Concept:
The Chalcolithic Age is also called the Copper-Stone Age because people used both:
• stone tools,
• and copper implements.
This period represents an important transitional phase between the Neolithic Age and the Iron Age.
Step 1: Understanding Assertion (A).
Assertion (A) states:
\[
\text{The Chalcolithic culture had an essentially rural background.}
\]
This statement is correct.
Most Chalcolithic settlements:
• were village-based,
• depended on agriculture,
• practiced animal domestication,
• and lacked large urban centers.
Therefore, the culture had a predominantly rural character.
Step 2: Understanding Reason (R).
Reason (R) states:
\[
\text{Many Chalcolithic cultures were younger than the Indus Valley Civilization and adopted advanced technologies.}
\]
This statement is also broadly correct.
Several Chalcolithic cultures:
• developed after the mature Harappan phase,
• interacted with post-Harappan traditions,
• and adopted certain technological practices.
Step 3: Evaluating the relationship between Assertion and Reason.
Although both statements are correct, the Reason does not explain why Chalcolithic culture had a rural background.
The rural nature mainly resulted from:
• agricultural village economy,
• small settlements,
• and limited urbanization.
Thus:
• Assertion (A) is correct,
• Reason (R) is correct,
• but Reason (R) is not the correct explanation of Assertion (A).
Step 4: Historical significance of the Chalcolithic Age.
The Chalcolithic period is important because:
• agriculture expanded,
• pottery improved,
• copper tools appeared,
• and village settlements became more organized.
It marks a major stage in prehistoric development.
Step 5: Final conclusion.
Both Assertion and Reason are correct, but the Reason does not correctly explain the Assertion.
Therefore, the correct answer is:
\[
\boxed{\text{Both (A) and (R) are correct but (R) is not the correct explanation of (A)}}
\]
