Chapter 6 the first line of Question 8 (only) Web does not match the (Kindle [only?]) book. Unfortunately, since the choices and the answer match, it's likely why I didn't catch this earlier (as previously discussed here). Sorry.
(As previously discussed [especially if you are looking at my attachments as a point of comparison], Kindle answer options [and numbers] have always been an issue. Kindle-ers, I encourage you to please make your own report [maybe they want to hear from many of us before they act].)
