Question

Match List-I with List-II

List-I (Scientist)		List-II (Concept)
A	Rogers and Shoemaker	I	Intelligence
B	Daniel Benor	II	Communication
C	Edgar Dale	III	Training and Visit
D	Wechsler	IV	Cone of Experience

Choose the correct answer from the options given below:

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

Hint:

To solve extension-matching questions quickly, associate Daniel Benor with the "Training and Visit" (T&V) system and Edgar Dale with the "Cone of Experience." These are classic, highly tested associations in agricultural extension.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Agricultural extension, communication, and education rely on key psychological, communication, and management theories developed by prominent researchers.
These theories help extension workers design training programs and communicate effectively with farmers.

Step 2: Detailed Explanation:
Let us match each researcher with their corresponding concept:
- (A) Rogers and Shoemaker: In 1971, Everett Rogers and F. Floyd Shoemaker published "Communication of Innovations," which analyzed how ideas, technologies, and practices spread through social systems. Thus, (A) matches with (II).
- (B) Daniel Benor: An Israeli agricultural expert who designed the "Training and Visit" (T&V) system of extension in the 1970s.
Adopted widely by the World Bank, the T&V system structured extension work through regular training of field staff and scheduled visits to farmers. Thus, (B) matches with (III).
- (C) Edgar Dale: An American educator who developed the "Cone of Experience" in 19
This visual model organizes learning experiences based on their level of concreteness, ranging from direct, purposeful experiences at the base to abstract verbal symbols at the apex. Thus, (C) matches with (IV).
- (D) Wechsler: David Wechsler developed the Wechsler Intelligence Scales (such as the WAIS and WISC), which are widely used standardized tests designed to measure human intelligence. Thus, (D) matches with (I).
Combining these pairs, we get: (A) - (II), (B) - (III), (C) - (IV), (D) - (I).

Step 4: Final Answer:
The correct matching sequence is (A) - (II), (B) - (III), (C) - (IV), (D) - (I), which corresponds to Option (C).
