Which level of proposition would involve showing that a specific activity occurred, according to evidence?

The activity level of proposition focuses specifically on demonstrating that a particular action took place, supported by the available evidence. This often involves establishing a connection between the evidence and the activity in question, thereby affirming that the event or behavior actually occurred within the context of an investigation.

At the activity level, forensic analysis may incorporate various types of evidence, such as witness statements, physical evidence, or digital data, to substantiate claims about specific actions. This level is pivotal in criminal investigations where proving that an activity occurred can be critical for building a case against an individual or explaining the sequence of events in a forensic context.

The other levels of propositions, while related, serve different purposes. For instance, source level may involve identifying the origin of certain evidence, such as the source of a digital file, and sub-source level would delve deeper into the category or specifics of a source. The offence level pertains to the broader legal implications of a crime but does not focus specifically on whether an activity occurred based solely on the evidence. Therefore, the activity level is the appropriate choice for addressing the occurrence of a specific activity supported by evidence.
