Answer :
To determine the central idea of a text, the element that best helps the reader is the **paragraph structure**.
Here's why:
1. **Organization**: Paragraph structure involves how the ideas are grouped and presented in the text. The main idea is often introduced in the topic sentence of a paragraph and supported by details and examples in the following sentences.
2. **Transitions**: Transition words and phrases within paragraphs help connect ideas and guide the reader through the text. They can signal relationships between different pieces of information, helping to uncover the central idea.
3. **Development**: The way paragraphs develop and expand on the central idea provides a roadmap for understanding the main message or argument of the text. Paying attention to how ideas progress within and between paragraphs can lead to a better grasp of the central theme.
By analyzing the paragraph structure, readers can identify recurring themes, key arguments, and the overall message the author is trying to convey, which in turn helps in determining the central idea of the text.
