Q: Given the constraints that task X must be completed before task Y and task Z cannot start until task Y is finished, which of the following is a valid sequence?
Solution: The sequence X, Y, Z respects the constraints that X is before Y and Y is before Z.
Steps: 5
Step 1: Identify the tasks involved: X, Y, and Z.
Step 2: Understand the constraints: Task X must be completed before task Y can start.
Step 3: Note the second constraint: Task Z cannot start until task Y is finished.
Step 4: Determine the order of tasks based on the constraints: Since X must be done before Y, and Y must be done before Z, the only valid sequence is X, Y, Z.
Step 5: Confirm that the sequence X, Y, Z meets both constraints: X is before Y, and Y is before Z.
