Q: Given the tasks P, Q, R, and S, if P must be done before Q and R, and S can be done at any time, which of the following is a possible order of completion?
Solution: The order P, Q, R, S respects the dependency of P on Q and R.
Steps: 6
Step 1: Identify the tasks: P, Q, R, and S.
Step 2: Understand the dependencies: P must be completed before Q and R.
Step 3: Note that S can be completed at any time, with no dependencies.
Step 4: Determine a possible order of completion that respects the dependencies.
Step 5: One valid order is to complete P first, then Q, then R, and finally S.
Step 6: Verify that this order follows the rules: P is done before Q and R, and S is done last.
