Determining Central Ideas, Inferences, and Textual Evidence
The GED RLA exam tests your ability to comprehend informational and literary texts (75% informational / 25% literary).
1. Central Idea vs. Topic vs. Supporting Detail
- Topic: The general subject matter in 1–2 words (e.g., Renewable Energy).
- Central Idea (Main Idea): The core point or overarching argument the author makes about the topic (e.g., Transitioning to solar power offers long-term economic savings despite high initial installation costs).
- Supporting Detail: Specific facts, statistics, quotes, or anecdotes that prove the central idea.
2. Making Valid Inferences
An inference is a logical conclusion based on text evidence + reasoning.
- Valid inferences are directly grounded in statements in the text.
- Avoid assumptions or outside knowledge not supported by the passage.
