Number of (1839)
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. Under the Vienna section, there is an explicit entry stating 'Number of (1839), 52', which confirms that there were 52 coffee houses in Vienna in 1839.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (as an index entry without named source attribution). The stance 'asserts' matches the factual presentation. Sentiment is neutral. The time qualifier correctly specifies 1839 matching the passage's parenthetical notation. The context 'Vienna in 1839' accurately reflects the passage's restriction of this claim to Vienna. The quote 'Number of (1839)' appears verbatim in the Vienna section and directly supports the numerical claim.
