Unless you submit the form, your application will be rejected. Your application was not rejected. Which conclusion follows?

  • A. You submitted the form
  • B. You did not submit the form
  • C. The form was lost
  • D. Nothing follows

Explanation

Unless means if not, so the statement says that not submitting leads to rejection, and since rejection did not occur, the form must have been submitted. Rewriting unless sentences as if not is the reliable way to handle them. This is modus tollens applied to the rewritten conditional.
