It’s essential that you can identify what kind of passage you’re reading. Each passage type has specific features to notice. If you know what to look for, you’ll find answers faster and save time.
It’s also important to remember the following:
We briefly discussed passage types previously. In this chapter, we’ll go into more depth so you can recognize them quickly on test day.
The first passage of the ACT Reading section is called a literary narrative passage. It may appear under a few different labels at the top of the page (e.g., prose fiction, fiction), but the same strategies apply.
A literary narrative is a short, often fictional story centered around characters. It focuses on the perceptions, observations, feelings, and thoughts of characters. These are the details you should mark as relevant information, as discussed in the Annotating chapter.
With a literary narrative, you’ll often see questions that ask what’s going on in a character’s head.
Here’s an example of that kind of question.

So, it’s vital to notice the perceptions, observations, feelings, and thoughts of the characters.
What relevant information should you look for in a literary narrative passage?
The perceptions, observations, feelings, and thoughts of characters
The second passage you’ll see is always the social science passage.
A social science passage is a nonfiction text describing a historical person, event, or place. It’s similar to reading a history book excerpt. That means the relevant information to note is what makes it part of history.
More specifically, you want to take note of the following:
Even though the list above uses the word “character,” the passage may focus on an event or place instead of a person. In that case, you’d still look for the same categories of information (background, accomplishments/impact, and values/beliefs).
Take a look at this example of a social science passage question.

The question above asks about the notable accomplishments of the subject - one of the key things to track in a social science passage.
Question: The social science passage is nonfiction. True or false?
Answer: True, the social science passage is nonfiction. This fits because the social science passage is like a history book.
The third passage you’ll see is always the humanities passage. This passage type is a blend of the first two:
So how do you decide what to focus on?
The key is that a humanities passage will usually behave either like a literary narrative or like a social science passage - and you need to determine which one.
Here’s a simple way to do that:
So, what things should you annotate as relevant information if the humanities passage is in third person?
Basically, things that make history:
What things should you take note of if the humanities passage is in first person?
It’s the “fuzzy” information that’s important in this case:
The fourth and final passage in the reading section is the natural science passage. This passage covers scientific topics like biology, chemistry, or physics. You don’t need outside science knowledge to do well here - the passage will give you the information you need to answer the questions.
The natural science passage is similar to the social science passage in its purpose: it informs you about real-world topics. So, just as you note “what makes history” in a social science passage, you want to note what is important to science in a natural science passage.
What does that mean in practice?
Focus on big-picture ideas. For example, key theories about why the Milky Way has such a definitive warp might be worth annotating if the passage develops them across multiple paragraphs. In contrast, small details mentioned once and never used again (like the fact that the Sagittarius Dwarf Spheroidal Galaxy is about 50,000 light-years from the galactic center of the Milky Way) are less likely to matter.
Other key things to look out for:
Even if the natural science passage seems like paragraph after paragraph of scientific facts, the author is building toward a point.
Often, the author introduces a scientific misconception near the beginning or middle of the passage and then corrects it near the end - using the final paragraphs to prove a larger idea. Those overarching ideas are the ones to annotate as relevant information.
Here’s an example of a question that asks about these overarching ideas.

So to recap, what things are important to mark as relevant information from a natural science passage?
One of the above passages may also appear as a paired passage. It looks something like this:
You’ll see a “Passage A” and a “Passage B,” and your job is to work with two texts and their shared question set.
Paired passages follow a predictable question pattern. They will:
On some paired passage sets, there may be more questions about Passage A than Passage B (or vice versa). The key point is that the questions will still appear in order.
That order matters because it should shape how you approach the paired passage. Here’s what we recommend:
If you had to guess, why do you think we suggest reading only Passage A before starting to answer the questions?
It keeps your stories straight. You don’t want to mix up which passage a question is referring to. Answering Passage A questions is easier when Passage A is the only passage you’ve read so far.
You now know the different passage types you’ll encounter on the ACT Reading section. The ACT can be challenging, but parts of it are very predictable. If you remember the passage order and what each type tends to test, you’ll know what to focus on as you read.
