You come home one night to find your apartment door unlocked and the apartment in a state of complete disarray. Since you left it in good condition, you assume that your roommate, who has a tendency to be messy and inconsiderate, has yet again made a mess and not bothered to clean it up. You know that if your hypothesis is correct your roommate must have come home at some point after you left. You find that the coat he was wearing when you dropped him off at work this morning is now hanging in the closet, indicating that he has indeed been home since both of you left the apartment this morning. From this evidence, you conclude that there can be no other explanation for the mess. Which of the following accurately describe the connection you make between your hypothesis and your evidence? Check all that apply.

a. You are committing the fallacy of affirming the consequent.
b. You are claiming that, because several implications of your hypothesis are true, your hypothesis itself is also necessarily true.
c. You are formulating your hypothesis from the evidence at hand, which is an infallible way to arrive at a conclusion.
d. Since your roommate is messy, your hypothesis is undoubtedly correct.
