Finding nonclassical counterexamples

Here is a random argument! (Premises above the line; conclusion below it)

  • b
  • x → ((¬z → q) → (k ∨ e))
  • ---------------
  • e

Give a counterexample to this argument in the FDE matrix, if there is one!

Note that the matrix can change from one argument to the next, so stay alert!
