So this question is easy enough when I take a moment to write out the logic. Even so, I'd like some advice on how to attempt this without enough time to parse out and write down the logic of each answer choice until I get to the right one. Unless the rule of thumb is, just write it out. In which case, I'll continue to do so.
Thanks!
