ten cents for electric power
judge verdicts (2)
- groundedness 0.70 pass — The passage directly states that electric power has an operating cost of 'ten cents for electric power' per hundred pounds in retail roasting machines. The claim's wording 'costs approximately ten cents per hundred pounds' is a minor rewording that accurately captures this information from the text.
- qualifier_fidelity 0.80 pass — The claim is largely faithful to the passage. The quote 'ten cents for electric power' appears verbatim and accurately supports the claim about operating costs. However, there is a minor issue with the quote: the full context from the passage is 'the operating cost running from approximately eight cents per hundred pounds for gas fuel and ten cents for electric power.' The claim's quote omits 'the operating cost running from approximately' and the comparative context with gas fuel, which slightly misrepresents the complete qualifier structure. The predicate should more precisely be 'costs approximately' rather than just the quoted fragment. All other qualifiers (viewpoint as 'author', stance as 'asserts', sentiment as 'neutral', null time, and context as retail roasting operating cost) are faithful to the passage.
The roasting cylinder is generally revolved by electric power
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact wording: 'The roasting cylinder is generally revolved by electric power.' This is fully supported without any rewording or interpretation needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. Viewpoint is correctly attributed to the author (passage presents this as general knowledge about retail roasting machines, not attributed to a named source). Stance 'asserts' is appropriate as the passage states this as fact. Sentiment is neutral, matching the objective, technical tone. Time qualifiers are all null, which is correct since the passage provides no temporal information. Context correctly specifies 'retail roasting machines' as the passage discusses this in the section titled 'Small Roasters for Retail Dealers'. The quote appears verbatim in the passage and directly supports the claim.

- groundedness 1.00 pass — The claim is directly stated in the passage: 'The machines used are of the ball or cylinder type, employing gas fuel and turned by electric power.' The exact phrase 'turned by electric power' appears verbatim, and the subject 'roasting machines' is clearly established in context.
- 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 observation). The stance 'asserts' is appropriate as the passage states this as fact, not disputed. The sentiment is neutral, matching the descriptive tone. Time qualifiers are correctly null as the passage provides no specific temporal scope. Context is appropriately empty as there are no restrictive senses or roles specified.
