Finding nonclassical counterexamples

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

  • x
  • ¬¬e
  • ((p ∨ p) → o) → g
  • ---------------
  • c → ((m → a) ∧ ¬⊤)

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

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