Questions & Step-by-Step Solutions
Given the constraints that X must be scheduled before Y, and Z must be scheduled after Y, which of the following sequences is correct?
Step 1: Identify the constraints given in the question. We have two constraints: X must be scheduled before Y, and Z must be scheduled after Y.
Step 2: Write down the first constraint: X comes before Y. This means in any correct sequence, X should appear before Y.
Step 3: Write down the second constraint: Z comes after Y. This means in any correct sequence, Y should appear before Z.
Step 4: Combine the two constraints. We need a sequence where X is before Y and Y is before Z.
Step 5: Check the sequence X, Y, Z. In this sequence, X is before Y (satisfying the first constraint) and Y is before Z (satisfying the second constraint).
Step 6: Conclude that the sequence X, Y, Z satisfies both conditions.
Scheduling Constraints – Understanding the order in which tasks or events must occur based on given conditions.
Logical Reasoning – Applying logical deduction to determine the correct sequence based on provided constraints.
