This question tests AP Chinese Language and Culture skills: identifying organizing and rhetorical structures (specifically, recognizing and interpreting rhetorical devices and strategies in context). Comparison and contrast as rhetorical devices help readers understand new concepts by relating them to familiar ones. Recognizing these structures aids in understanding the author's intent and argumentation style. In this news article about AI homework feedback, the author employs comparison throughout: AI versus traditional grading (faster but needs review) and AI versus online classes (classroom interaction remains key). Choice A is correct because it accurately identifies the use of comparison/contrast (对比) as the dominant organizational pattern, evident in phrases like '与传统批改相比' and '与网课相比'. This demonstrates an understanding of how comparative structures clarify advantages and limitations. Choice B is incorrect because the text doesn't start with results then trace back to causes; it maintains a comparative framework throughout. To help students: Teach them to identify comparison markers (相比、与...比较、但是). Practice recognizing when authors use comparison to evaluate new technologies or methods. Watch for: missing explicit comparison signals, confusing evaluation with pure cause-effect reasoning.

This question tests AP Chinese Language and Culture skills: identifying organizing and rhetorical structures (specifically, recognizing and interpreting rhetorical devices and strategies in context). Repetition and parallelism as rhetorical devices create rhythm, emphasis, and memorability in persuasive speeches. Recognizing these structures aids in understanding the author's intent and argumentation style. In this cultural preservation speech, the author employs repetition explicitly mentioned in '我们反复呼吁"留下来"，因为重复能加强节奏与记忆' and parallel structure in '学起来、用起来、传下去' to reinforce the call to action. Choice A is correct because it accurately identifies repetition (重复) as the primary rhetorical strategy for strengthening the appeal, as the text itself explains how repetition enhances rhythm and memory. Choice B is incorrect because while the speech is passionate, it doesn't employ hyperbole or exaggeration as its main device. To help students: Teach them to recognize when authors explicitly name their rhetorical strategies. Practice identifying parallel structures and repeated phrases that create cumulative effect. Watch for: confusing emphasis with exaggeration, missing self-referential explanations of rhetorical choices.
