This question is from MGMAT CAT tests.Whitney Garner wrote:Received a PM asking me to respond. Don't see a source. Please cite the source (author) of the problem so I can respond!
Note to those studying this: if I were you, I would NOT read / study problems that do not have the source cited. There are several very important reasons for this:
1) If you don't know the source, then you don't know whether you are compromising your future practice tests. What if the question is from the practice test you're about to take and now you see a question that you've already seen before? When that happens, it can blow the validity of your whole test! (Not if it happens just once, of course, but what if it happens multiple times?)
2) If you're taking a practice test and do see a question you've seen before, you'll probably answer it more quickly. This will give you a false sense of timing security because you now have a little more time... but that situation will NEVER be replicated on the real test.
3) The source might be bad. Do you want to study from a bad source? I don't!
I request all BTG members to post the source of the question.
