Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The adoption of practices may be relatively higher, when more than five methods of extension techniques were used, as compared to single extension technique.
Reason (R): Single extension technique usually proves to be useless, from adoption's point of view.
In light of the above statements, choose the most appropriate answer from the options given below.

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

Hint:

Using a mix of different extension methods (personal, group, and mass contact) creates a reinforcing effect that is much more effective than relying on any single method alone.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
In their classic studies, Wilson and Gallup demonstrated the cumulative effect of using multiple extension methods.
Exposing farmers to a new practice through several different channels significantly increases the adoption rate.

Step 2: Detailed Explanation:
Let us evaluate both statements:
- Assertion (A):
"The adoption of practices may be relatively higher, when more than five methods of extension techniques were used, as compared to single extension technique."
This is correct.
Wilson and Gallup's research showed that when farmers are exposed to an innovation through five or more different methods (e.g., result demonstration, farm visit, leaflet, radio talk, and group meeting), the adoption rate rises to over 80%-90%.
A single contact method rarely provides enough exposure to persuade a farmer to adopt.
- Reason (R):
"Single extension technique usually proves to be useless, from adoption's point of view."
This is incorrect.
A single extension technique is not "useless".
It still reaches and influences early adopters or highly motivated farmers.
However, it is simply less effective on its own than a combination of multiple complementary methods.
Therefore, Assertion (A) is correct, but Reason (R) is incorrect.

Step 3: Final Answer:
The correct option is (B).
