Questions & Step-by-Step Solutions
Given the tasks A, B, C, D, and E, if A and B must be done before C, and C must be done before D, which of the following is a possible order of completion?
Step 1: Identify the tasks: A, B, C, D, and E.
Step 2: Understand the conditions: A and B must be completed before C, and C must be completed before D.
Step 3: List the tasks that must come before C: A and B.
Step 4: List the tasks that must come before D: C.
Step 5: Determine a possible order: Start with A and B since they must be done before C.
Step 6: After A and B, place C next in the order since it must come after A and B.
Step 7: After C, place D since it must come after C.
Step 8: Finally, place E at the end since it has no restrictions.
Task Dependency – Understanding the order in which tasks must be completed based on given prerequisites.
