Final answer:
A document in evidence can include not only written text but also visual and audio information, making the correct answer to the first part 'a) True'. The term closest to 'hypothesis' is 'd) suggestion', as it represents a tentative idea yet to be tested.
Step-by-step explanation:
The definition of "document" used in evidence can indeed encompass materials that contain verbal, visual, and audio information. Therefore, the correct answer to the first part of the question is a) True. A document in the context of evidence is not limited to written words but also includes materials with visual or audio information that can be admitted as evidence in a legal context.
As for the word closest in meaning to the hypothesis, contrary to a fact, which is a statement that can be proven correct or accurate based on evidence and data, a hypothesis is a proposed explanation made based on limited evidence as a starting point for further investigation.
Thus, the closest word in meaning to the hypothesis from the provided options is d) suggestion.
