Robusta and liberica varieties of coffee do best in regions from sea-level up to 3,000 feet
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Robusta and liberica varieties of coffee do best in regions from sea-level up to 3,000 feet.' The subject, predicate, and object are all explicitly supported by the quoted text without any rewording or inference required.
- 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 a general fact, not attributed to a named source). The stance 'asserts' matches the declarative framing. The sentiment is neutral, appropriate for a factual agricultural statement. The time qualifiers are correctly null since the passage provides no temporal scope. The context is appropriately empty as the passage discusses robusta in its standard agricultural sense without restricting to a particular role or period. The quote is verbatim and directly supports the claim about robusta's optimal altitude range.
The _robusta_ tree grows satisfactorily even at altitudes of less than 1,000 feet in some regions
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the passage verbatim: 'The _robusta_ tree grows satisfactorily even at altitudes of less than 1,000 feet in some regions.'

its bearing life is only about ten years
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The _robusta_ tree grows satisfactorily even at altitudes of less than 1,000 feet in some regions; but its bearing life is only about ten years, as compared with the thirty years of the _arabica_ at altitudes of from 3,000 to 4,000 feet.' The exact quote provided matches the passage.
- 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 without attribution to a named source). The stance is appropriately 'asserts' as the passage states this as factual information. Sentiment is neutral, matching the passage's objective tone. The time qualifiers are correctly set to null since the passage provides no temporal scope. Context is empty, which is appropriate as the passage does not restrict this claim to a specific sense or period. The quote appears verbatim in the passage and directly supports the claim.
The east coast has recently gone in for heavy plantings of _robusta_
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The east coast has recently gone in for heavy plantings of _robusta_.' The subject, predicate, object, and temporal qualifier all match the exact wording provided.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself makes the assertion). The stance is accurately 'asserts' as the passage states it as fact. The sentiment is neutral, matching the passage's neutral tone. The temporal qualifier 'recently' matches the passage's use of 'recently'. The context 'Sumatra' is appropriate and accurately narrows the scope. The quote is verbatim from the passage and directly supports the claim. No unfaithful qualifiers identified.
The _robusta_ variety has also been introduced, but does not seem to do as well as the _liberica_
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the text, which explicitly states that robusta has been introduced but does not perform as well as liberica in the Malay context.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit assertion in the text). The stance is 'asserts' which matches the straightforward statement in the passage. The sentiment is negative regarding robusta's performance relative to liberica, which aligns with 'does not seem to do as well as.' The time qualifiers are all null, which is correct since the passage provides no temporal specification for this statement. The context is empty, which is appropriate as the passage does not restrict this claim to a particular sense or role. The quote is verbatim and directly supports the claim.
- robusta were imported in increasing quantities during World War latter years of the World War ⟨latter years⟩
in the latter years of the World War increasing quantities of _robusta_ and _liberica_ growths were imported
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'in the latter years of the World War increasing quantities of _robusta_ and _liberica_ growths were imported.' The subject, predicate, and object all match the passage without requiring outside knowledge or over-generalization.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim and supports the claim. The viewpoint (author), stance (asserts), sentiment (neutral), and time qualifier (latter years of the World War) all accurately reflect the passage. The context qualifier "latter years" is appropriate. One minor note: the 'valid_from' and 'valid_to' fields are set to null, which is correct since the passage does not provide specific normalized dates, only the temporal phrase "latter years of the World War". The claim accurately captures what the passage states about robusta imports during this period.
the improvement in the preparation methods, especially in the case of _robustas_
judge verdicts (2)
- groundedness 0.70 pass — The passage states that robusta growths were imported 'largely because of the scarcity of Brazilian stocks and the improvement in the preparation methods, especially in the case of robustas.' The claim accurately captures this statement, though it slightly rewords 'improvement in the preparation methods' as 'had improvement in preparation methods,' which is a minor rewording variation.
- qualifier_fidelity 0.80 pass — The claim is mostly faithful to the passage. The quote is accurate and verbatim. However, the viewpoint should be "passage" or the actual source rather than "author" - the passage itself presents this as factual information without attributing it to a named source, so "author" is acceptable but imprecise. The stance "asserts" and sentiment "positive" both align with how the passage frames the improvement. The time qualifiers are correctly set to null since the passage provides no specific temporal scope for when this improvement occurred. The context is appropriately empty. The only minor issue is terminology precision around "viewpoint": when the passage itself makes an unattributed claim, "author" is reasonable, though "passage" would be more precise.
The tree, as a whole, is a very hardy variety
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote 'The tree, as a whole, is a very hardy variety' appears verbatim when describing Coffea robusta, making this a fully supported claim with no rewording needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage makes this statement as a general description without attribution to a named source). The stance is properly marked as 'asserts' since the passage presents this as a factual statement. The sentiment is positive, matching the connotation of 'very hardy variety.' The time qualifiers are appropriately null since the passage provides no temporal restriction on this characteristic. The context is empty as appropriate, since the passage does not restrict this claim to a specific sense or role. The quote is verbatim and directly supports the claim.
whose produce is said to possess a better flavor than _robusta_
judge verdicts (2)

- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage.

The time qualifiers are correctly null as the passage provides no temporal restriction. The context is appropriately empty as no specific sense or period restriction applies. The quote matches verbatim and supports the claim.
