(E) states that "Fleure left the third and fourth messages."
This gives us: __ __ F F P __ 1 2 3 4 5 6
From Rule #6, we know that since we have P in, we also need to put H and L on the list with H preceding L. From Rule #3, we know that H cannot be in the first spot.
This gives us: __ H F F P L 1 2 3 4 5 6
However, Rule #5 tells us that since F left a message, P and T both did, with that of P preceding that of T. We already have P on our diagram, so all we need to do is include T after it. However, the only open spot is Spot 1, which is before P. Therefore, (E) is incorrect.
Does that make sense? Please let us know if you would like an explanation of any of the other answer choices or have any additional questions!
