Sorry, jordan - if you read the first post on this thread by norah (admin) you'll see that we're being discouraged from giving the kind of answer you're asking for.
I hope this helps you arrive at the correct choice -
The preamble states that if we ''fill the bottom row'' with a surname we'll be revealing ''answers to the title's questions'', so the answers only appear when the name is inserted (and there has already been a mention of them being 'terse' answers). Then it's just a matter of reading the wiki synopsis to see what conditions prevail for each of the choices (what if this happens? What if that...?).
