Case context: A three-stage wildfire warning system turns sensor readings into risk labels and then into a public safety bulletin. Reviewers confirm that the risk labels are correct, but the bulletin sent to residents is inaccurate.

Question: Based only on the responsibilities of each stage, which component should be examined first, and why?

Sample answer: The bulletin generator should be examined first. The risk labels are already correct, so the remaining stage responsible for converting those labels into the public bulletin is the most likely source of the error.

Key points:

• The risk labels are correct.
• The bulletin generator receives the labels.
• It is responsible for producing the final bulletin.
• The observed mistake appears after the labeling stage.

Rubric: The response should identify the bulletin generator, connect it to final output creation, and explain that the correct intermediate labels shift attention to the later stage.
