Write general questions. Don't use question marks (they are given):
1. They've attached a photo of their house.

1. What have they attached?
In this sentence, the verb "attached" is used to describe an action that someone has done. The subject of the sentence is "they," and the object of the action is "a photo." So, the question asks about what "they" have attached.

2. Who have they attached it to?
This question focuses on the target or recipient of the attachment. By asking "who," we inquire about the people or entity to whom the photo is attached. The given sentence doesn't provide this information explicitly, so we need to use our imagination or ask for more context.

3. Why have they attached a photo of their house?
Here, the question delves into the purpose or reason behind attaching the photo. It seeks an explanation for why they took the action of attaching a photo of their house. Again, the given sentence doesn't provide the reason, so we need more context.

4. When did they attach the photo of their house?
This question addresses the time frame during which the attachment action took place. By asking "when," we want to know the specific moment or period when the attachment occurred. To answer this, we need additional information.

5. How did they attach the photo of their house?
This question explores the method or manner used to attach the photo. By asking "how," we want to understand the process or means they employed. The given sentence doesn't provide this information, so we need more context.

Overall, we can see that the given sentence prompts us to think about additional aspects related to the attachment action. By asking these general questions, we dig deeper into the details and seek a more comprehensive understanding of the situation.
