What is direct evidence?

Direct evidence refers to evidence that can support the truth of an assertion directly, without needing any inference or presumption. This type of evidence is typically derived from the direct observations of a witness, which encompasses what that person has seen, heard, or otherwise experienced first-hand. For example, if a witness testifies that they saw a crime happen, their account is considered direct evidence because it comes from personal sensory experience.

In contrast, circumstantial evidence would involve making inferences based on the circumstances surrounding an event rather than direct observation. Other choices describe different types of evidence but do not correctly define direct evidence. Theoretical evidence implies a hypothetical nature that is not grounded in personal experience. Similarly, expert testimony is typically used to interpret or explain complex evidence rather than to present direct evidence itself.
