What is it?
Information and Ideas questions ask you to locate, interpret, evaluate and combine information from short texts and from graphics such as tables and graphs. Typical tasks are finding the central idea, finding the detail that supports a claim, and making a logical inference.
Everything you need is in the passage. The correct answer is always supported by the text, even if it paraphrases it.
Key formulas and ideas
- Central idea: the main point of the whole passage, not a single detail.
- Command of evidence: choose the detail or data that best supports (or weakens) a given claim.
- Inference: a conclusion that must be true, or is very likely, based on the passage.
- Wrong answers are often too strong, too narrow or only partly true.
Worked examples
Example 1: Central idea
Question: A passage explains that bees pollinate crops, that bee populations have fallen, and that farmers are changing practices to protect them. What is the central idea?
- The passage links bees to crops and describes a response.
- The main point is broader than any single detail.
Answer: Falling bee populations affect agriculture, so farmers are adapting
Example 2: Choosing evidence
Question: A claim says 'Students who sleep more tend to score higher.' Which data supports it: (a) a table showing scores rising with hours of sleep, or (b) a table of hours of homework?
- The claim links sleep and scores.
- Only option (a) shows both variables.
Answer: (a) the table linking sleep and scores
Example 3: Inference
Question: A passage says 'The museum doubled its opening hours and visitor numbers rose sharply.' What can be inferred?
- Longer hours were followed by more visitors.
- The passage suggests, but does not prove, a link.
Answer: Longer opening hours may have helped attract more visitors
Common mistakes
- Choosing an answer because it sounds true in real life instead of being supported by the passage.
- Picking a detail as the main idea.
- Choosing answers with words like 'always' or 'never' without support.
- Misreading the title or axes of a graph.

Frequently asked questions
What should I do with tables and graphs?
Read the title, axes and units first, then find the specific data the question asks about.
Can I use outside knowledge?
Base your answer on the text. Outside knowledge can mislead you.
