Questions & Step-by-Step Solutions

If tasks P, Q, R, and S are scheduled such that P must be completed before Q, and R must be completed before S, which of the following is a possible order?

Step 1: Identify the tasks: P, Q, R, and S.
Step 2: Understand the constraints: P must be completed before Q, and R must be completed before S.
Step 3: List the possible orders of tasks while respecting the constraints.
Step 4: Check the order P, Q, R, S: P is before Q (satisfied) and R is before S (not included in this order).
Step 5: Realize that R can be placed before S in any order as long as P is before Q.
Step 6: Conclude that the order P, Q, R, S is valid because it respects the constraints.
