The default sorting column is always the one that makes the least sense. That's just how SQL rolls, baby!

I heard the SQL team was working on a new feature: 'INTERSECT_AND_DANCE' - it sorts the results and then does the Macarena. Revolutionary!

This is a tough one. I was going to go with option A, but now I'm wondering if that's too obvious. Time to review my SQL notes!

I believe it's option E, the first NUMBER or VARCHAR2 column in the last SELECT of the compound query.

Hmm, I'm leaning towards option E. The first numeric or string column in the last SELECT seems like a reasonable default. But I could be wrong.

I'm not sure about this one. I was thinking it might be option B, but now I'm second-guessing myself. Sorting SQL queries can be tricky!

I think option D is the correct answer. The first column in the first SELECT of the compound query should be the default for sorting the output.
