4.Why repeat a test three times?
  • A.To use more materials
  • B.One result might be a bad build rather than a bad design
  • C.To fill the lesson
5.A test shows no failure at all. What should you do?
  • A.Stop testing
  • B.Increase the load until it does, to find the limit
  • C.Declare it perfect
6.What should be recorded besides the result?
  • A.Who was fastest
