Question

1. the productivity of a design may be established by testing a(n) ______. a. existing product b. mock-up c. prototype d. cad drawing

Explanation:

To determine the answer, we analyze each option:

• Option a (existing product): Testing an existing product might not reflect the new design's productivity.
• Option b (mock - up): A mock - up is a non - functional or partially functional representation, not ideal for productivity testing.
• Option c (prototype): A prototype is a working model of the design. Testing a prototype allows us to measure how efficiently the design can perform its intended functions, thus establishing its productivity.
• Option d (CAD drawing): A CAD drawing is a 2D or 3D representation on a computer, and it can't be tested for productivity as it's not a physical or working model.

Answer:

c. prototype
