So in rule 2 it says she cannot select the H unless she selects the K. If she selected the K, why isn't A the answer?

    Hi @alisonm3, Thanks for the question! So saying that she can’t pick H unless she picks K doesn’t mean that she picks K necessarily in this question. Remember, we diagram X unless Y as ~Y —> X, which means this can be diagrammed ~K —> ~H or H —> K so if she had picked H, she would’ve picked K. But say she picks K, she can still pick or not pick H. And that’s why the correct answer doesn’t have to have H in it. Hope this helps! Feel free to ask any other questions that you might have.
