What is the difficulty level of the last few reading comprehension questions in OG13 ? (pages 410 - 416)

Thanks !

i've found that the answers to this type of question are almost never useful in preparing someone for the GMAT, so i'll decline to provide a guess as to difficulty level unless you can tell us how you will use that information to better prepare yourself for the GMAT.. :)
