Which choice best describes information that provides clear support for the text’s main idea?

The choice that best describes information providing clear support for the text’s main idea is supporting details. Supporting details are specific pieces of information that elaborate on and strengthen the main idea of a text. They can include examples, facts, statistics, anecdotes, and explanations that help readers understand and visualize the main concept being presented.

When a text presents a main idea, it relies on supporting details to effectively convey its message and persuade or inform the reader. These details are essential for a comprehensive understanding and help establish a solid foundation for the arguments or narratives being discussed.

While other options may contain informative elements, they do not specifically focus on reinforcing the main idea as strongly as supporting details do. Background information provides context but may not directly relate to the main idea. Confirmatory facts can validate an argument but may not always elaborate or explain it. Research data offers empirical evidence, which is valuable, but it’s the supportive details that directly connect back to and underpin the main idea in a more applicable way.
