Assume that at time 5 no system resources are being used except for the processor and memory. Now consider the following events:

- At time 5: P1 executes a command to read from disk unit3

- At time 15: P5s time slice expires

- At time 18: P7 execute a command to write to disk unit 3

- At time 20: P3 execute a command to read to disk unit 2

- At time 24: P5 execute a command to write to disk unit 3

- At time 28: P5 is swapped out

- At time 33: An interrupt occurs from disk unit 2: P3s read is complete

- At time 36: An interrupt occurs from disk unit 3: P1s read is complete

- At time 38: P8 terminates

- At time 40: An interrupt occurs from disk unit 3: P5s write is complete

- At time 44: P5 is swapped back in

- At time 48: An interrupt occurs from disk unit 3: P7s write is complete

* For each time 22, 37, and 47, identify which state each process is in. If a process is blocked, further identify the event on which it is blocked.
