Supporting Details and Inferences
核心知识
Evidence first, interpretation second. On ACT Reading, a correct detail or inference answer is either directly stated or supported by a short, defensible chain from the passage.
深入理解
This topic still sits inside Key Ideas and Details. Whether the passage is literary narrative, humanities, social science, or natural science, the rule stays the same: start with what the text gives you and stop before you invent more.
Most right answers do one of two things:
- They restate an important detail accurately.
- They make a careful inference the passage clearly supports.
Most wrong answers break the chain at a predictable spot:
- Wrong person: the passage attributes the idea to someone else.
- Wrong time: the detail is real but tied to a different stage, event, or sequence.
- Cause and effect reversed: the choice keeps the facts but scrambles the logic.
- Extra assumption: the answer adds a reasonable-sounding step the passage never earns.
Paired passages and visual-supported passages do not change the rule. Keep track of which text supplies which evidence, and make sure a figure shows what the answer claims it shows.
