Which of the following definitions best describes direct evidence?

The definition of direct evidence is best described as original evidence of an event that was directly perceived. This type of evidence directly supports a fact without the need for inference, as it originates from a witness who saw, heard, or experienced the event firsthand. For example, if a witness testifies that they saw a crime occur, their testimony is direct evidence because it is an immediate, firsthand account of the event in question.

Other options reflect different types of evidence but do not accurately capture the essence of direct evidence. For instance, evidence from which facts can be inferred refers to circumstantial evidence, which relies on inference rather than direct observation. Evidence presented in court other than the original documents might suggest secondary forms of evidence, which are not classified as direct. Finally, testimony that is secondhand describes hearsay, which is not direct evidence because it does not involve firsthand knowledge. Thus, the best definition provided is the one that describes direct evidence as originating from firsthand perception.
