Question 1
5 people (Barbara, Reese, Daisy, Noor, Raj) live on floors 1 to 5. Their professions: Barbara: Pilot, Reese: Musician, Daisy: Librarian, Noor: Professor, Raj: Surgeon.
Based on these clues:
• Noor lives on floor 5
• the Librarian does not live on floor 2
• the Professor and the Surgeon are exactly 2 floors apart
• the Musician lives on floor 1
On which floor does Barbara live?
The unique arrangement (floor: person) is: {1: 'Reese', 2: 'Barbara', 3: 'Raj', 4: 'Daisy', 5: 'Noor'}.
