incidental associations (who uses it, what it is made of). “Steeple” is a different architectural element (tall, pointed tower).

Step-by-Step Solution:

Verification / Alternative check:
Definition match: “A dome is a rounded vault forming the roof of a building.” The descriptive keyword “rounded” reproduces the essential geometry.

Why Other Options Are Wrong:

• geodesic: a specific structural system (triangular network) used to form certain domes; not a synonym.
• governmental: many capitols have domes, but this is contextual, not definitional.
• coppery: some domes are copper-clad; material is incidental.
• steeple: tall, slender, often pointed tower; different form.

Common Pitfalls:
Choosing a subtype or a common association instead of the defining shape; confusing steeples with domes.

Final Answer:
rounded
