When you can see the results, it's easier...

Q7 (which geartrain is which) is just plain wrong. Even allowing for
crazy Yankee terminology, there's no way that the one train of three
pinions (the others are all 2) can be "reverse". That's not mechanical
aptitude, that's assuming that you're looking inside a RWD car gearbox
(where the extra idler gear is indeed used for reverse) -- but then
"direct drive" in that context wouldn't be using any of the gears.

Q45 The balloons are another bad question. Three balloons illustrated
as being next to each other? Of course the atmospheric pressure is
identical (Pascal's principle, if you care), it's far more likely that
they're made of thicker rubber than there's some sort of barometric
change across the page.


I agree. They are the two I got wrong.
