Consider the following statements:
Statement I:
The amount of dust particles in the atmosphere is more in subtropical and temperate areas than in equatorial and polar regions.
Statement II:
Subtropical and temperate areas have less dry winds.
Which one of the following is correct in respect of the above statements?
(a)
Both Statement I and Statement II are correct and Statement II explains Statement I
(b)
Both Statement I and Statement II are correct but Statement II does not explain Statement I
(c)
Statement I is correct but Statement II is not correct
(d)
Statement I is not correct but Statement II is correct
Explanation
Answer: (c) Statement I is correct but Statement II is not correct
Explanation:
• Statement I: Subtropical and temperate regions (e.g., deserts like the Sahara) have higher dust particle concentrations due to dry conditions and wind activity, compared to humid equatorial or cold polar regions. This is correct.
• Statement II: Subtropical and temperate areas often have more dry winds (e.g., in deserts), which increase dust levels, not less. This is incorrect.
• Explanation Check: Since Statement II is incorrect, it cannot explain Statement I. Thus, (c) is the answer.
