"Hi Diane,  I don't think it is a very good question... If you read down to the 5th paragraph [in Wikipedia], "Adult hemoglobin alone actually has a higher affinity for oxygen than its fetal equivalent, but the levels of 2,3-BPG reduce it." "

Aha!  So it was a trick question.  I think everyone can rest assured, then.  Historically, at least, IBLCE doesn't go in for trick questions.  For my part, I have every intention of failing if this is the level of knowledge I need :-)
