Answer to Question 1

FALSE

Answer to Question 2

Lifecycle classes are responsible for managing a set of other objects, especially when a large number of entity classes are involved. They create, organize, track, and destroy other objects, often instances of entity classes.
Lifecycle objects help both the management of complexity and reuse. Lifecycle classes have similar missions; therefore, they have similar attributes and operations as well:
- they are collections, responsible for managing multiple objects, from a few to thousands;
- they provide a set of navigational operations such as first, next, previous and last that allow outside entities to browse among objects within the collection;
- they expose individual objects upon request;
- they provide lists of objects in their care; and
- they often provide operations such as search or find to select subsets that satisfy specific criteria.
