I replied wrong - I saw the rollback after the truncate, assumed the question intended to test my understanding that a truncate can be rolled back, and then replied. I had not seen the missing ALL after the UNION operators, nor noticed the duplicate row.
Whew! If I got it wrong for the same reason Hugo did, then I must be doing okay. 😀
