Question

Match the following extension concepts with their most suitable explanation:
\begin{tabular{ll} List-I (Extension concept) & List-II (Suitable explanation)
(A) Campaign & (I) PRA/ RRA
(B) Expert system & (II) Effective interpersonal relation and social transaction
(C) Transact walk & (III) Computer programme
(D) Role playing & (IV) Social & political change

Choose the correct answer from the options given below:

• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (IV), (B) - (III), (C) - (I), (D) - (II)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (I), (C) - (II), (D) - (IV)

Hint:

An expert system is always a computer programme (B - III).
A transect walk is a standard, hands-on tool of Participatory Rural Appraisal (C - I).
These two relationships make it simple to find the correct option.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Agricultural extension employs various methodologies, tools, and educational strategies to transfer technology and bring about planned change in farming communities.

Step 2: Detailed Explanation:
Let us correlate each extension concept in List-I with its correct description in List-II:
- (A) Campaign: An intensive, educational, and highly organized communication effort aimed at generating mass awareness and driving social, behavioral, or political change in a community.
Thus, (A) matches with (IV).
- (B) Expert system: In agricultural information technology, an expert system is a specialized computer program that emulates the decision-making ability of a human expert to solve complex agricultural problems.
Thus, (B) matches with (III).
- (C) Transect walk: This is a systematic, structured walk through a local area along a defined path, which is a core tool in Participatory Rural Appraisal (PRA) and Rapid Rural Appraisal (RRA) used to observe spatial variations and resources.
Thus, (C) matches with (I).
- (D) Role playing: An educational method where participants act out real-life scenarios, helping to develop effective interpersonal relationships, empathy, and social transaction skills.
Thus, (D) matches with (II).
This results in the matching sequence: (A)-(IV), (B)-(III), (C)-(I), (D)-(II).

Step 3: Final Answer:
The correct matched sequence is represented by option 2.
