Let us consider airport check-in and security screening. The airport offers group check-in and individual check-in. Group check-in is only for groups of tourists. The tour guide is responsible for checking in his/her group members. Other passengers including able-bodied passenger, minor (child), and passenger with special needs (e.g. with disabilities) use individual check-in. All the passengers should pass the security screening. In addition, passengers may or may not have luggage. If they have no luggage, they do not have to do baggage check-in.

1. Draw a UML use case diagram that includes all the actors and lists all the major use cases. (40pts)

2) As it is impossible to check in the entire group of tourists at the same time, the group check-in will utilize individual check-in, i.e., check in group members one after another. How do you change your use case diagram to reflect this requirement? (20 pts) 3) For two of the use cases obtained above, please present the details in the format of the following table. Make more tables as you will have more than one use cases. (40 pts)

Use case name
Participating Actors
Flow of events
Entry condition
Exit condition
