Then there's just outright "stupidity". DS, my math guy answered a question about what someone was most likely to
dictate with
population, because he saw virtually no point in writing down just one
letter....you know, a. Or maybe b. Or perhaps c. ROFL!
That test writer above though obviously doesn't appreciate the fine gourmet of a good mud pie either,

! Yup, I'd say "E" (or "C"?) is smarter than the writers on that one!
When my kids do answer something wrong, it's always entertaining to listen to their reasons.
