    A and B are the same logically and there is no way for them to both be write. A is L->C, b is saying Not C-> Not L they are the exact same logically. But what happens if our society has SOME laws? you would infer that there has to be SOME crime why? because if there were no laws, there would be no crime. What is the contrapositive of that? C->L. So, is some included in all? Yes so D has to be correct.

    D is right because If a society has some crimes (1-99 crimes out of 100), then from the stimulus we can conclude that is has some laws (1-99 laws out of 100). If we have one crime, then we know there is at least 1 law that would make said action into a crime.

    B is wrong because we can still have laws without crimes. It’s confusing sufficient w necessary
    The stimulus says this:
    Crimes ——> laws
    With the contrapostive being
    /laws —-> /crimes

    Answer choice B is saying this:

    /crimes —-> /laws
