Identify and write definitions for any additional entity, boundary, and control objects participating in the AnnounceTournament use case that were introduced by realizing the change specified in Exercise.

Exercise:

Consider the addition of a nonfunctional requirement stipulating that the effort needed by Advertisers to obtain exclusive sponsorships should be minimized. Change the AnnounceTournament (Figure 1) and the ManageAdvertisements use case (solution of Figure 2) so that the Advertiser can specify preferences in her profile so that exclusive sponsorships can be decided automatically by the system.

Figure 2 Example of use of extend relationship (UML use case diagram). ConnectionDown extends the ReportEmergency use case. The ReportEmergency use case becomes shorter and solely focused on emergency reporting.
