A reader is analyzing the claim and evidence when they are delineating an argument.
When a reader is delineating an argument, they are analyzing the claim and evidence. Delineating an argument means carefully examining the structure and content of the argument to understand its main point and supporting evidence. To do this, the reader looks closely at the claim being made, evaluates the evidence provided to support the claim, and considers the logical connections between different parts of the argument. By analyzing the claim and evidence, the reader is able to gain a deeper understanding of the argument's strengths, weaknesses, and overall effectiveness.
