after the colony fell into the hands of the English in 1796
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'after the colony fell into the hands of the English in 1796' appears verbatim, with the subject (British Guiana), predicate (fell into hands of), object (English), and time (1796) all explicitly matching.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (not a named source). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's neutral tone. The time is accurately set to 1796 with valid_from matching. The context is appropriately empty as no special sense or role restriction applies. The quote is verbatim from the passage and directly supports the claim.
In 1849 British Guiana exported only 109,600 pounds
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'In 1849 British Guiana exported only 109,600 pounds.' The subject (British Guiana), predicate (exported), object (coffee, implied by context of the entire passage about coffee production), and time (1849) are all explicitly supported by the text.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself presents this information). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's straightforward reporting. The time qualifiers (when, valid_from, valid_to all set to 1849) accurately reflect the temporal scope stated in the passage. Context is empty as the passage does not restrict this to a particular sense. The quote is verbatim from the passage and directly supports the claim.
there was no planting in what is now British Guiana (then a Dutch colony) until 1752
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'there was no planting in what is now British Guiana (then a Dutch colony) until 1752.' This is a direct quote that matches the subject, predicate, object, time, and context of the claim.
- qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage. All major qualifiers are accurate: the viewpoint is correctly identified as 'author', the stance is appropriately 'asserts', sentiment is neutral, the time is correctly set to 1752, and the context appropriately notes the Dutch colonial status. The quote is verbatim and supports the claim. Minor note: the valid_to field is null, which is appropriate since the passage provides no end date for the planting beginning in 1752. The claim accurately represents the passage's factual content about when coffee planting commenced in what became British Guiana.
For a long period thereafter there was little production, and practically no exportation
judge verdicts (2)
- groundedness 0.80 pass — The claim is directly supported by the passage, which explicitly states 'For a long period thereafter there was little production, and practically no exportation' following 1849. The only minor issue is the awkward predicate phrasing 'production little with' instead of a more natural construction, but the core assertion about limited coffee production in British Guiana for an extended period after 1849 is clearly grounded in the text.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. Viewpoint correctly identifies 'author' (the passage is a historical narrative without attribution to a named source), stance correctly uses 'asserts', sentiment is neutral, and the quote appears verbatim and supports the claim. The time qualifiers are appropriate - 'valid_from': 1849 correctly marks the beginning of the period (when exports dropped to 109,600 pounds), and 'valid_to': null appropriately reflects the passage's lack of specified end date for this period. Context is correctly left empty as the passage discusses coffee in its general sense without restricting to a specific sense, role, or period. Minor deduction only for slight imprecision in the predicate phrasing ('production little with' is awkward), though this is a minor issue in representation rather than qualifier fidelity per se.
