judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The illustration caption explicitly lists '1--W.F.

- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage.

In the spring of 1862, Albert A. Sprague came to Chicago from Vermont
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage's opening sentence: 'In the spring of 1862, Albert A. Sprague came to Chicago from Vermont.' The subject, predicate, object, and time period all match exactly with no additional knowledge or over-generalization required.
- 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 biographical fact. The time qualifier correctly specifies 'spring of 1862' with normalized dates (1862-03 to 1862-05) matching the temporal scope given in the passage. The context is empty, which is appropriate as the passage provides no restricting context. The quote appears verbatim in the passage and directly supports the claim.
Samuel moved to Chicago to open a branch
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Samuel moved to Chicago to open a branch.' The passage confirms Samuel R. was one of Alvan's sons admitted in 1861 and later moved to Chicago for this purpose, with the timing consistent with after Alvan's death in 1873.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The viewpoint, stance, and sentiment are all appropriate for an author's neutral assertion. The context is correctly left empty as the passage provides none. The quote is verbatim and accurate. However, the time qualifier has a minor issue: the passage states 'Samuel moved to Chicago to open a branch. He died in 1878,' which establishes the move occurred before 1878, but the passage places it after Alvan's death in 1873. The valid_from date of 1873 is reasonable given the narrative sequence, but valid_to should potentially be capped at 1878 (his death) rather than left null, as the passage does provide an endpoint for his life. If null is intended to mean 'ongoing/unknown beyond the stated period,' this is acceptable but slightly less precise than it could be.
