Question

A topic sentence
A summary
Supporting details
The central idea

Answer 1

An introduction in a single paragraph can take the form of a topic sentence that presents the central idea, followed by supporting details that provide context, background, or rationale for the topic. This structure effectively sets up the reader for the main points that will be discussed in the body of the text. Therefore, a well-crafted single-paragraph introduction typically includes a clear topic sentence that outlines the central idea, along with concise supporting details to engage the reader.
