There isn't a huge difference (10usecs of state transition), but clarification would be greatly appreciated.
(sorry, I can't find the original comment that identified this) Thanks for identifying this confusion. I've modified the sample solution, and added this to the Clarifications: "If a process calls the 'wait' system-call when it has no children, it should be moved from the CPU to the READY queue (not to the WAITING queue)."
