How is a complex argument defined?

A complex argument is characterized by its inclusion of multiple premises that often lead to intermediate conclusions, which are essential for forming a more substantial overall conclusion. This structure allows for a richer analysis and understanding of the argument, as it weaves together different lines of reasoning that support the final claim.

This format is particularly valuable because it can demonstrate the interconnections among various ideas and propositions, showing how they contribute to the main conclusion while possibly offering alternative paths of reasoning within the argument itself. Furthermore, intermediate conclusions can help clarify the argument’s rationale and bolster its persuasiveness by addressing various aspects of the topic being discussed.

In contrast, a single premise would limit the complexity and depth that can be achieved in an argument, while being concise does not inherently relate to the argument's complexity or how many premises it contains. Additionally, multiple interpretations can often arise from complex arguments, making option D less applicable. Thus, the choice that accurately captures the essence of a complex argument is the one that highlights the presence of multiple premises and intermediate conclusions.
