the ring was fixed and the shaft could move.

A lot of the questions were ambiguous though, and could have multiple
interpretations. I got lucky there, because the alternate (or more
correct) answer wasn't one of the options.

One of the lever questions was just plain wrong, IMHO.

98% here also, I got nunber 7 wrong regarding the drive types. I
reviewed the questions and didn't understand what the result for 7
indicated. Like you and a number of others I though a number of those
question were ambiguous.
