judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Jekiel and Isaac E. Tone began the business of Tone Bros. at Des Moines, Iowa, in March, 1873.' All details (subject, predicate, object, and time) 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 states the fact). The stance is properly marked as 'asserts' since the passage presents this as fact. The sentiment is neutral, matching the passage's objective tone. The time qualifier correctly specifies March 1873 with normalized dates in valid_from. The context is appropriately empty since the passage provides no restricting sense or role for the business. The quote is verbatim from the passage and directly supports the claim that Jekiel Tone (along with Isaac E. Tone) began Tone Bros. in March 1873.
