Central Ideas and Summaries
ACT central-idea and summary questions ask what the passage mainly says, not which detail stands out most.
Core Idea
Step back from vivid detail. Central-idea and summary questions ask what the passage is mainly doing overall, not which example sounds most memorable. The right answer covers the passage's real scope without drifting into a bigger claim the author never develops.
Understanding
In Key Ideas and Details, the main idea may appear as a theme in literary narrative, a claim in humanities or social science, or a central explanation in natural science. The surface changes, but the job does not: figure out what most of the passage is doing.
Use this quick scan:
- Whole-passage test: pick the choice that fits most of the passage, not just one vivid paragraph.
- Too narrow: a real example, scene, or statistic shows up, but it only supports the larger point.
- Too broad: the choice turns a local passage into a sweeping statement about society, science, or human nature.
Paired passages can still test central ideas. Identify each passage's point before deciding whether the question asks about one text or the shared issue. Do not let one vivid detail replace the passage's main claim.
