Now I’m a competitive so-and-so at the best (or worst) of times. And as with most journalists, I harbor the (mis)belief that I know, well, pretty much everything about everything. So in lieu of a newsletter note today, I’m instead issuing a challenge: The Conversation has just started running a weekly news quiz to test just how closely people are following our stories and what they’ve learned.

I managed a majestic 7 out of 8 in today’s quiz. Can any of you do better? I doubt it, particularly given how challenging this week is. So go on, prove me wrong. A lovely and rare tote bag from The Conversation will go to the first person who replies to this email with a screenshot proving they got all eight questions right! Don’t forget to include your name so that we can include an honor roll in next Friday’s newsletter.

Take the quiz here:

Also today:

And one final, nontrivial question: What happens to a nonprofit news organization when the public doesn’t support it? I’d rather not find out. So please, support us today.
