  judge verdicts (2)

  • groundedness 1.00 pass — The claim is directly stated in the passage: 'Enslaved Africans brought their knowledge of water control, milling, winnowing, and other agrarian practices to the fields.' The language and content match the source text precisely, with only minor simplification (omitting 'and other agrarian practices').
  • qualifier_fidelity 0.90 pass — The claim is highly faithful to the passage. All qualifiers are appropriate: viewpoint is correctly 'author' (the passage states this as fact, not from a named source); stance is 'asserts' matching the passage's declarative tone; sentiment is neutral, appropriate for factual historical reporting; time is correctly null as the passage provides no specific dates; context 'New World' accurately reflects the passage's geographic restriction; the quote appears verbatim and supports the claim. Minor deduction: the quote includes 'and other agrarian practices' but the claim specifies only 'water control, milling, winnowing' - this is a slight narrowing rather than unfaithfulness, but represents a minor incompleteness in representing the full scope of the quoted knowledge.

  judge verdicts (2)

  • groundedness 1.00 pass — The claim is directly stated in the passage: 'European planters there relied upon the skills of African slaves to cultivate it.' This sentence explicitly asserts the exact relationship described in the knowledge graph claim.
  • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit narrative voice), not a named source. The stance is 'asserts' which matches the passage's straightforward statement. The sentiment is neutral, matching the passage's factual tone. The time qualifiers are all null, which is appropriate since the passage does not provide specific dates for this claim, only contextual placement within 'the colonial era.' The context 'rice cultivation' accurately reflects the passage's scope. The quote appears verbatim in the passage and directly supports the claim.
