Final answer:
The author develops the primary claim in paragraph 4 by presenting a claim supported with evidence and followed by an analysis which explains how the evidence supports the thesis.
Step-by-step explanation:
The author develops the primary claim of the article in paragraph 4 through a structured approach. Initially, the paragraph begins with a topic sentence that transitions from the preceding paragraphs and indicates what is to be discussed. Following this, a specific claim tied to the thesis statement is presented.
To substantiate this claim, evidence is provided, which includes quotations, paraphrases, or data pertinent to the argument. Finally, an analysis is conducted where the author elucidates how the evidence supports the claim and how it propels the argument forward towards the conclusion.
This systematic structure helps the author to build a convincing narrative, effectively supporting the thesis statement of the article.
