I encourage you to read that thread and see if you can contribute to the idea it is promoting, but not until you’ve had a guess here! Readers of that thread and the people appearing in the photo should recuse themselves. Over to you!

Edit: lots of right answers (which I’ve now unhidden). Well done, Owen!
