View fourth answer and tell me your opinion

[font="Arial Black"]ALL [/font]the answers are incorrect because there is no column that enforces the order of the data in the original data. Adding a ROWID won't help to do it right. If either in incrementing number or a transaction date/time is not available in the original data, all answers will continue to be incorrect. 😉
