All elements (subject, predicate, object, time, and context) are explicitly supported without any rewording or outside knowledge required.

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.
but it was not a success
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, but it was not a success.' The exact phrase 'was not a success' appears verbatim in the source text.
- qualifier_fidelity 0.90 pass — Nearly all qualifiers are faithful. The passage directly states 'The first coffee plantation in Brazil was started at Para in 1723 with plants brought from French Guiana, but it was not a success.' The quote is verbatim and supports the claim. Viewpoint, stance, sentiment, time (1723), and context (Para 1723) all match the passage. Minor deduction only because 'valid_from' and 'valid_to' are technical qualifier fields not explicitly addressed by the passage's temporal scope, though the when field is correct.
Plantations having from 300,000 to 400,000 trees are common
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'Plantations having from 300,000 to 400,000 trees are common,' confirming that coffee plantations typically contain coffee trees in these quantities.
- 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 factual observation without attributing it to a named source). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the informational tone. The time qualifiers are correctly null since the passage provides no specific temporal scope for this general statement about typical plantation sizes. The context is appropriately empty as the passage does not restrict the claim to a particular sense or role. The quote appears verbatim in the passage and directly supports the claim that typical plantations contain 300,000-400,000 trees.
There are fifteen plantations having more than 1,000,000 trees each
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'There are fifteen plantations having more than 1,000,000 trees each.' The subject-predicate-object relationship (coffee plantations have coffee trees) is explicitly supported by this sentence.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author/passage itself rather than a named source. The stance is appropriately 'asserts' as the passage presents this as factual information. The sentiment is neutral, matching the objective tone of the passage. The time qualifiers are correctly null since the passage provides no specific temporal reference for this particular claim (unlike the 1922 date mentioned for Ribeirao Preto municipality). The context accurately reflects the specific subset of plantations described. The quote appears verbatim in the passage and directly supports the claim about fifteen plantations having more than 1,000,000 trees each.
five of these have more than 2,000,000 trees each
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'five of these have more than 2,000,000 trees each' explicitly confirms that five coffee plantations have more than 2,000,000 coffee trees each. This is fully supported 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 the author (the passage presents factual statements without attribution to named sources). The stance is appropriately marked as 'asserts' since the passage states this as fact. The sentiment is neutral, matching the objective, informational tone of the passage. The time qualifier is correctly set to null since the passage provides no specific date for this particular statement about the five plantations. The context accurately specifies the subset being discussed ('five plantations with more than 2,000,000 trees'). The quote is verbatim from the passage and directly supports the claim about these plantations having coffee trees.
Another planter owns thirty-two adjacent plantations
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Another planter owns thirty-two adjacent plantations containing, in all, from 7,500,000 to 8,000,000 coffee trees.' The subject, predicate, and object are explicitly mentioned 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 the author (the passage presents this as factual information without attribution to a named source). The stance is 'asserts' which matches the declarative presentation. The sentiment is neutral, appropriate for the descriptive nature of the statement. The time qualifiers are all null, which is correct since the passage provides no specific date for this claim (the 1922 date mentioned applies only to the municipality of Ribeirao Preto's tree count, not to this planter). The context is empty, which is appropriate. The quote 'Another planter owns thirty-two adjacent plantations' appears verbatim in the passage and accurately supports the claim.
