Final answer:
Understanding the root cause is the best question to investigate a problem when following the problem-solving steps.
Step-by-step explanation:
The best question to help investigate a problem when following the problem-solving steps is Understanding the root cause. This question helps identify the underlying reason or cause of the problem, which is crucial for finding effective solutions. By understanding the root cause, we can address the problem at its source and prevent it from recurring.
For example, if the problem is that a student is consistently late to school, understanding the root cause could involve asking questions like:
- What is causing the student to be late?
- Is it because they have a long commute or poor time management skills?
- Are there external factors like traffic or family responsibilities?
- Are there any barriers preventing them from being punctual?
By asking these questions and understanding the root cause, we can then come up with appropriate solutions to help the student arrive at school on time.
