1. ... **polite statement** ... (Example: 'The window was broken,' - **is a polite statement**).
**Explanation:**
This section asks to provide passive sentences and then classify the reasons behind the usage of passive form. Here is a breakdown:
* **Unimportant/obvious agent:** When the person or thing doing the action is unknown or not important, we do not need to include it. Ex. The car was stolen.
* **Polite statement:** Passive voice can sound less accusatory or direct. Ex. The report has been misplaced.
* **Emphasis on the agent:** Sometimes, when the doer of the action is important or special, we use passive voice to draw attention to it. Ex. The book was written by Leo Tolstoy.
* **Action more important than the agent:** In news, instructions or processes, we often emphasize the action over who or what performed it. Ex. A new law has been passed by parliament.
* **Process:** If we want to focus on the stages of a process, we may use passive sentences. Ex. The dough is left to rise.
* **News report:** News often uses the passive to be objective and focus on events. Ex. The bank was robbed this morning.
