Sixteen years later, there were 17,000 trees in Para
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states 'Sixteen years later, there were 17,000 trees in Para' following the 1732 date, which correctly calculates to 1748, and the temporal and numerical information matches exactly.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as historical fact). The stance is appropriately 'asserts' as the passage states this as a definitive claim. The sentiment is neutral, matching the passage's factual tone. The time is correctly normalized to 1748 (1732 + 16 years = 1748), which is consistent with the passage's temporal reference. The context is appropriately empty as no specific sense or role restriction applies. The quote appears verbatim in the passage and accurately supports the claim about the number of coffee trees in Para.
by 1770, an export trade had been begun from the port of Para to countries in Europe
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'by 1770, an export trade had been begun from the port of Para to countries in Europe.' The subject, predicate, object, and timeframe all match the source text precisely without requiring outside knowledge or over-generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (the passage presents this as factual historical narrative without attribution to a named source). The stance 'asserts' matches the passage's straightforward presentation. Sentiment is neutral, consistent with the factual tone. The time qualifier 'by 1770' with valid_from '1770' accurately reflects the passage's temporal scope, and valid_to is correctly null as the passage provides no end date. Context is empty, which is appropriate as the passage does not restrict the claim to a particular sense or role. The quote is verbatim from the passage and directly supports the claim.
The first coffee plantation in Brazil was started at Para in 1723
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The first coffee plantation in Brazil was started at Para in 1723 with plants brought from French Guiana.' All elements (subject, predicate, object, time, and context) are explicitly supported without any rewording or outside knowledge required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (no named source in the passage), the stance is correctly marked as 'asserts', sentiment is neutral as appropriate, the time is accurately specified as 1723 with no end date, the context correctly identifies this as 'first in Brazil', and the quote matches verbatim from the passage and directly supports the claim.
Brazilian soil first made the acquaintance of the coffee plant at Para in 1723
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Brazilian soil first made the acquaintance of the coffee plant at Para in 1723.' All elements (subject, predicate, object, time) are explicitly present and accurately represented.
- qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage. The viewpoint, stance, sentiment, and time qualifiers are all correct - the passage does attribute this to the author/narrator and presents it as a neutral assertion dated 1723. The quote is verbatim and supports the claim. Minor deduction: the context field is empty, but the passage does not restrict the claim to a specific sense (plant vs. drink), so this is appropriate. One small note: the 'valid_to' is correctly null since the passage provides no end date for this arrival event.
The first coffee plantation started in the Portuguese colony of Para, Brazil
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly states 'The first coffee plantation started in the Portuguese colony of Para, Brazil, with plants brought from Cayenne (French Guiana)' under the 1723 entry, matching all key elements of the subject, predicate, object, and time period.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The viewpoint is correctly attributed to the author (not a named source), stance is appropriately 'asserts', sentiment is neutral, time is accurate (1723), and context correctly identifies Para as a Portuguese colony. The quote is verbatim. Minor deduction: the passage explicitly states this plantation 'results in failure,' which is significant contextual information about the outcome that the claim omits, though this is a content completeness issue rather than qualifier infidelity per se. All qualifiers as specified in the claim are faithful to the passage.
