while many devices have been tried, not one has proved successful
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the final sentence of the passage: 'while many devices have been tried, not one has proved successful.' This explicitly states that devices/machines for cutting cane by machinery have proven unsuccessful.
- qualifier_fidelity 0.95 pass — Quote should read "not one has proved successful" to be fully verbatim. The claim states "has proved unsuccessful for" which captures the meaning but inverts the grammar slightly. All qualifiers are otherwise faithful: viewpoint (author), stance (asserts), sentiment (negative), time (null as passage gives no temporal scope), and context ("many devices have been tried") are all accurate and well-supported by the passage. Minor deduction for quote wording variation.
