Integration of Knowledge & Ideas
Comparing paired passages, weighing arguments and reading visual data in text.
What it tests
Integration of Knowledge & Ideas questions ask you to compare paired passages, judge how well an author supports a claim, and connect a passage with data in a table or graph. You decide how ideas fit together — where authors agree, where they differ, and what the evidence actually shows.
How it shows up
- The Reading test is 36 questions in 40 minutes. You get four passages (literary narrative, social science, humanities and natural science), one of which is a pair of shorter passages. That’s about 10 minutes per passage, questions included.
- Integration of Knowledge & Ideas is the smallest Reading category, but the paired passage makes it hard to avoid.
- Look for stems like “Both authors would most likely agree that…”, “How would the author of Passage B most likely respond to…”, “Which claim is supported by the data in the table?”, and “Which claim is NOT supported by evidence?”.
Key rules & concepts
The content you actually need to know.
Paired passages
- Read Passage A and answer its questions, then Passage B and its questions, then the questions about both.
- Write one sentence for each author’s main claim.
- Note where they overlap (agree) and where they conflict.
Evaluating arguments
- Separate the claim (what the author wants you to believe) from the evidence (data, examples, expert quotes, anecdotes).
- Ask: does the evidence actually support the claim, or is something missing?
- Facts can be checked; opinions can’t. A claim with “the library has not tracked this” has no data behind it.
Data in the passage
- Read the title, column labels and units first.
- Match exact numbers — “more than quintupled” means more than 5 times as large.
- Data shows what happened, not necessarily why. Don’t turn a pattern into a cause unless the passage does.
How would the author respond?
- Find what the author actually says about that specific point.
- Choose the response that matches the author’s tone and strength — not a more extreme version.
Strategy & traps
Step by step
- 1Summarize each passage’s claim in one sentence.
- 2Mark where the authors agree and where they disagree.
- 3For “respond” questions, find the author’s own words on that exact point.
- 4For data questions, check every number in the choice against the table.
Mixing up the authors
A choice may be true for Passage A but asked about Passage B.
One-sided “both” answers
For “both authors agree,” the answer must be supported in BOTH passages.
Overreading data
A rising line shows change, not the reason for it.
Worked examples
Try each one first, then reveal the solution.
Passage A
Teenagers are not lazy; their body clocks are different. During adolescence, the body begins releasing melatonin, the hormone that signals sleep, later in the evening, which makes falling asleep before 11 p.m. genuinely difficult for many teens. When school begins at 7:30 a.m., the math is unforgiving: a student who falls asleep at 11 and wakes at 6 gets seven hours of sleep, short of the eight to ten hours that sleep experts generally recommend for this age group. Districts that have moved start times later have often reported better attendance and fewer students dozing in class. Starting high school at 8:30 or later is one of the rare policies that asks students to change nothing and still helps them.
Passage B
No one disputes that teenagers need sleep. The question is what a later bell costs, and who pays. In many districts, the same buses carry high school students first and younger children second; moving the high school start time can mean buying more buses or sending elementary students to school in the dark. A later dismissal also cuts into afternoon practice time and into the hours students can work part-time jobs, which some families depend on. A later start may still be worth these costs. But a policy that sounds free rarely is, and districts deserve an honest accounting before they change the clock.
Example 1
The main purpose of Passage A is to:
- Aargue for later high school start times based on teenagers’ sleep needs.
- Bexplain in detail how the body produces melatonin.
- Ccriticize teenagers for staying up too late.
- Dcompare bus schedules in different school districts.
Example 2
The author of Passage B would most likely respond to Passage A’s claim that later start times ask students “to change nothing” by saying that the claim:
- Ais accurate, because students would not need to change any habits.
- Boverlooks costs that later start times can place on districts, families and younger students.
- Cis false, because teenagers don’t actually need more sleep.
- Dproves that later start times should be adopted immediately.
Example 3
Both authors would most likely agree that:
- Alater start times have no costs.
- Belementary schools should start later.
- Cpart-time jobs are harmful to students.
- Dteenagers benefit from getting enough sleep.

Social Science: The Library of Things
1When the Brookhaven Public Library began lending power drills, sewing machines and ukuleles in 2021, some residents worried that the library was abandoning its mission. A library, they argued, is for books.
2Head librarian Dana Okafor sees it differently. “Our mission was never books,” she says. “It was access. Books were just the first expensive thing we could share.” A good drill can cost more than some families spend on groceries in a week, yet most drills are used for only a few minutes over their entire lives. Lending one, Okafor argues, is the same idea as lending a novel: the community buys it once, and everyone shares it.
3The numbers suggest residents agree. Since the program began, loans of non-book items have risen every year (see the table). Book loans have not collapsed, either. In fact, Okafor reports that many people who come in for a tool leave with a book as well, although the library has not tracked how often this happens.
4Critics have a fair point about space and staff time: a sewing machine takes up more shelf room than twenty paperbacks, and tools must be inspected after every return. Whether the program can grow without crowding out other services is a question the library has not yet answered.
Brookhaven Public Library loans per year
| Year | Book loans | Non-book item loans |
|---|---|---|
| 2021 | 84,200 | 1,150 |
| 2022 | 85,900 | 2,940 |
| 2023 | 83,700 | 4,610 |
| 2024 | 86,400 | 6,380 |

Question 5
Which new information would most directly help answer the question raised at the end of the passage?
