Which term best describes a full-scale working model used to test a concept or design concept by making observations and adjustments?

• A. Prototype
• B. Concept
• C. Model
• D. Diagram

Answer: (A)

The concept being tested is a working, full-scale version built to try out a concept in real conditions and make adjustments based on what’s observed. A prototype fits this purpose because it is an actual, functional model used to test how the design performs, identify problems, and refine the concept before final production or implementation. A concept is just an idea, not a tangible, tested version. A diagram is a drawing or plan, not a working entity. A model is a representation that may be simpler or non-functional, not necessarily something you can operate to observe real behavior. Thus, the best term for a full-scale, observational, adjustable test version is prototype.
