Describe the similarities and differences between physical evidence, documentary evidence, demonstrative evidence, and testimony

Hello! I took this course (forensic science, right?) about a year back so forgive me if my memory is a little rusty but I can answer this with some confidence. I'll define each of these types of evidence, hope this helps!

1. Physical evidence is a pretty much exactly what it sounds like; it's really any material object or matter that ties into the investigation. For example, fiber found at the scene of the crime would be considered physical evidence, as would blood splatters or biological matter.

2. Documentary evidence, again, is basically what it sounds like. It's a document that played a role in what is being investigated or hashed out in a court of law. This could be someone's last will and testimony, a printed email, or even a receipt.

3. Demonstrative evidence is a form of evidence that could explain what happened and how, such as a graph, model, or pictures.

4. Testimony is a statement taken from a person educated in the subject that is being discussed. Giving testimonies is one of the roles of a forensic scientists, as their opinions carry weight due to their education and experience.

I hope this helps! Good luck!

innocence can be defined as the lack of sin, relating it with the lack of guilt, also it can be a synonime of naivety. most people agree that sins are made out of experiences, intentionally or not, as well as you stop being naive once certain things happen to you throughout your life. so, with this explained, the chosen answers are:

when the boy saw the effects of war, he no longer viewed life as innocent.

the loss of innocence is a result of gaining experience and making mistakes.

one way to define innocence is as a lack of worldly experience or sophistication.
