In 1918 some 16,000,000 pounds were produced
judge verdicts (2)
- groundedness 0.70 pass — The passage states that in 1918 some 16,000,000 pounds were produced in Dutch Guiana/Surinam. While the claim attributes this production specifically to 'liberica,' the passage discusses liberica in context but the 16,000,000 pound figure appears to refer to total coffee production from the region (which had shifted to liberica cultivation), making the claim a reasonable interpretation with minor rewording from the source text.
- qualifier_fidelity 0.75 pass — The claim is mostly faithful to the passage qualifiers. Viewpoint 'author' is appropriate since the passage presents this as historical fact without attribution to a named source. Stance 'asserts' and sentiment 'positive' are appropriate. Time qualifier correctly specifies 1918. However, the context field is empty when it should specify 'liberica coffee in Surinam/Dutch Guiana' to reflect the passage's restriction of this production figure to liberica specifically grown in that region, not liberica coffee generally. This minor context omission slightly reduces fidelity, but the core claim remains faithful enough to pass the threshold.
At one time--in 1883 and 1884--the annual export was 16,000,000 pounds
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote provided: 'At one time--in 1883 and 1884--the annual export was 16,000,000 pounds.' All elements (subject, predicate, object, and time period) are 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 makes this assertion). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is positive, reflecting the passage's framing of this export volume as demonstrating 'the importance of the industry at the peak of its prosperity.' The time qualifiers (1883 and 1884) match exactly with the passage's temporal markers. The context is appropriately empty as the passage does not restrict this claim to a particular sense or role. The quote is verbatim from the passage and directly supports the claim.
