Document Summary
Justify your answer by symbolizing the following argument in sl (using the suggested sentence letters) and constructing a derivation that shows that the symbolic argument is valid in sd or sd+. The maid did it or the cook did it unless the butler did it or the gardener did it. If the maid did it, then it was done silently; but, if the cook did it, then it was done quickly. However, it was done neither silently nor quickly. The gardener did it if and only if it was done with a rope. If it was done with a rope, then it was not done quickly. On the other hand, if the cook did it or the butler did it, then a pistol was the weapon. But, if a pistol was the weapon, then it was not done silently. It was not done with a rope.
