Assertion: Alfred Russel Wallace, a prominent naturalist, conducted extensive research in the Malay Archipelago, encompassing what is now known as modern Indonesia.
Reason: The rationale behind his endeavors was the subdivision of the Earth into seven distinct geographical realms, which he established by analyzing the distribution patterns of invertebrate species.
Both Assertion & Reason are True &the Reason is a correct explanation of the Assertion.
Both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
Assertion is True but the Reason is False.
Both Assertion & Reason are false.
The assertion states that Alfred Russel Wallace conducted extensive research in the Malay Archipelago, which is now modern Indonesia. This is true. Wallace is well-known for his explorations in Southeast Asia, particularly in Indonesia, where he made significant contributions to the field of natural history.
However, the reason given for his endeavors, which is the subdivision of the Earth into seven distinct geographical realms based on the distribution patterns of invertebrate species, is false. While Wallace did study the distribution patterns of species, his concept of dividing the Earth into seven realms was based on biogeographic regions, not solely on invertebrate distribution.
Therefore, the assertion is true and the reason is false, making option 3 the correct answer.
