Answer to Question 1

TRUE

Answer to Question 2

Candidate keys occur when an entity has more than one unique attribute. In such cases, each unique attribute is also called a candidate key. The term candidate key comes from the fact that a candidate key is a candidate to be chosen as the primary identifier (also known as a primary key) when implementing the resulting database.
