The largest coffee plantation, owned by the Companhia Agricola de Cazengo
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The largest coffee plantation, owned by the Companhia Agricola de Cazengo, produced in 1913, a record year, nearly 1,500 tons.' The passage explicitly identifies this company as the owner of the largest coffee plantation in Angola.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage states this as fact without attribution to a named source). The stance is 'asserts' which matches the passage's straightforward presentation. The sentiment is neutral, appropriate for a factual statement about land ownership. The time qualifiers are all null, which is correct since the passage provides no specific temporal scope for this ownership claim (the 1913 production figure is about output, not when ownership began). The context 'Angola' is appropriate and matches the passage's geographic framing. The quote is verbatim and supports the claim accurately.

- groundedness 1.00 pass — The claim is directly stated in the passage: 'The largest coffee plantation, owned by the Companhia Agricola de Cazengo, produced in 1913, a record year, nearly 1,500 tons.' All elements—subject, predicate, object, time, and context—are explicitly supported by the text.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as a factual statement, not attributed to a named source). The stance 'asserts' and sentiment 'positive' (implied by 'record year') are appropriate. The time period is accurate (1913 as a record year). The context 'record year' is faithful to the passage's explicit framing. The quote is verbatim and supports the claim. Minor deduction (0.1) for sentiment classification: while 'positive' is reasonable, the passage's framing is more neutral/factual rather than explicitly positive in tone, though 'record year' does carry a slightly positive connotation.
