Q: In a scheduling set involving five tasks A, B, C, D, and E, if task A must be completed before task B, and task C must be completed before task D, which of the following is a valid sequence?
Solution: The sequence A, B, C, D, E respects the constraints that A is before B and C is before D.
Steps: 6
Step 1: Identify the tasks involved: A, B, C, D, and E.
Step 2: Understand the constraints: Task A must be completed before Task B, and Task C must be completed before Task D.
Step 3: Write down the constraints: A -> B and C -> D.
Step 4: Create a sequence of tasks that respects these constraints.
Step 5: Check the sequence A, B, C, D, E: A is before B (valid) and C is before D (valid).
Step 6: Conclude that the sequence A, B, C, D, E is a valid sequence.
