  First strawboard (1881)

  judge verdicts (2)

  • groundedness 1.00 pass — The claim is directly stated in the passage under 'Containers' where it explicitly lists 'First strawboard (1881), 471', confirming that strawboard was first used as a container in 1881.
  • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (the passage itself makes this assertion without naming a source). The stance 'asserts' is appropriate as the passage presents this as a factual claim. The sentiment is neutral, matching the passage's matter-of-fact tone. The time qualifier correctly identifies 1881 as when the first strawboard container was used, with valid_from set to 1881 and valid_to as null (no end date given). The context 'container history' accurately reflects the passage's categorization under 'Containers' as a historical notation about container development. The quote 'First strawboard (1881)' appears verbatim in the passage and directly supports the claim.
