Final answer:
A statement that is designed to convince an audience that something did or did not occur is a proposition of fact. It is different from propositions of value or policy and is based on the ability to be proven true or false, which is key in persuasive arguments and academic research.
Step-by-step explanation:
In the context of the types of propositions, a statement that is designed to convince an audience that something did or did not occur is a proposition of fact. This type of proposition on the veracity of a claim, allowing you to come to a judgment about its truthfulness. Because propositions of fact are assertions about reality that you aim to prove or disprove, they are integral to disciplines that rely on evidence and demonstration.
A proposition of fact is distinguishable from other types of propositions such as propositions of value, which focus on the worth or importance of something, and propositions of policy, which advocate for a particular course of action. When dealing with facts in arguments, it's important to differentiate between objective truths and subjective opinions. Since facts can be verified or proven false, they serve as solid ground for persuasive arguments and are used extensively in research and academia to support or refute hypotheses and theories.
