Consider the following statements about formula selection.
1. A formula performs best near the conditions it was fitted to.
2. Existing tolerance data ties an industry to its chosen formula.
3. The newest formula is always the right choice for any application.

  • A.1 only
  • B.All of them
  • C.1 and 2 only
  • D.3 only

Answer: C

Correct answer: 1 and 2 only

Statements 1 and 2 are the two real considerations: a formula fitted on textile data at moderate chroma performs best there, and an industry with years of tolerance data has a substantial cost in changing. Statement 3 ignores both - adopting a newer formula means revisiting every tolerance that was set with the old one.
