Question 1 - Assertion Reasoning - Chapter 4 Class 10 Geography - Agriculture - Geography

Assertion (A): Agriculture is an old economic activity.

Reason (R): Farming varies from subsistence to commercial type.

Answer: 

Agriculture is an old economic activity. Cultivation techniques change from crop to crop depending upon the characteristics of physical, environmental, and technical methods. 

Therefore, 

• Assertion (A): Agriculture is an old economic activity - Agriculture was started in 9000 BCE . So, this is true
• Reasoning (R): Farming varies from subsistence to commercial type - Cultivation techniques change from crop to crop depending upon the characteristics of physical, environmental, and technical methods . So, this is true.
• But, different farming methods have no relation to agriculture being an old economic activity. So, reasoning is not a correct explanation of assertion

Thus, 

• Assertion is true .
• Reasoning is true
• But reasoning is not a correct explanation of Assertion. 

So, the correct answer is (B)
