I just took some practice test from Baron's, and I found a number of problems as I was taking it with typos. When I was done correcting my test, I went back to look at which ones I had gotten wrong, and I swear that some of the answers they gave are NOT right. I vaguely remember someone saying something about a catalyst question from barons that was also on the Kaplan test and how they had different answers...was it beagle?? Anyways, for clarifications sake, I have a couple of questions for whoever thinks they know them: 1) Which of the following vessels carries oxygenated blood? A) Pulmonary Artery B) umbilical Artery C) thoracic duct D) umbilical vein E) hepatic vein The key says 'A', but I learned the night before in my kaplan lecdture that the umbilical vein carries oxygenated blood. I also remember that from a physiology class. Which of you biology majors out there knows the answer? There were a couple of other bad questions, but I think I got 'em figured out. Thanks for all of your help and support!
