If it asks about a site, recall its location, river, excavator, and special discovery. If it concerns an artefact, distinguish the place where it was found from the material or interpretation attached to it. Archaeological interpretations may change when new evidence appears, so use the standard association accepted in school texts and competitive examinations. Evidence of field plowing was found at Kalibanga in Rajasthan. A plowed field with furrows running in two directions was discovered, indicating the practice of double-cropping. This is the earliest evidence of plowing in the Indian subcontinent and a top SSC/UPSC fact.
