Assertion (A) Analysis

Assertion (A) states that prehistoric archaeology reconstructs the culture of past mankind. This is correct. Prehistoric archaeology specifically deals with human history before the invention of writing systems. Its primary goal is to understand and reconstruct the ways of life, beliefs, and social structures (i.e., culture) of people from these ancient periods using the available material evidence.

Reason (R) Analysis

Reason (R) states that reconstruction is done through artifacts. This is also correct. Artifacts, which are objects made or modified by humans (like tools, pottery, weapons), are the main source of information for prehistoric archaeologists. By studying these artifacts, archaeologists infer details about technology, diet, social organization, and rituals of past populations.

Relationship Between Assertion and Reason

Reason (R) directly explains how Assertion (A) is achieved. The reconstruction of past culture mentioned in (A) is accomplished by analyzing the artifacts discovered, as stated in (R). Therefore, the artifacts serve as the evidence base for the reconstruction process.

Conclusion

Both Assertion (A) and Reason (R) are factually correct statements. Furthermore, Reason (R) provides the correct method and basis for the statement made in Assertion (A). Thus, (R) is a valid explanation of (A).

The most appropriate answer is that both (A) and (R) are correct and (R) is the correct explanation of (A).
