Let’s delve deeper into what you need to know to conquer this section of the ACT Reading test.

Essential Concepts to Master for Key Ideas & Details

1. Central Ideas and Themes

Central ideas and themes are the recurring concepts or messages in a text. These are the big ideas that the author wants you to take away from the passage. Identifying these central ideas is critical because they often form the basis of multiple questions within the reading section.

How to Identify Central Ideas and Themes:

Look at Topic Sentences: The topic sentence of each paragraph often hints at the central idea of that paragraph. By paying close attention to these sentences, you can piece together the overall theme of the passage.

Jot Down Key Points: As you read, jot down a few words or a brief summary for each paragraph. This will help you remember the key ideas and see how they connect to form the central theme.

Consider Repeated Ideas: If an idea or concept is mentioned multiple times throughout the passage, it’s likely central to the author’s message.

2. Summarizing Information

Being able to summarize information accurately is another critical skill for Key Ideas & Details questions. Summarization involves condensing the passage’s information into your own words while retaining the core message.

Strategies for Summarizing:

Locate the Reference: Find the exact part of the passage the question refers to. Read the surrounding sentences to understand the context.

Paraphrase the Information: Before looking at the answer choices, try to summarize the information in your own words. This will help you process the text and ensure you’ve understood it correctly.

Match Your Summary to the Answer Choices: Choose the answer choice that best aligns with your summary. Make sure every part of the answer choice is supported by the text.

3. Understanding Relationships

Understanding relationships within a text is crucial for Key Ideas & Details questions. This includes recognizing sequential, comparative, and cause-effect relationships.

Identifying Different Types of Relationships:

Sequential Relationships: These are often indicated by transition words like “first,” “second,” “then,” and “finally.” The structure of the passage may follow a chronological order, making it easier to track the sequence of events.

Comparative Relationships: Look for similarities and differences between two ideas or concepts. Keywords like “similarly,” “on the other hand,” and “in contrast” can help you spot these relationships.

Cause-Effect Relationships: These relationships explain why something happened (the cause) and what happened as a result (the effect). Look for phrases like “because of,” “led to,” “resulted in,” or “due to” to identify cause-effect relationships in the text.

What Do Key Ideas & Details Questions Look Like?

Understanding what Key Ideas & Details questions look like can help you prepare for them more effectively. These questions often come in two forms: Main Idea Questions and Detail Questions.

Main Idea Questions

Main idea questions focus on the overall purpose or central theme of the passage. They often look like this:

“The main purpose of the passage is…”

“One central idea of this passage is…”

“One claim heavily supported by this passage is…”

“The purpose of paragraph 3 (lines 21-28) is…”

How to Approach Main Idea Questions:

Identify the Main Ideas as You Read: Write down a few words (around 5 words) about each paragraph’s main idea as you read it. This exercise forces you to think critically about the passage and identify the key ideas.

Match Your Notes with Answer Choices: Once you have identified the main ideas, match them with the answer choices. This ensures that your answer is backed by textual evidence.

Detail Questions

Detail questions require you to go back to the text and find specific information. These questions might look like:

“According to the passage, the reason for Natalie to avoid her grandmother’s tea parties was…”

“According to the passage, Goldilocks did not prefer the mother’s porridge because…”

How to Approach Detail Questions:

Locate the Specific Text: Find the exact part of the passage that the question refers to. This might involve skimming the passage again or using your notes to pinpoint where the information is located.

Read the Surrounding Context: Once you’ve found the relevant part of the text, read a few sentences before and after to understand the context.

Rephrase the Information: Paraphrase the information in your own words to ensure you’ve understood it correctly. Then, match it to the answer choices and select the one that most closely aligns with your understanding.

Practical Examples of Key Ideas & Details Questions

Let’s look at some practical examples to illustrate how to tackle Key Ideas & Details questions.

Example 1: Main Idea Question

Consider the following passage:

“The Men of Brewster Place”
Clifford Jackson, or Abshu, as he preferred to be known in the streets, had committed himself several years ago to use his talents as a playwright to broaden the horizons for the young, gifted, and black—which was how he saw every child milling around that dark street. As head of the community center he went after every existing grant on the city and state level to bring them puppet shows with the message to avoid drugs and stay in school; and plays in the park such as actors rapping their way through Shakespeare’s A Midsummer Night’s Dream. Abshu believed there was something in Shakespeare for everyone, even the young of Brewster Place, and if he broadened their horizons just a little bit, there might be enough room for some of them to slip through and see what the world had waiting. No, it would not be a perfect world, but definitely one with more room than they had now.*

Sample Question: What did Abshu dream of doing?

Answer Strategy:
Start by analyzing the specific part of the text the question refers to: “Clifford Jackson, or Abshu…had committed himself several years ago to use his talents as a playwright to broaden the horizons for the young, gifted, and black.” This sentence tells us that Abshu’s dream was to use his talents to broaden the horizons of the children around him.

Summary:
Abshu, as a playwright, wanted to broaden the horizons of the children in his community. This understanding should help you identify the correct answer, which aligns with the idea that Abshu wanted to inspire and empower the children through the arts.

Example 2: Detail Question

Now, consider another passage:

“You cannot see any of this. But Dr. Harry Chugani can come close. With positron-emission tomography (PET), Chugani, a pediatric neurobiologist, watches the regions of a baby’s brain turn on, one after another, like city neighborhoods having their electricity restored after a blackout. He can measure activity in the primitive brain stem and sensory cortex from the moment the baby is born. He can observe the visual cortex burn with activity in the second and third months of life. He can see the frontal cortex light up at 6 to 8 months. He can see, in other words, that the brain of a baby is still forming long after the child has left the womb—not merely growing bigger, but forming the microscopic connections responsible for feeling, learning, and remembering.”

Sample Question: According to the passage, what does PET allow Dr. Chugani to observe?

Answer Strategy:
To answer this, locate where PET is discussed in the passage. The text mentions that PET allows Dr. Chugani to observe the regions of a baby’s brain turning on, including the primitive brain stem, sensory cortex, visual cortex, and frontal cortex.

Summary:

PET scans show regions of a baby’s brain becoming active over time, including the primitive brain stem, sensory cortex, visual cortex, and frontal cortex. This understanding will guide you to the correct answer, which should reflect the ability of PET to observe these brain activities.
