each individual man, woman, and child having more than 12 pounds a year
judge verdicts (2)
- groundedness 0.90 pass — The claim is directly supported by the passage, which explicitly states 'each individual man, woman, and child having more than 12 pounds a year.' The slight deduction from perfect score reflects the passage saying 'more than 12 pounds' rather than exactly '12 pounds,' but this is a very minor discrepancy in precision rather than a substantive error.
- qualifier_fidelity 0.95 pass — The claim is faithful to the passage across all qualifiers. Viewpoint correctly identified as "author" - the passage presents this as the author's own observation, not attributed to a named source. Stance correctly marked as "asserts" - the passage states this as fact. Sentiment is appropriately neutral. Time qualifier "today" is faithful to the passage's temporal reference ("Today it stands at..."). Context correctly specifies "United States, today" matching the passage's scope. The quote is verbatim and supports the claim. Minor note: the passage says "more than 12 pounds" while the claim states "12 pounds" - this is a negligible simplification of the exact phrasing but technically slightly less precise than the passage's qualified language.
- per capita coffee consumption is four times consumption a hundred years ago today versus a hundred years ago ⟨United States⟩
This is four times as much as it was a hundred years ago
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly states 'This is four times as much as it was a hundred years ago' when referring to per capita coffee consumption in the United States, making this a perfect match to the source material.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage does not cite a named source for this statement). The stance is appropriately 'asserts' as the passage states this as fact. Sentiment is neutral, matching the passage's objective tone. The time qualifiers correctly capture the comparison between 'today' and 'a hundred years ago' with no specific dates needed. The context appropriately specifies 'United States' as the passage explicitly discusses U.S. consumption. The quote is verbatim from the passage and directly supports the claim.
- per capita coffee consumption is more than twice consumption in years immediately following the Civil War today versus years immediately following the Civil War ⟨United States⟩
more than twice as much as it was in the years immediately following the Civil War
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'This is four times as much as it was a hundred years ago; and more than twice as much as it was in the years immediately following the Civil War.' The passage explicitly asserts that today's per capita coffee consumption is more than twice the consumption in the years immediately following the Civil War.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implied from the text's own analysis rather than a named source). The stance is appropriately 'asserts' as the passage presents this as fact. The sentiment is neutral, matching the passage's objective tone. The time qualifier correctly captures the comparison between 'today' and 'years immediately following the Civil War' with valid_from and valid_to correctly set to null. The context is accurately specified as 'United States'. The quote is verbatim from the passage and directly supports the claim about per capita consumption being more than twice what it was after the Civil War.
- per capita coffee consumption is fifty percent more than average consumption in twenty years preceding 1897 today versus twenty years preceding 1897 ⟨United States⟩
In general it is fifty percent more than the average in the twenty years preceding 1897
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'In general it is fifty percent more than the average in the twenty years preceding 1897' is the exact quote provided, making this a fully grounded assertion with no rewording needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The quote is verbatim and directly supports the claim. The viewpoint is correctly identified as 'author' (the passage's own assertion). The stance 'asserts' is appropriate for a factual statement without dispute. The sentiment 'neutral' matches the objective, statistical tone. The time qualifier accurately reflects the temporal comparison made in the passage ('today' versus 'twenty years preceding 1897'). The context 'United States' is correct and consistent with the passage's focus on American coffee consumption. All qualifiers are present and accurate.
in which year a new high level of coffee consumption was apparently established
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'in which year a new high level of coffee consumption was apparently established, the per capita figure for that year being 10.12 pounds, which has been approximately the average since then.' The claim accurately captures the passage's assertion about 1897 marking a new high level of per capita coffee consumption in the United States.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage qualifiers. The viewpoint is correctly attributed to the author (the passage does not name a specific source for this observation). The stance 'asserts' is appropriate as the passage presents this as an observation. The sentiment is neutral, matching the factual tone. The time '1897' is correct and matches the passage's statement 'in which year a new high level of coffee consumption was apparently established.' The context 'United States' is accurate. The quote is verbatim and supports the claim. Minor deduction: The claim uses 'apparently established' in implicit form rather than capturing the qualifier word 'apparently' explicitly in the claim structure, though this is a minor presentation issue rather than a factual error. Overall, the qualifiers are faithful to the passage.
- per capita coffee consumption increased by about two pounds per person since prohibition since July 1, 1919 ⟨United States⟩
Since the advent of country-wide prohibition in the United States on July 1, 1919, about two pounds more coffee per person, or 80 to 100 cups, have been consumed than before
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the text verbatim, confirming that per capita coffee consumption increased by about two pounds per person since prohibition on July 1, 1919.
- qualifier_fidelity 0.80 pass — The claim is largely faithful to the passage. The quote is verbatim and accurate, the time period (since July 1, 1919) matches exactly, the context (United States) is correct, and the viewpoint/stance/sentiment are appropriately neutral. However, the predicate 'increased by about two pounds per person since' is slightly imprecise: the passage states this increase occurred 'since the advent of country-wide prohibition' but explicitly notes 'it is yet too early to judge fairly as to the exact effect of prohibition on coffee drinking,' suggesting causation is uncertain. The claim frames this as a direct increase 'since prohibition' which implies a causal relationship, whereas the passage more carefully attributes only a temporal correlation. The predicate should reflect this uncertainty more faithfully.
- per capita coffee consumption is still somewhat low consumption levels after the war ⟨judged by import figures⟩
the per capita consumption, judged by these figures is still somewhat low
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with a direct quote. The passage explicitly states 'the per capita consumption, judged by these figures is still somewhat low' in the context of the post-war period, which aligns with the claim's time frame and context.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implied narrator), the stance is accurately 'asserts' as the passage presents this as factual observation, sentiment is neutral as befits the analytical tone, the temporal reference 'after the war' with valid_from 1918 is appropriate given the post-WWI context, context correctly specifies 'judged by import figures' reflecting the passage's methodological qualifier, and the quote appears verbatim and directly supports the claim.
the big step upward in 1897, when the per capita rose two pounds over the year before
judge verdicts (2)
- groundedness 0.90 pass — The passage directly states that in 1897 there was 'the big step upward' and 'the per capita rose two pounds over the year before.' The claim's phrasing 'rose sharply' is a minor rewording of 'big step upward,' accurately capturing the meaning without adding outside knowledge.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (the passage itself makes the assertion), the stance is 'asserts' (a straightforward factual claim), sentiment is neutral (objective reporting of data), the time is correctly set to 1897, and the context appropriately specifies 'continental United States' as stated in the passage. The quote is verbatim and directly supports the claim about the sharp rise in per capita coffee consumption.
- per capita coffee consumption maintained average established in 1897 since 1897 ⟨continental United States⟩
has been pretty well maintained since
judge verdicts (2)
- groundedness 0.85 pass — The claim is directly supported by the passage, which states that in 1897 per capita rose and 'established an average that has been pretty well maintained since.' The quoted language matches the passage exactly, confirming that this average has been sustained following 1897 in the continental United States context.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage qualifiers. The viewpoint is correctly identified as 'author' since the passage presents this as narrative analysis rather than attributing it to a named source. The stance 'asserts' and sentiment 'neutral' are appropriate. The time qualifier with 'since 1897' and valid_from '1897' accurately reflects the passage's temporal framing. The context 'continental United States' is faithful to the passage's specification. The quote 'has been pretty well maintained since' appears verbatim and supports the claim. Minor deduction: the quote is slightly incomplete as it should read 'has been pretty well maintained since' in fuller context ('established an average that has been pretty well maintained since'), but the extracted portion is accurate enough and supports the predicate appropriately.
when there was a three-pound jump over the year before
judge verdicts (2)
- groundedness 0.70 pass — The claim is supported by the passage, which explicitly states 'Something of the sort may have taken place again in 1920, when there was a three-pound jump over the year before.' The predicate 'rose' accurately captures this meaning, though the original uses 'jump' instead of 'rose.' The temporal specificity and context are correctly identified.
- qualifier_fidelity 0.95 pass — The claim is faithful to the passage across all qualifiers. The viewpoint correctly attributes the observation to the author (implied in the passage's narrative voice), the stance properly reflects the author's assertion, and the sentiment is neutral as the passage reports the fact objectively. The time qualifier accurately captures 1920 as the year of the rise. The context correctly specifies continental United States, which matches the passage's explicit clarification about government per capita coffee figures. The quote is verbatim from the passage and directly supports the claim about the three-pound jump. Minor note: the time object references '1920' while the claim subject 'per capita coffee consumption' could be more precisely characterized as rising 'in 1920' rather than 'to 1920', but this is a semantic distinction that does not affect the overall fidelity of the claim's qualifiers.
for many years before the war she led the world in per capita consumption
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'for many years before the war she led the world in per capita consumption.' The passage explicitly asserts that the Netherlands led the world in per capita coffee consumption during the years before World War I, which aligns perfectly with the claim's subject, predicate, object, and temporal specification.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint is correctly attributed to the author (not a named source), stance is 'asserts' which matches the passage's straightforward claim, and sentiment is positive as befits the statement. The time qualifier 'for many years before the war' with valid_to '1914' is appropriate and consistent with the passage's temporal language. The quote is verbatim and accurate. Minor note: the context is empty, which is acceptable since the passage does not restrict this to a particular sense or role of coffee (it discusses consumption generally). One very minor consideration: 'valid_from' is null, which is appropriate since the passage does not specify a precise starting date, only 'for many years before the war.'
