The question asks what people assumed about the origin of urban life in India before the Keeladi excavations changed the picture. Let's check each claim against what the passage says archaeologists believed.
Both option A (north urbanised earlier) and option B (IVC as the first urban civilisation) reflect exactly what archaeologists assumed before Keeladi, so the combined option is the accurate one.
Therefore, the correct answer is Option D.
The question asks which option best elaborates on the idea that Keeladi challenges "a single fountainhead of Indian life." Let's test each option against the meaning of that phrase.
Option C is the only one that correctly unpacks what "challenging a single fountainhead" means: it opens up the possibility of multiple, independent origins of Indian civilisation rather than one central source.
Therefore, the correct answer is Option C.
The question asks which conclusion is most convincing given that a script similar to Brahmi (Tamili) has been dated to the sixth century BCE at Keeladi. Let's check each option against that finding.
Only option C stays proportionate to what the evidence actually shows: an earlier, independent development of script and literacy that could meaningfully shift the accepted history of early Indian urbanisation.
Therefore, the correct answer is Option C.
The question asks what the acronym "BCE" stands for. This is a direct factual question, so let's check each option against the standard meaning of the term.
Only option A correctly identifies the standard historical usage: BCE stands for Before the Common Era.
Therefore, the correct answer is Option A.
The question asks what is implied by the detail that a farmer could write his own name on a pot he owned, and by his statement "I have learnt it myself." Let's weigh each option against this detail.
Only option B follows directly from the evidence: a farmer being able to write his own name shows that literacy and education reached beyond the elite in Keeladi society.
Therefore, the correct answer is Option B.
