Posing a question

When you make a move, you may pose a question about the scene in the image or anything that directly relates to it.
Ask questions that genuinely interest you, or that will be challenging and interesting to answer.
"Why" and "how" are often good questions. E.g. "why was this city destroyed?"; "how did this get here?".
Before you ask a question, be sure that you haven't left nothing interesting to say about the image, so people still have space to interpret it. 

By asking those questions, you prohibit anyone from answering them in the comments on this image.
This means you are encouraging others to post images that might help to answer the question. Therefore, pose questions that you want your friends to creatively answer through pictures. 

The game cannot end until at least half the questions posed have been answered.
Avoid posing questions that are so vague that they can never be definitively answered.

The Host should summarise questions posed in a post, updating as the game progresses, so everyone can easily see what questions have been asked so far.
