Answer 1

So

If we look at the table, we can clearly notice that the set of servers who served fewer than 20 customers at lunch is given by Maya and Trey.

If we look at the table again, we notice that the set of servers who served between 20 and 45 customers at dinner is given by Trey, Maya, Lucy and Chau.
