Guard the Sentence Core

Identify the subject and verb, then make sure punctuation does not split them or add extra ideas.

  • Find the subject + verb first. That is the sentence core.
  • Only add commas around extra information, never inside the core.
  • Re-read the sentence without the modifier to test clarity.

Why Synthesis and Data Integration Matters on the SAT

Beyond choosing a good transition word, some SAT Reading and Writing questions ask you to read a set of data and weave that evidence into a paragraph. These synthesis and data integration questions are among the most predictable on the entire test, and students who practice them routinely pick up 2–4 extra points. If you can read a bar graph and finish a sentence, you can master these.

This post will walk you through exactly what these questions look like, the strategy that makes them straightforward, and give you five practice questions that build from easy to medium difficulty. By the end, you'll have a repeatable process for turning data into points.

What Is Synthesis and Data Integration?

On the SAT, synthesis means combining information from two sources, usually a written passage and some form of data (a table, chart, or description of study findings). Data integration is the specific act of weaving quantitative evidence into a prose argument so the conclusion actually matches the numbers.

These questions typically give you a short passage (2–4 sentences) describing a study, survey, or trend. Somewhere in the passage, often at the end, there's a blank. Your job is to choose the sentence that accurately connects the claim in the passage to the data provided. That means the correct answer must do two things at once:

  • Be factually accurate, it cannot misstate, exaggerate, or ignore the data.
  • Function as a logical transition or conclusion, it must flow naturally from the sentences before it.

A common misconception is that these are pure "reading comprehension" questions. They're not. They're about precision. The SAT isn't testing whether you understood the general idea, it's testing whether you can tell the difference between a sentence that sort of matches the data and one that matches it exactly.

The Strategy: Eliminate, Then Connect

Here's a repeatable approach that works on virtually every synthesis question:

  1. Read the passage first. Understand the claim or argument being made. What is the paragraph trying to say?
  2. Read the data carefully. Note specific numbers, trends, and categories. Pay attention to which group is higher, which is lower, and by how much.
  3. Eliminate answers that misstate the data. This is where most of your work happens. Usually 2 of the 4 choices contradict the data outright, wrong numbers, reversed trends, or overgeneralizations. Cross them off.
  4. Choose between the remaining options based on logical flow. Among the factually accurate answers, pick the one that serves as the best transition or conclusion for the paragraph.

Time-saving tip: Start with elimination. Don't waste time deliberating between all four choices. The fastest path to the right answer is removing the wrong ones first. On most of these questions, two choices will have a clear factual error that takes only seconds to spot.

Watch Out for Qualifier Words

  • Dangerous qualifiers: "all," "every," "only," "none," "always," "never," "clearly," "proves", these are almost always too extreme for a single study or data set.
  • Safe qualifiers: "may," "suggests," "some," "tends to," "on average," "appears to", the SAT favors this kind of measured, precise language.

When you see an answer choice that says something like "all students should" or "this proves that," treat it as a red flag. A single study almost never justifies that kind of certainty, and the SAT knows it.

Practice Synthesis and Data Integration with SAT-Style Questions

Let's put the strategy to work. These five questions progress from easy to medium difficulty. For each one, try to eliminate factually wrong answers first, then choose the best remaining option.

Passage
A researcher surveyed 400 high school students about study habits. The results showed that 68% of students who studied with background music reported feeling "focused," compared to 41% of students who studied in silence.

Which choice most effectively uses the data to complete the paragraph?

Passage
A 2023 report by the National Wildlife Federation tracked monarch butterfly populations across three regions. The Midwest saw a 12% decline, the Southeast saw a 4% increase, and the West Coast saw a 22% decline.
easy

Which choice most accurately synthesizes the data from the report?

Passage
Economists at a state university analyzed median household income and public library usage in 50 U.S. counties. Counties with median incomes below 40,000 averaged 8.2 library visits per resident per year, while counties above 75,000 averaged 5.1 visits. Counties in the middle range averaged 6.8 visits.
medium

Which choice best integrates the study's findings as a transition to further discussion?

Passage
A clinical trial tested two treatments for seasonal allergies. Treatment A reduced symptoms by 34% on average, while Treatment B reduced symptoms by 52%. However, Treatment B caused mild side effects, including drowsiness and dry mouth, in 28% of participants, compared to only 6% for Treatment A. A physician reviewing these results wrote:

Which choice most effectively synthesizes the findings from the trial?

Passage
A sociology study examined volunteer rates among three age groups. Adults aged 18–29 volunteered at a rate of 22%, those aged 30–54 at 31%, and those aged 55 and older at 27%. Notably, the 18–29 group contributed the most hours per volunteer, averaging 14.6 hours per month compared to 9.3 for the 30–54 group and 11.2 for the 55+ group.

Which choice most accurately completes the passage by synthesizing both sets of data?

Key Takeaways for Synthesis and Data Integration

  • Always check the data before picking an answer. Two or three choices will sound reasonable but contradict the actual numbers. Your first move should always be elimination.
  • Watch for qualifier words. "All," "every," "only," and "none" are almost always too extreme. The SAT favors measured language like "may," "suggests," and "some."
  • Synthesis means accounting for ALL the data. If a passage gives you three data points, the right answer won't ignore two of them. Beware of choices that cherry-pick.
  • These questions reward careful reading, not speed. Spend the extra 15 seconds verifying your answer against the data. That small investment almost always pays off.

Conclusion: The Core Rule for Synthesis and Data Integration

Synthesis and data integration questions are some of the most learnable points on the SAT Reading and Writing section. Unlike questions that depend on vocabulary or reading speed, these reward one simple habit: checking your answer against the evidence. Practice reading data carefully, eliminating answers that misrepresent it, and choosing the option that captures the full picture.

Remember: Read the data, eliminate the mismatches, and pick the answer that tells the whole story. Do that consistently, and these questions become reliable points in your pocket on test day.
