A
I only
B
II only
C
Both I and II
D
Neither I nor II
Correct answer: (a) I only
Explanation
- A
I only
I only. The two towns are a short hop across the Bering Strait but on opposite sides of the International Date Line, so the calendar date can differ.
- B
II only
II only. II has the days backwards: Anadyr (Russia, UTC+12) is ahead of Nome (Alaska, UTC−9). Monday in Anadyr is still Sunday in Nome.
- C
Both I and II
Both. II fails.
- D
Neither I nor II
Neither. I holds.
Summary. Official key is (a) I only. Anadyr and Nome sit either side of the date line, so breakfast can be on different calendar days. When it is Monday in Anadyr it is still Sunday in Nome, not Tuesday — II reverses the order. (c) both.
