Which type of evidence is often the only evidence available to distinguish between consent/non-consent and levels of incapacitation?

• A. Documentary
• B. Physiological
• C. Eyewitness
• D. Circumstantial

Answer: (B)

The main idea is that incapacitation and consent hinge on actual ability to understand and decide, which is most reliably shown through objective impairment indicators. When a person’s capacity to consent is in dispute, physiological evidence such as toxicology results, blood alcohol concentration, or drug levels can prove they were impaired at the time. These measurable indicators provide concrete proof of impairment that isn’t easily disputed, even if there are few or conflicting statements about consent. Other types of evidence like documents, eyewitness accounts, or circumstantial clues can be helpful, but they’re more subjective and can be limited or unreliable, especially if there’s no clear communication or memory of the events.
