What is the primary purpose of demonstrative evidence in court?

1. To present witness statements

2. To demonstrate and clarify facts for the jury

3. To serve as physical artifacts of the crime

4. To establish a juror's bias

The correct answer is: To demonstrate and clarify facts for the jury

The primary purpose of demonstrative evidence in court is to demonstrate and clarify facts for the jury. This form of evidence is essential in helping jurors visualize and understand complex information, making it more accessible and relatable. Demonstrative evidence can take many forms, such as diagrams, charts, photographs, or models, which illustrate key aspects of the case. By providing a visual representation of the facts, it aids jurors in comprehending the evidence and reinforces the arguments made by attorneys. This clarity is crucial for jurors to make informed decisions based on the evidence presented during the trial. While witness statements serve to provide personal accounts of events, and physical artifacts can support those accounts, their main purposes differ from the explanatory role that demonstrative evidence plays. Additionally, establishing a juror's bias is outside the scope of what demonstrative evidence is intended to address, focusing instead on the clarification of factual matters pertinent to the case.
