Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

21. Limited volume production (a set number of items to be produced)






22. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani
