Match each paragraph description from a hypothetical scientific passage to its primary rhetorical function within the passage's logical structure.
- Paragraph 1 describes a long-held scientific consensus regarding the extinction of the dinosaurs.To present an established viewpoint that serves as the baseline for the passage's subsequent discussion.
- Paragraph 2 introduces anomalous geological data discovered in the 1980s that cannot be explained by the consensus.To introduce empirical evidence that challenges an established viewpoint.
- Paragraph 3 explains the physical mechanism by which the anomalous data (an asteroid impact) could have caused a mass extinction.To detail the theoretical causal process underlying a newly introduced hypothesis.
- Paragraph 4 considers and dismisses volcanic activity as an alternative explanation for the anomalous data.To evaluate and reject a potential alternative explanation for the new findings.
Answer
Paragraph 1 matches presenting an established baseline. Paragraph 2 matches introducing challenging evidence. Paragraph 3 matches detailing a causal process. Paragraph 4 matches rejecting an alternative explanation.
Each paragraph in a passage serves a specific rhetorical purpose. Paragraph 1 establishes the baseline consensus. Paragraph 2 introduces the challenging empirical evidence. Paragraph 3 explains the causal mechanism of that evidence. Paragraph 4 eliminates a competing alternative to solidify the new hypothesis.
