Identifying Main Idea & Drawing Inferences

Extract central themes, distinguish facts from opinions, recognize informational text structures, and draw sound inferences.

🎯 Core Competencies Covered

  • Formulating concise main idea statements that encompass the full passage.
  • Differentiating between valid text-based inferences and outside assumptions.
  • Recognizing organizational text structures (cause/effect, compare/contrast).
  • Assisting students in decoding unfamiliar academic vocabulary from context.

Identifying Main Idea, Inferences & Text Structure

Reading comprehension questions test your ability to extract meaning efficiently, understand authorial intent, and assist students with decoding informational text structures.

1. Main Idea vs. Supporting Detail

The Main Idea is the central umbrella argument of the passage. A Supporting Detail provides factual evidence, examples, or statistics that substantiate that main idea. If an answer choice only describes one paragraph or one example, it is a supporting detail, not the main idea.

2. Drawing Valid Inferences

An inference is a logical deduction based on what is directly stated in the text. To avoid inference traps:

  • Never rely on outside personal knowledge not mentioned in the text.
  • Avoid answer choices with unstated generalizations or extreme assumptions.
  • Confirm that the text provides concrete textual evidence pointing directly to your conclusion.
