Final answer:
Support in Stephen Toulmin's model of logos-based arguments includes observations that relate directly to the claim, and consist of empirical evidence and logical reasoning.
Step-by-step explanation:
According to the three-part model developed by Stephen Toulmin to explain logos-based arguments, the correct understanding of 'support' within this model is that it includes observations relating to what is stated in the claim. Support in an argument provides the necessary backing to justify the claim being made. This support often consists of empirical evidence, such as facts and data, as well as logical reasoning that demonstrates the coherence of the claim with established knowledge.
It's essential to identify the statements or premises that serve as the foundation for the conclusion in any logical argument. Good arguments feature premises that align with the rules of logic, such as necessity and sufficiency. Should these premises and their connections to the conclusion be strong, they enhance the overall persuasiveness and validity of the argument being put forth.
