What should you listen for when identifying supporting details in a passage?

When identifying supporting details in a passage, it is essential to focus on examples, explanations, and elaborations, as these elements provide the necessary context and reinforcement for the main idea. Supporting details help clarify the topic and enhance understanding by illustrating points made or providing necessary background. By listening carefully for these components, you are able to gather information that backs up the main argument or claim presented in the passage. This approach hones in on specifics that lend credibility and depth to the broader narrative or thesis, making them critical for comprehension and retention of the material.

The other options highlight aspects that do not focus on the core elements of supporting details. The main idea, while important, is not sufficient alone to understand the nuances of the passage. Summaries at the end can provide a recap but do not offer the depth of information contained in examples or explanations throughout the text. Similarly, personal opinions of the speaker may provide insight into their perspective, but they do not inherently serve as supporting details that substantiate the main idea. Therefore, the emphasis on examples, explanations, and elaborations makes option B the most relevant choice for identifying supporting details.
