  sinapes nigra, brown or black mustard

  judge verdicts (2)

  • groundedness 1.00 pass — The claim is directly supported by the passage, which explicitly states 'sinapes nigra, brown or black mustard' when describing the two species of mustard plants. The naming relationship is clearly asserted in the text.
  • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The claim correctly attributes the statement to the author (not a named source), uses neutral stance and sentiment, applies no time qualifiers (correctly null), includes no context restriction, and the quote appears verbatim in the passage supporting the claim about sinapis nigra being called brown or black mustard.
