The correct option is "I only" because Anadyr, Russia, and Nome, Alaska, are separated by the International Date Line, which results in a time difference that can cause the two locations to experience different days despite their geographic proximity. While it is not accurate to state that "when it is Monday in Anadyr, it is Tuesday in Nome," since both locations would experience the same time of day when adjusted for their specific time zones, the first statement correctly captures the impact of the date line on daily timekeeping. This concept is essential for understanding global time zones and the International Date Line's role in defining date transitions across regions, a topic relevant for UPSC aspirants in the context of geography and geopolitics.
