That question I assumed that whatever gears were pictured *were* the
system.  I didn't think about it at the time, but now that you bring
it up it might not have been a safe assumption to make.  Luckily for
me though, that seems to be how they intended the question to be
interpreted.

I missed this one as well, for the exact same reason.

I missed question 5 (the 'do all the large gears turn at the same
speed' one) because somehow I had a total brainfart and read it as 'do
all the large gears turn the same direction'.  When I reviewed my
answers I was surprised I missed that one until I read the question
again and said "oh, sonofa...." =)

I only scored 60%, and I know that's at least part of the reason.  I
did it at work, just answering a question here or there while working
on other stuff.  I know I would've done better if I had done it in one
go and really focused on it.
