Step 1: Understanding the Concept:
This question focuses on how different social systems adopt innovations, drawing on sociological and extension concepts.
It examines how a community's openness to modernity affects how quickly they adopt new ideas or technologies.
Step 2: Detailed Explanation:
Let us analyze the assertion and reason individually:
Assertion (A):
A social system that values modernity is generally open to change, scientific progress, and new ideas.
These values make the community more willing to adopt innovations quickly.
Therefore, a modern social system will have a *higher* rate of innovation acceptance, not a lower one.
Thus, Assertion (A) is incorrect.
Reason (R):
In traditional, non-modern societies, social roles, agricultural practices, and daily life are often governed by long-standing customs.
Introducing a new technology or practice can disrupt these traditional systems, leading to significant social and cultural changes.
In contrast, modern societies are already structured to adapt to rapid, continuous change, making new innovations feel more incremental.
Therefore, adopting an innovation can create a much larger relative impact or change in a traditional society.
Thus, Reason (R) is correct.
Step 3: Final Answer:
Assertion (A) is incorrect, but Reason (R) is correct.
This matches Option (D).
