i got fifteen. i also have a few issues with it...
1. i am not an american, i know very little about american trivia
2. fan rotation depends on how you wire them. their fan question was not precise.
3. there is no "standard" size bag of hot dog buns. my "standard" is a bag of 12.
4. i have owned a set of venetian blinds and the cord was on the right hand side, not the left
5. i have been on a merry-go-around, and it went both ways...
I think they were talking about normal everyday household fans (that's the way most people would look at it, I think). Not the ones that electricians (like yourself) go around modifying.
Standard bags of hot dog buns in the US is 8.
Maybe the blinds you had were not actually venetian blinds.
The Merry-Go-Rounds I've been on went clockwise, the test said they go counter-clockwise.
The fourth time I took the test I got a much better score.
