The phrases you provided do not clearly indicate whether they are in passive or active voice, as they seem to describe purposes rather than sentences. However, I can provide insight into the active and passive voice concepts:
- Active Voice: The subject of the sentence performs the action (e.g., "The teacher emphasizes the action").
- Passive Voice: The subject of the sentence receives the action (e.g., "The action is emphasized by the teacher").
If you are asking whether the activities described (emphasizing an action, writing clear concise sentences, or discussing rules or laws) are generally performed in an active or passive manner, it would typically depend on their specific usage in sentences.
If you need clarification or examples of using active or passive voice in such contexts, please let me know!
