Answer choice

I’m happy to help. As always, let’s start with the question stem. It is a must be true question. In order to know what must be true, we have to understand the argument: If B, A, and L ==> B -> A (contrapositive not A -> not B) AND L -> not B (contrapositive B -> not L) Remember, we know that bankers, athletes, and lawyers are all present. So there will be at least one banker, and we know from rule 1 that that banker is also an athlete. And we know from the contrapositive of rule 2 that that banker is not a lawyer. So at least one athlete is not a lawyer, which is answer C. E is incorrect because we could hypothetically have a lawyer who is an athlete and that wouldn’t violate any of the rules or contrapositive, so “none of the lawyers are athletes” need not be true. I hope that helps! Please let us know if you have further questions.
