Very good question overall.Only (minor) issue - picking 6 out of 17 answer options is a task that appears daunting at first sight. The answer options were luckily well organized so that it soon becamse apparent that these were actually six different (but related) multiple choice questions. But it might have been better to create two or three seperate questions, each covering a subset of the answers.
Also: only 9% correct answers so far. With so many things to get right, I'd expect a high failure rate - but not this high!
I was expecting a pretty high failure rate (perhaps not quite as high as it has been so far), because there are a lot of myths about table variables; the myths about them being held in main store, not on disc, or not being held in tempd, and various associated rullbis have been addressed by questions from other question authors, and I thought it would be a good idea to address most of the myths about what constraints they have. Maybe it would have been better split into smaller questions, or maybe it's good to have it all in one place - I didn't actually flip a coin, but I did dither briefly before deciding to put everything in one place.
