This machine had the ascending steam tube on the exterior
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Jacques Augustin Gandais, a manufacturer of plated jewelry in Paris, produced a really practicable pumping percolator. This machine had the ascending steam tube on the exterior.' The exact wording is used and all details are supported.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as historical fact without attribution to a named source). The stance is 'asserts' which matches the passage's straightforward presentation. The sentiment is neutral, appropriate for a factual technical description. The time 'when': 1827 matches the passage's explicit statement about Gandais's percolator. The context is empty, which is appropriate as the passage does not restrict this to a particular sense or role. The quote appears verbatim in the passage and directly supports the claim about the pumping percolator's design feature.
