Learn to identify a passage’s main idea, select details that support it, and explain how evidence connects to the central point.
Main ideas and
A is the most important point a passage makes about its topic. help readers understand or believe that point; they can be facts, reasons, examples, or explanations. A detail is relevant when it connects clearly to the , not merely because it appears in the same passage.

Use this process to find details that support a passage’s central point:
Identify the topic. Ask what person, place, event, or subject the passage is about.
State the . Identify the important point the author makes about the topic, and put it in your own words.
Look for . Find details that explain, prove, or illustrate the .
Check the connection. Ask how each detail helps you understand the . If you cannot explain the connection, the detail may be unrelated or less important.
For example, a passage about a school garden says that it can help students learn science. Students observe and record how seedlings change over time, and compare plant growth in sunny and shady places. It also mentions that the garden has three wooden benches painted blue last spring.
The topic is the school garden, and the is that the garden helps students learn science. The observations and comparisons are major because they show how the garden teaches science. The benches’ color and the time they were painted are minor information in this context: they do not support the about science learning.
Judge the importance of details
A directly develops an important part of the . It may give a key reason, explain a process, or provide a central example. A adds a small fact or extra description and usually is not needed to explain the passage’s central point.
Whether a detail is important depends on the and the question being asked. The bench detail is minor when the passage is about science learning, but it could be important if the question asks what color the benches are. Do not classify a detail as minor just because it is short or includes a number; judge what it contributes.
Explain how supports an idea
A detail is stronger support when you can explain how it connects to the . Use this frame:
The is ____. The detail ____ supports it because ____.
For the garden example: “The is that the garden helps students learn science. The detail about comparing plants in sunny and shady places supports it because students are making observations about growing conditions.”
When answering a question, use the passage’s rather than relying only on what you already know. Name a and explain what it shows. If more than one detail supports the , choose the clearest or most important ones. Identifying key ideas and , then summarizing the main points, are core reading-comprehension practices.
make a passage’s clearer. Find the first, select details that directly explain or demonstrate it, and explain how each detail connects. Leave out extra information unless the question specifically asks for it.
