In which argument configuration do claims add letters due to their dependence on one another?

In this context, the concept of argument configuration relates to how different claims are structured in relation to each other. The correct answer highlights the subordinative structure of arguments, which is characterized by claims that are dependent on one another, forming a hierarchical arrangement.

In subordinative arguments, the primary claim is supported by secondary claims or evidence, leading to a situation where the latter cannot stand alone without the former. Each dependent claim effectively requires the support of a higher claim in the hierarchy, hence, they "add letters" as they showcase their relationships and dependencies in the logic of the argument.

This type of organization is useful because it allows for a clear understanding of how various points are interconnected, emphasizing the flow of reasoning from more generalized premises down to specific conclusions. This contrasts with other configurations, where claims might operate independently or in coordination without such dependency.

Understanding this structure is critical in public debate as it helps debaters construct logical frameworks that effectively support their positions through clear, interdependent arguments.
