judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'on June 1, 1887, December contracts sold at twenty-two and one-quarter cents--a new high price record.' All elements (subject, predicate, object, and time) are explicitly stated without modification or inference.
- 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 assertion without attribution to a named source). The stance 'asserts' matches the declarative nature of the passage. The sentiment is appropriately neutral for a factual price statement. The time qualifiers match exactly: 'on June 1, 1887' with valid_from '1887-06-01' and valid_to null (no end date specified). The context is empty, which is appropriate as the passage does not restrict the claim to a particular sense or role. The quote appears verbatim in the passage and directly supports the claim.
