UPSC Prelim 2025 Paper I
  1. Consider the following statements : I. Anadyr in Siberia and Nome in Alaska are a few kilometers from each other, but when people are waking up and getting set for breakfast in these cities, it would be different days. II. When it is Monday in Anadyr, it is Tuesday in Nome. Which of the statements given above is/are correct?
Verified Answer
A. I only
B. II only
C. Both I and II
D. Neither I nor II

Explanation:

Anadyr, Russia, and Nome, Alaska, USA, are separated by the International Date Line. This means that despite their geographical proximity, they are on different calendar days. Statement I is correct because crossing the International Date Line changes the date. Statement II is incorrect because Anadyr is west of the International Date Line, and Nome is east. If it's Monday in Anadyr (west of IDL), it would be Sunday in Nome (east of IDL), not Tuesday.
