in the next thirty years they declined, until they were only 1,147,000 pounds in 1900
judge verdicts (4)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote 'in the next thirty years they declined, until they were only 1,147,000 pounds in 1900' appears verbatim, confirming that Ceylon coffee exports declined to 1,147,000 pounds by 1900, thirty years after the 1870 peak.
- qualifier_fidelity 0.60 fail — The time qualifier is unfaithful. The passage states 'in the next thirty years they declined, until they were only 1,147,000 pounds in 1900' - this means the decline occurred over the thirty years AFTER 1870, concluding in 1900 (1870-1900). However, the claim's 'when' field says 'thirty years later' which is ambiguous and misleading; the 'valid_from' should be 1870 and 'valid_to' should be 1900, but 'when' should be normalized to reflect the specific period (1870-1900) rather than the vague phrase 'thirty years later'. The quote is accurate and the viewpoint/stance/sentiment are correct, but the temporal framing in the 'when' field does not clearly match the passage's explicit date range.
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact quote 'in the next thirty years they declined, until they were only 1,147,000 pounds in 1900' appears verbatim, and the time period (1870-1900) and export figure are explicitly stated.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself makes this assertion). The stance is correctly marked as 'asserts' - the passage straightforwardly states the decline. The sentiment 'negative' appropriately matches the connotation of declining exports. The time period '1870-1900' is accurate: the passage states 'in the next thirty years they declined' following the 1870 high point, reaching 1,147,000 pounds 'in 1900'. The quote appears verbatim in the passage and directly supports the claim. The empty context is appropriate as the passage does not restrict the meaning to a particular sense or role beyond coffee exports generally.
