What should Sanitation Worker Yamata report about the graffiti incident?

Reporting that Mrs. Stanley identified one boy as Randy McGill is crucial because it provides specific information about the incident and identifies one of the individuals involved in the vandalism. This detail is significant for any follow-up investigations or actions that the appropriate authorities might take. Accurate identification of individuals involved in such incidents helps to ensure accountability and may lead to resolution or corrective measures.

The other options, while potentially relevant, don't provide as pertinent information regarding the incident involving graffiti. For example, understanding that two boys were involved or that only one witness was present does not give as direct a link to action as identifying a specific individual. Reporting damage to a truck, while potentially serious, does not pertain directly to the graffiti act itself unless it is connected to the same incident, creating a less focused report. Hence, identifying a suspect is of greater immediate importance in the context of the graffiti event.
