"I Aced Archaeological Anthropology! (but I can't pass a fifth grade spelling test.)"

I was reading my textbook for a quiz in my general archaeology class when I came across this. I thought it was a little pathetic and also very ironic. The word "scientifically" is misspelled...in a science book. That is hilarious. It makes me wonder if the author of this textbook had an editor. If he/she did, they were a god-awful one. I question the reliability of this textbook. Seriously.

Correction: Get an editor or fire the one you have now and get a new one! I would assume, since this author has a PhD, that they would know how to spell the word "scientifically"(at least I hope, but who knows nowadays?).
