ACT Reading Integration of Knowledge and Ideas: arguments, evidence, fact versus opinion, and comparison - complete overview

Integration of Knowledge and Ideas is the smallest and most analytical of the three ACT Reading reporting categories, about 13 to 23 percent of the section. It groups the skills of weighing what a passage argues, and it is where the paired-passage part lives. This site breaks the category into four dot points, from analyzing an argument to comparing two passages. This overview maps the skills, how they connect, and how to study them.

The four Integration of Knowledge and Ideas skills

Each skill is a way of weighing a passage's claims.

• Analyzing arguments and claims. Identifying the central claim, the reasons, the evidence, and the counterclaim. See analyzing arguments and claims.
• Evaluating evidence and reasoning. Judging how well evidence supports a claim and spotting reasoning that does not follow. See evaluating evidence and reasoning.
• Fact versus opinion. Telling a verifiable statement from a judgement, and using the distinction to weigh claims. See fact versus opinion.
• Comparing two passages. Reading a pair for shared subject and differences, and inferring how one author would respond to the other. See comparing two passages.

The thread through every skill: weigh, do not just read

Two ideas tie the category together. The first is judgement: these questions ask not only what a passage says but how well it makes its case, whether evidence supports a claim, whether reasoning follows, whether support is fact or opinion. The second is keeping things straight: the central claim apart from its support and counterclaims, fact apart from opinion, and, in paired passages, one author's view apart from the other's. Read to weigh, and keep every claim attributed, and the most analytical category in the section becomes a set of clear tests.

How the skills are tested

• Argument questions: the central claim, a supporting reason, or the role of a counterclaim.
• Evidence and reasoning questions: which detail best supports a claim, or why a conclusion does not follow.
• Fact-or-opinion and comparison questions: classifying a statement, or naming how two passages relate and how one author would respond.

How to study Integration of Knowledge and Ideas

1. Find the claim first. For any argument, state the position the whole passage defends before judging it.
2. Demand earned conclusions. Ask whether the evidence is relevant and sufficient and whether the reasoning leaps.
3. Test for verifiability. Sort statements into fact and opinion by whether they can be checked.
4. Attribute everything in a pair. Label each claim A or B so the two passages never blur.
5. Infer responses from stance. To predict one author's reaction, apply their stated view to the other's claim.
