Which Sentence States The Main Idea Of The Selection? A. A Hydroplane Skims Across The Top Of The Water At Nearly 300 Miles An Hour. B. There Are Many Things Found Around Us That Move At Different Rates. C. The Chimney Swift Has The Fastest Recorded
Introduction
When analyzing a selection of text, it's essential to identify the main idea or central message. This skill is crucial in various fields, including science, where understanding the main idea can help readers grasp complex concepts and relationships. In this article, we'll explore how to identify the main idea of a selection, using a science-related example.
What is the Main Idea?
The main idea, also known as the thesis statement, is a concise summary of the central message or argument presented in a selection of text. It's the key to understanding the author's purpose and the significance of the information presented. In science, the main idea can be a hypothesis, a theory, or a conclusion based on evidence.
Analyzing the Selection
Let's analyze the given selection:
- A hydroplane skims across the top of the water at nearly 300 miles an hour.
- There are many things found around us that move at different rates.
- The chimney swift has the fastest recorded speed of 100 miles per hour.
Identifying the Main Idea
To identify the main idea, we need to look for the sentence that provides the central message or argument. In this selection, the main idea is not explicitly stated in any of the sentences. However, we can infer the main idea by analyzing the content and purpose of each sentence.
- Sentence a describes a specific example of an object moving at a high speed.
- Sentence b provides a general statement about the diversity of speeds found in the natural world.
- Sentence c presents a specific example of an animal moving at a high speed.
Which Sentence States the Main Idea?
Based on the analysis, sentence b "There are many things found around us that move at different rates" is the most likely candidate for the main idea. This sentence provides a general statement that sets the context for the rest of the selection, which presents specific examples of objects and animals moving at different rates.
Why is Sentence b the Main Idea?
Sentence b is the main idea because it:
- Provides a general statement that sets the context for the rest of the selection.
- Introduces the theme of diversity in speeds found in the natural world.
- Allows the reader to understand the significance of the specific examples presented in the selection.
Conclusion
In conclusion, identifying the main idea of a selection is a crucial skill in science and other fields. By analyzing the content and purpose of each sentence, we can infer the main idea and understand the central message or argument presented in the selection. In this example, sentence b "There are many things found around us that move at different rates" is the most likely candidate for the main idea.
Key Takeaways
- The main idea is a concise summary of the central message or argument presented in a selection of text.
- Identifying the main idea requires analyzing the content and purpose of each sentence.
- The main idea can be a hypothesis, a theory, or a conclusion based on evidence.
- In science, the main idea can help readers grasp complex concepts and relationships.
