Final answer:
The fifth step in the six-step problem-solving technique is b. Ask Did the solution work?, which is a critical evaluation of the effectiveness of the applied solution.
Step-by-step explanation:
In the six-step problem-solving technique, the fifth step involves evaluating the effectiveness of the chosen solution. The correct answer is b. Ask Did the solution work? This step is crucial as it allows for the assessment of the solution in practice and helps determine if the outcome successfully resolves the problem. By asking this question, an individual can confirm the validity of their solution. After assessing the solution, one might need to return to earlier steps to reconsider the approach or fine-tune the solution.
Being able to determine if an answer is reasonable is an essential skill in problem-solving. It requires analyzing the solution's magnitude, direction, and units to ensure that each aspect aligns with what would be expected based on the problem's parameters. Experience plays a significant role in making these judgments easier and more intuitive over time.
