Hi bender1227,

To start, you should try posting this question in the PS Forum here:

https://gmatclub.com/forum/gmat-problem-solving-ps-140/

Since it's not clear if this question is properly 'formatted' or not, I would suggest that you write this question on a piece of paper and upload the image (so that we can clearly see what the question is asking.

GMAT assassins aren't born, they're made,
Rich
