English Vocabulary — Choose the best synonym (same meaning). Target word: dimension

Introduction / Context:
“Dimension” in technical drawing, engineering, and general English refers to a measurable extent such as length, width, or height, and more broadly to a measurement or aspect. The task is to pick the closest synonym among the options.

Given Data / Assumptions:

• Target: dimension.
• Options: compass, ruler, inch, measure, diagram.
• We assume the general dictionary sense: a measurable extent/size or an aspect that can be measured.

Concept / Approach:
Map each option's part of speech and meaning to “dimension.” A good synonym should reflect “measurable extent” or “measurement,” not a tool, unit, or illustration.

Step-by-Step Solution:

Verification / Alternative check:
Usage test: “What are the dimensions of the room?” → “What are the measures/measurements of the room?” This stays natural. Replacing with “compass,” “ruler,” “inch,” or “diagram” breaks meaning or grammar.

Why Other Options Are Wrong:

• compass: instrument for arcs/circles; not the idea of extent.
• ruler: measuring tool; not the measurement itself.
• inch: a unit, not the concept of measurement.
• diagram: a drawing or schematic, not a measurement.

Common Pitfalls:
Confusing the tools of measurement with the result (dimension). Also, mistaking a unit for the general concept.

Final Answer:
measure
