Which step comes last in the problem-solving approach described?

• A. Evaluate the result
• B. Modify and try again
• C. Generate several options
• D. Implement the plan

Answer: (B)

The key idea is that problem solving here is an iterative cycle. You start by exploring several options, then put a plan into action and see how it performs. After implementing, you assess what happened to determine whether the outcome meets the goal. When the result isn’t quite right or reveals new insights, the next move is to refine the approach—modifying the plan and trying again. This loop—evaluate, then revise and reattempt—keeps improving the solution rather than settling after the first try. The other steps belong earlier in the cycle: generating options and implementing are preparatory, and evaluating comes before refinement.
