What is a reader doing when they are delineating an argument

When a reader is delineating an argument, they are analyzing and breaking down the structure and content of the argument. They are identifying the main claims being made, the supporting evidence or reasons provided, and the logical connections between these elements. Furthermore, they may assess the validity and soundness of the argument, evaluating its strengths and weaknesses. Delineating an argument involves understanding its components and organization to gain a clearer understanding of its intended purpose and effectiveness.
