Here are the appropriate voice recommendations for each reason:
- Emphasize an action - PASSIVE
- Write clear and concise sentences - ACTIVE
- Tell about rules or laws - PASSIVE (though can sometimes be active, passive is more common)
- Explain an action when the subject is unknown - PASSIVE
- Emphasize who is responsible for something - ACTIVE
- To avoid responsibility - PASSIVE
These recommendations reflect typical usage patterns, though context can influence the choice between passive and active voice.
