In the questions given below, there are two statements marked as Assertion (A) and Reason (R). Read the statements and choose the correct option.  

Assertion (A): ‘Western Disturbances’ disturb the calm and quite weather of North and  North– western India by causing cyclonic rains over the plains and snowfall in the mountains.  

Reason (R): Winter rainfall caused by them locally known as ‘Mahawat’ is of immense importance for the cultivation of Rabi crops. 

Options:  

(a) Both (A) and (R) are true and (R) is the correct explanation of (A).

(b) Both (A) and (R) are true and (R) is not the correct explanation of (A).

(c) (A) is correct but (R) is wrong.

(d) (A) is wrong but (R) is correct.

 

Answer:

Westerly flow brings in the western cyclonic disturbances experienced in the north and north-western parts of the country. They bring much-needed winter rains to the plains and snow to the mountains. The total amount of winter rainfall, known locally as ' Mahawat’ and is suitable for the cultivation of 'rabi' crops.

Therefore,

  • Assertion (A): ‘ Western Disturbances’ disturb the calm and quiet weather of North and  Northwestern India by causing cyclonic rains over the plains and snowfall in the mountains.  This is true.
  • Reason (R) :  Winter rainfall caused by them locally  known as ‘Mahawat’ is of immense importance for the cultivation of Rabi crops.  This is true.
  • Western cyclonic disturbances experienced in the north and north-western parts of the country have no relation with the local name given to the winter rainfall. So, the reasoning is not the correct explanation of the assertion

Thus,

    • Assertion is true .
    • Reasoning is true
    • And, the reasoning is not th e correct explanation of assertion.

So, the correct answer is (b)
