by Q. Consider the following statements:
UPSC Civil Services Examination (Prelims) 2025 – General Studies Paper I
Which one of the following is correct in respect of the above statements?
(a) Both Statement II and Statement III are correct and both of them explain Statement I
(b) Both Statement II and Statement III are correct but only one of them explains Statement I
(c) Only one of the Statements II and III is correct and that explains Statement I
(d) Neither Statement II nor Statement III is correct
Answer: (b) Both Statement II and Statement III are correct but only one of them explains Statement I
Explanation:
Statement I is true – recent studies show that Earth’s rotational axis is shifting, which is linked to mass redistribution (especially from melting glaciers).
Statement II is also scientifically accurate, but it does not directly relate to the shift in Earth’s axis.
Statement III is also correct – melting ice redistributes mass on Earth, contributing to changes in Earth’s rotational axis.
Therefore, only Statement III explains Statement I, although both II and III are correct.
Hence, (b) is the correct answer.
Answer: (b) Both Statement II and Statement III are correct but only one of them explains Statement I
