Answer

Answer:

  1. d. cleavage/fracture
  2. b. Color

Brief Explanations:

  1. The diagram shows a mineral being struck with a hammer to observe how it breaks, which tests cleavage/fracture.
  2. Color can vary greatly due to impurities and is the least reliable for mineral - identification compared to streak, specific gravity, and hardness.
