Answer to Question 1

Business classes are those that have a counterpart in the real world: tree, student, contract, office, poet, shirt, patient, etc. The discovery of business classes and their relationships is the main task of analysis. Utility classes are those that lack a direct counterpart in the real world and are used to create objects that manage the responsibilities of the information system: to interact with the outside world, to make communication among business objects possible, and to save information when required. Command buttons, menus, and dropdown lists are a few such classes. Discovery and definition of utility classes and their relationships is the task of design.

Answer to Question 2

B

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
