sample sol concern (all 12)

Never mind, There is no mistake in the sample solution. In the clarifications:

>unblock any sleeping processes >unblock any processes waiting for all their spawned processes (children) to terminate >unblock any completed I/O >commence any pending I/O >commence/resume the next READY process >otherwise the CPU remains idle...

This means that each time the CPU is idle, we only unblock the processes that can be unblocked AT THAT TIME. If anything becomes unblocked, we commence the running of the next process in the ready queue. We do not check again if anything can be unblocked despite the system time increasing. We only check if anything can be unblocked the next time the CPU is idle.
