I believe this question has been posted h(100) + 1 times!

Remember, you can use the search function to see if a question has already been addressed.

You are right Stuart, this Q is so infamous, actually in one of the runs(I think gmatprep is not trully random, just have 2-3 seeds, more or less for a given performance the order is same) it is 3rd question, and most of the people get stuck and just looks for internet to type this Q out.
Charged up again to beat the beast :)
