Difficulty: EasyRhetorical Structure and Sentence Function

Based on the rhetorical analysis of the passage description below, fill in the blank with the appropriate functional term.

Answer:The passage begins by presenting a long-held assumption among paleontologists regarding dinosaur metabolic rates. In the second sentence, the author cites recent isotopic analyses of fossilized tooth enamel that directly challenge this assumption. Structurally, the second sentence serves primarily as a 【counterexample】 to the traditional view.

Answer

The second sentence functions as a counterexample (or rebuttal/refutation/counterargument) to the traditional view.
The second sentence introduces specific empirical data (isotopic analyses) that directly opposes and undermines the long-held assumption presented in the first sentence. Therefore, its rhetorical role is to act as a rebuttal, counterexample, or refutation.

Step-by-Step Solution

1
Identify the claim made in the first sentence.
The first sentence establishes a traditional assumption/viewpoint held by paleontologists.
Understanding the baseline assertion is necessary to determine how subsequent sentences relate to it.
2
Analyze the relationship between the second sentence and the first sentence.
The second sentence introduces new isotopic evidence that contradicts and challenges the initial assumption.
Determining structural relationships requires evaluating how evidence interacts with established claims.
3
Determine the rhetorical function of the second sentence.
Since it introduces opposing evidence against the established view, its primary function is a counterexample or rebuttal.
A sentence introducing evidence against a hypothesis serves to challenge or refute that hypothesis.
