In Tuyuca and other East Tucanoan languages of the northwest Amazon basin, every finite verb requires an obligatory grammatical suffix specifying the speaker’s source of evidence. These morphemes distinguish among direct visual observation, non-visual sensory perception, inference drawn from physical traces, hearsay, and assumed knowledge. Whereas non-indigenous legal proceedings typically rely on adversarial cross-examination to scrutinize a witness’s credibility, traditional judicial discourse among Tuyuca speakers rarely involves overt challenges to personal integrity. Instead, speakers select evidential suffixes to ensure they do not overstate the certainty of their claims, and listeners assess assertions through the specific evidential category chosen. Consequently, statements marked with visual evidence suffixes are treated as inherently robust, requiring no auxiliary rhetorical corroboration to establish that the speaker directly witnessed the event.
Which of the following is most strongly supported by the passage?

- A Tuyuca speaker who directly witnessed an event does not need to employ separate rhetorical assertions to convey that their claim is grounded in first-hand visual experience.Answer
- CNon-indigenous legal proceedings rely on adversarial cross-examination primarily because Western languages lack grammatical mechanisms for indicating evidence sources.
- DTuyuca listeners evaluate assertions derived from tangible physical traces as carrying the same degree of certainty as direct visual observations.
- EJudicial disputes arise far less frequently in Tuyuca-speaking communities than in societies that utilize adversarial courtroom models.
