Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Famine and drought are common in western dry region.
Reason (R): The area has erratic rainfall with highly evaporation and absence of perennial rivers. Choose the correct answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is incorrect
• D. (A) is not correct but (R) is correct

Hint:

Western dry regions =
• Low rainfall
• High evaporation
• No perennial rivers These directly lead to drought and famine.

Answer 1

The Correct Option is A

Concept:
Assertion-Reason questions test both factual knowledge and logical relationship. Western dry regions (like Rajasthan) are characterized by climatic extremes affecting agriculture and water availability.

Step 1: Understanding Assertion (A)

• Western dry regions frequently face drought conditions.
• Lack of sufficient rainfall leads to famine situations. Thus, Assertion (A) is correct.

Step 2: Understanding Reason (R)

• Rainfall is highly irregular and insufficient.
• High temperature leads to high evaporation rate.
• Lack of perennial rivers reduces water availability. Thus, Reason (R) is correct.

Step 3: Logical relationship between (A) and (R)

• Erratic rainfall + high evaporation + lack of rivers
• $\Rightarrow$ Water scarcity
• $\Rightarrow$ Drought conditions
• $\Rightarrow$ Famine Thus, Reason (R) correctly explains Assertion (A). Final Conclusion: \[ \boxed{\text{Both (A) and (R) are correct and (R) explains (A)}} \]
