Answer to Question 1

A

Answer to Question 2

In queries where the inner query (nested query) uses columns from the relations listed in the SELECT part of the outer query, the inner query is referred to as a correlated subquery. In such cases, the EXISTS operator can be used to check if the result of the inner correlated query is empty.
