1. Active is better in this instance because it is more clear and concise.
2. Active is better in this instance if the lifeguard is more important than John.
   Passive is better in this instance if John’s rescue is more important than the lifeguard.
3. Active is better in this instance if it is necessary to know who made the mistake.
   Passive is better in this instance if you want to strategically avoid the subject, Sarah.
4. Active voice is better in this instance because it is academic writing, and it is more clear and concise than the passive voice.
