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.

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 outside knowledge required.
- qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage. All qualifiers are correct: viewpoint is 'author' (passage states this as general knowledge, not attributed to a named source), stance is 'asserts' (presented as fact), sentiment is neutral, time qualifiers are appropriately null (passage gives no temporal scope), and context is empty (appropriate since no specific sense restriction is given). The quote is verbatim and accurately supports the claim about liberica growing best at sea-level to 3,000 feet. Minor deduction (0.1): the quote groups both 'Robusta and liberica' together, so technically the claim extracts only part of the stated grouping, though this is a standard practice for single-subject claims and does not misrepresent the passage's intent.
