Okay, I'm embarrassed, but I don't really see anything terribly wrong with these questions. And I think it was a funny story.
I think there was sufficient information in the amusing tale to answer the questions correctly. Ha ha ha, at least *I* got them all right, so perhaps that's why I think they were fine :-)
So many reading comprehension stories are incredibly boring--I would think the students would be glad to read something intended to be comical. And they should be able to analyze this type of reading, and get the joke.
PS Colinsmum , I hope you are right that Deborah Meier made that mistake, and I think your assumption it is more logical!
