In 1814, however, the first crude steamboat had begun to carry freight on the river
judge verdicts (2)
- groundedness 0.80 pass — The claim is well-supported by the passage. The passage states 'In 1814, however, the first crude steamboat had begun to carry freight on the river.' The only minor issue is that the claim says 'Mississippi Valley river' while the passage refers to 'the river' (contextually the Mississippi River), but this is a negligible rewording that maintains accuracy.
- qualifier_fidelity 0.85 pass — Minor context qualifier issue: The claim specifies 'Mississippi Valley river' but the passage says 'the river' (referring to the Ohio/Mississippi river system in context). The quote supports 'the river' generally, not specifically 'Mississippi Valley river' as the object. However, this is a minor contextual imprecision since the passage does establish the Mississippi Valley context. All other qualifiers are faithful: viewpoint is correctly 'author', stance is 'asserts', sentiment is 'neutral', time '1814' is accurate, and the quote appears verbatim and supports the claim. Consider revising the object to just 'the river' for stricter fidelity.
