Study Strategies for Information and Ideas
Read for the main claim first
Before looking at the answer choices, identify the author’s central argument or the passage’s primary purpose. On the Digital SAT, passages are short (25–150 words), so you can usually pinpoint the main idea in one or two sentences. Summarize it in your own words before moving to the question. This prevents you from being tricked by choices that are true details but miss the bigger picture.
Annotate evidence boundaries
For Command of Evidence questions, the correct answer must be directly supported by the text. Train yourself to underline or mentally note the exact sentence that proves each claim. If you cannot point to a specific line, the answer is likely wrong. Practice distinguishing between what the passage states and what you infer—the SAT rewards precise reading, not speculation.
Use process of elimination on data questions
Quantitative Command of Evidence questions pair a claim with a table, chart, or graph. Start by reading the claim, then check each answer choice against the data. Eliminate any option where the numbers contradict the claim. Often two choices will look similar—compare the specific figures to break the tie. Accuracy here comes from patience, not speed.
Practice with varied passage types
Information and Ideas questions appear across literary, social science, and natural science passages. Build comfort with all three by reading a mix of short-form nonfiction. Pay special attention to how authors use evidence differently in each discipline—scientists cite data, historians cite documents, and literary critics cite textual details.
Common Mistakes to Avoid
Choosing an answer that is true but does not answer the question
A detail from the passage may be factually correct but irrelevant to what the question asks. Always re-read the question stem after selecting your answer to confirm it matches.
Confusing inference with assumption
An inference must be directly supported by the passage. If you need outside knowledge or a logical leap beyond the text, the answer is likely wrong.
Misreading data in tables and graphs
Students frequently read the wrong row, column, or axis. Slow down and confirm the labels before extracting any numbers from a data display.

The city of Riverside recently installed solar-powered streetlights along its main boulevard. These new lights cost 40% less to operate than the old electric streetlights they replaced. Additionally, the solar lights require less frequent maintenance because they have fewer mechanical components. The city council plans to expand the solar streetlight program to residential neighborhoods next year.
Based on the text, what can most reasonably be inferred about the city council's decision to expand the solar streetlight program?
