The principal sources of supply up to that time were the Dutch East Indies, Arabia, Haiti, and Jamaica
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact quote 'The principal sources of supply up to that time were the Dutch East Indies, Arabia, Haiti, and Jamaica' explicitly states that coffee was supplied from these four locations prior to 1789.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim and accurately supports the assertion. Viewpoint, stance, sentiment, and temporal qualifiers are all correct. However, the context field should not be empty - the passage discusses coffee in the context of import duties and trade history (specifically "up to that time" referring to 1789), so context could be more explicitly marked as relating to the commodity trade/import context, though this is a minor issue. Overall score reflects strong fidelity with only a very minor contextual annotation concern.
