What are common text features found in informational texts?

The correct answer highlights common text features typically found in informational texts, which serve specific purposes in conveying information to the reader effectively. Headings and subheadings help organize content and guide readers through different sections, making it easier to find relevant information. Captions provide context for images or graphs, enhancing understanding of the visual elements. Graphs can illustrate data, trends, or relationships in a more digestible format than text alone. An index allows for quick reference, enabling readers to locate specific topics or terms within the text.

These features are particularly important in informational texts as they assist in clarifying complex information and improving overall comprehension, which is essential for readers seeking to acquire knowledge on a particular subject. Other answer options refer to literary devices and elements more often used in narrative texts rather than the structured and fact-based nature of informational writing.
