To solve the problem, we will analyze the clues systematically and deduce the occupations of Brianna, Jessie, Mario, and Jack.
From Clue A, we know the sequence of Brianna's arrival:
From Clue B, Jessie is the last to leave work and cannot be the editor. Thus, the only possible occupations for Jessie are Chef or Dentist.
Now, using Clue C, since the dentist leaves at the same time as Jessie, Jessie cannot be the dentist, which means:
With Jessie as the Chef, the remaining occupations are Editor, Dentist, and Banker. From Clue A, since Brianna came home after the banker, it confirms that Brianna cannot be the banker. Hence, we can deduce that:
From Clue D, the Banker lives next door to Jack. Since Brianna is the Editor and Jessie is the Chef, one of the remaining two (Mario or Jack) must be the Banker. Therefore, the other one must be the Dentist.
Now, we can summarize what we have:
To determine who between Mario and Jack is the Banker and who is the Dentist, we focus on the information left considering Clue C states that Jesse leaves for work at the same time as the Dentist, meaning that Jack cannot be the Dentist because he would not be "next door" to the Banker. Therefore, Mario must be the Dentist and Jack the Banker.
Now we have:
This analysis confirms that we have deduced the correct occupations based on the clues provided. Each friend's occupation is now clear.
