What can facts be proven by in investigations?

In investigations, facts can be substantiated through various forms of evidence, making the correct choice all-encompassing in its acknowledgment of these different validation methods. Documentation serves as a vital source of evidence, providing written records such as reports, records, or official papers that detail events or conditions relevant to the investigation. This type of evidence can offer a factual basis for claims made during the inquiry.

Testimony involves the spoken accounts of witnesses who provide their observations or experiences relating to the situation under investigation. The reliability of testimony can vary, but when corroborated with other evidence, it can significantly bolster the findings of an investigation.

Photographs are powerful tools in investigations, capturing visual evidence that can depict scenes, objects, or incidents. They help to recreate and substantiate details that may be difficult to convey through words alone.

When all these methods of proving facts are combined—documentation, testimony, and photographs—they create a comprehensive framework of evidence that supports thorough and accurate investigations. Thus, acknowledging all three as valid means to prove facts reflects a robust understanding of investigative practices.
