To rewrite the sentence in active voice, the subject performing the action needs to be identified. The sentence in passive voice seems to imply that there were explanations and specifications being provided about inspections and examinations. Therefore, in active voice, the information would directly name the subject that is doing the explaining or specifying.
An example of an active voice version could be:
- "The inspector would explain the sound of an issue, specify the frequency of examinations, explain why inspections are important, and identify who inspected the wheels."
In this active version, it is clear who is performing the actions (the inspector) and what they are doing (explaining, specifying, identifying).
