Too more tasks for an hour, so we cannot go deep for each task.

This lab should be reviewed. The first question is misleading, as the best answer is "all of the above". If you have a big table, a change in the email address of the customer would need to be reflected in the whole table. If it's an order table, maybe the customer bought a lot of stuff and thus has a lot of lines. We would need to change all those lines. So second answer is good. The third answer is quite valid too. There could be different granularities. Let's say we store "order lines", we could have data related to the "order header". So this would need to be taken into account in the reporting. The correct answer is then "All of the above". + Implicit join on arrays should be considered a bad practice.
