Differentiate between viewpoints and sources of information within a passage.
Separate a person's viewpoint from the evidence source being cited.
核心知识
Separate voices from evidence sources. A person's viewpoint, the author's framing, and cited data are not interchangeable.
深入理解
Keep viewpoint and evidence in separate buckets. ACT often places a narrator, quoted speaker, researcher, or data source in the same passage, and the trap is blending them together.
Check three things:
- Who judges: whose opinion or interpretation is this?
- What is observed or measured: what detail comes from data, field notes, or another record?
- Who reports it: is the author quoting, summarizing, or endorsing that source?
A field note, interview, graph, and author summary do not do the same job, even when they appear side by side.
分步讲解
- Identify each voice or source in the excerpt: author, narrator, quoted person, study, or data set.
- Decide which statements are viewpoints and which are observations or measurements.
- Match the answer that keeps speaker and evidence source in the correct roles.
常见误解
- Treating quoted language as the passage author's own position without checking attribution.
- Calling data a viewpoint or calling a personal judgment a measurement.
- Blending two sources together just because they appear in the same paragraph.
