What is the role of sub-claims in a subordinative argument structure?

The correct answer highlights the function of sub-claims in a subordinative argument structure, which is to support another claim that ultimately backs the main claim. Sub-claims serve as essential components within an argument, reinforcing the overall thesis or assertion by providing additional layers of evidence or reasoning. They act as intermediaries that connect more specific assertions to the broader main claim, ensuring that the argument is well-supported and logically sound.

In an effective argument, the main claim is often too broad to stand alone without substantiation. Sub-claims break down the argument into manageable parts, each contributing unique evidence or reasoning that collectively strengthens the overall position.

By fulfilling this supportive role, sub-claims ensure that the argument remains coherent and persuasive, effectively guiding the audience through the nuances of the reasoning presented. Thus, the interaction between the main claim and sub-claims creates a more robust and compelling argument structure.
