Complete the sentence: The scientist's findings were so ____ that no one could dispute them.

  • A. ambiguous
  • B. conclusive
  • C. tentative
  • D. obscure

Explanation

If nobody can dispute the findings they must be decisive, which is what conclusive means. Ambiguous, tentative and obscure all point in the opposite direction and would invite dispute rather than end it. The words following so and that always define the quality needed.
