Which one is not correct for a productive theory?

Correct answer: C. It discourages suggestion of different hypotheses

  • A. It is predictive
  • B. It has explanatory power
  • C. It discourages suggestion of different hypotheses
  • D. None of these

Explanation

A productive scientific theory makes predictions, explains observations and stimulates new questions and hypotheses for testing. Therefore, it should not discourage different hypotheses; students may choose “none of these” if they overlook that option c directly contradicts the creative and testable nature of scientific theories.
