Identifying Main Idea & Supporting Details
Understanding the Concept of Main Idea and Its Location in a Passage
The main idea is the central message or overarching point that an author wants to convey in a passage. It represents the essence of what the passage is about. Think of it as the foundation upon which the entire passage is built.
The main idea can be explicitly stated by the author, often found in:
- The Introduction: The opening paragraph frequently introduces the topic and may even contain a thesis statement that directly expresses the main idea.
- The Topic Sentence: Each paragraph typically has a topic sentence that introduces the main point of that particular paragraph. While not all passages will have explicit topic sentences, they are a valuable clue when present.
- The Conclusion: The final paragraph often summarizes the key points or restates the main idea in a concluding statement.
However, the main idea is not always explicitly stated. In some cases, the author may imply the main idea through the supporting details. This requires the reader to actively engage with the passage and draw their own conclusions.
Recognizing Supporting Details that Reinforce the Main Idea
Supporting details are facts, examples, statistics, anecdotes, or explanations that elaborate on and strengthen the main idea. They provide evidence to back up the author’s central point.
Here’s how to identify supporting details:
- Relevance: Supporting details are directly related to the main idea. Ask yourself, “Does this detail explain or add to the central point?”
- Location: Supporting details can be found throughout the passage, but they often appear in the same paragraph as the main idea they support.
Identifying Different Ways Authors Express the Main Idea
Authors express the main idea in various ways, making it crucial to be flexible in your approach. Here are some common methods:
- Direct Statement: The author explicitly states the main idea in a sentence. For example, “The benefits of regular exercise are numerous and well-documented.”
- Inference: The main idea is implied but not directly stated. The reader must analyze the supporting details and draw their own conclusions. For example, a passage may discuss the importance of healthy eating habits, listing various benefits like improved energy levels and weight management. The implied main idea might be that “healthy eating habits contribute to overall well-being.”
- Emphasis: Authors may use techniques like repetition, bolding, italics, or figurative language to highlight the main idea.

Passage 2:
Honey: A Natural Sweetener
Honey has been used as a sweetener and natural remedy for centuries. Honey is produced by bees as they collect nectar from flowers. This nectar is then transformed into honey through an enzymatic process. Honey contains a variety of beneficial nutrients, including antioxidants, vitamins, and minerals. These nutrients contribute to honey’s potential health benefits, such as wound healing and soothing sore throats. While honey offers some advantages over refined sugar, it is still a source of calories and should be consumed in moderation.
Questions:
- What is the main idea of the passage?
- Answer: Honey is a natural sweetener with potential health benefits.
- Identify two supporting details from the passage.
- Answer: (a) Honey contains a variety of beneficial nutrients, including antioxidants, vitamins, and minerals. (b) Honey offers potential health benefits such as wound healing and soothing sore throats.
Additional Tips:
- Pay attention to signal words that often introduce supporting details, such as “for example,” “in addition,” “because,” and “furthermore.”
- When faced with a difficult passage, don’t get bogged down in the details. Focus on identifying the overall message the author is trying to convey.
Advanced Strategies for Identifying Main Ideas
While the basic principles of identifying main ideas and supporting details apply to most passages, some require a more nuanced approach. Here are some additional strategies to consider:
- Distinguishing Between Main Idea and Supporting Ideas: Not all ideas presented in a passage are equally important. The main idea is the most significant concept, while supporting ideas provide details or elaboration. Look for the idea that encompasses the other points discussed.
- Identifying Multiple Main Ideas: In some cases, a passage may present two or more main ideas, particularly in longer or more complex texts. Often, these main ideas will be presented in separate paragraphs with their own supporting details.
- Evaluating the Importance of Information: Not all details within a paragraph are equally relevant to the main idea. Some details may be more peripheral or serve as background information. Focus on the details that directly contribute to understanding the central point.
- Considering the Author’s Purpose: Understanding the author’s purpose for writing the passage can provide valuable clues about the main idea. Are they trying to inform, persuade, entertain, or argue a point? The author’s purpose will often shape the content and emphasis of the main idea.
- Watch Out for Distractions: Authors may sometimes include irrelevant information or tangential details to support a specific agenda or create a particular tone. Don’t be misled by these distractions and stay focused on identifying the central message.

Passage 3:
The Rise of Telemedicine
Telemedicine, the use of telecommunications technology to provide healthcare services remotely, has grown significantly in recent years. This growth is driven by several factors, including advancements in technology, increasing patient demand for convenience, and a growing shortage of healthcare professionals in rural areas. Telemedicine offers a range of benefits for both patients and providers. Patients can access healthcare services from the comfort of their homes, reducing travel time and wait times in clinics. Providers can expand their reach and offer services to geographically dispersed populations. However, telemedicine also presents some challenges, such as the need for reliable internet access and potential limitations in conducting thorough physical examinations. Overall, telemedicine represents a promising innovation with the potential to improve access to healthcare and enhance patient care.
Questions:
- What is the main idea of the passage?
- Answer: Telemedicine is a growing trend in healthcare offering benefits for both patients and providers, despite some challenges.
- Identify two main ideas from the passage. (Consider the presence of multiple main ideas)
- Answer: (a) Telemedicine has grown significantly due to advancements in technology, patient demand for convenience, and healthcare professional shortages. (b) Telemedicine offers advantages for patients (convenience, reduced wait times) and providers (expanded reach, serving geographically dispersed populations).
Passage 4:
Organic Farming: A Sustainable Approach
Organic farming practices aim to produce food without the use of synthetic fertilizers, pesticides, or genetically modified organisms (GMOs). Proponents of organic farming cite several benefits, including environmental protection, improved soil health, and potentially healthier food options. Organic farming practices can help reduce pollution from agricultural runoff and promote biodiversity. However, organic farming can also be less efficient in terms of crop yield, leading to higher prices for consumers. Additionally, the term “organic” can be subject to some ambiguity, and regulations surrounding organic certification can vary. Despite these challenges, organic farming represents a viable approach to sustainable food production.
Questions:
- What is the main idea of the passage?
- Answer: Organic farming offers environmental and potential health benefits but comes with challenges like lower yields and ambiguous regulations.
- Identify the author’s purpose for writing the passage. Does the author advocate for or against organic farming?
- Answer: The author’s purpose is likely to inform readers about organic farming, presenting both its benefits and challenges. The passage doesn’t explicitly advocate for or against it.
Remember: Mastering the skill of identifying main ideas and supporting details is crucial for success in the HESI A2 Reading Comprehension section. By employing the strategies outlined above and practicing with a variety of passages, you can develop the critical thinking skills necessary to excel on the test and become a more proficient reader overall.
