which one is more representative of the real GMAT ?

Recent reports from test takers show that most people see 4 passages on test day, with 4 questions on each of the first 2 passages and 3 questions on each of the last 2 passages. It's possible that you'll only see 3 passages on test day, in which case one of your passages may have 5 questions.

However, even though you'll only see 3-5 questions per passage, each passage actually has a pretty big pool of questions (so the test can continue to adapt to your performance). Most (if not all) of those questions appear in the OG.
