Understanding how to locate information quickly in nonfiction relies on a built-in reference that organizes terms for fast lookup. A glossary does exactly that: it lists terms in alphabetical order along with their definitions, so you can flip to the term and read its meaning without paging through the entire book. This makes it the quickest way to understand unfamiliar vocabulary and key terms, helping you navigate the text more efficiently. The other options aren’t designed for quick reference: a prologue introduces the work, a narrative tells a story, and a metaphor is a figure of speech used for meaning, not for finding specific information.

Repeated reading builds fluency by having students read the same passage several times while the teacher provides feedback to improve accuracy, pace, and expression. With each reading, students become more automatic and confident readers, and the teacher’s suggestions after or during the readings help guide improvements in pronunciation, phrasing, and prosody. Echo reading centers on the teacher modeling and the student echoing what is read, which is more about imitation than repeated independent practice with targeted feedback. Paired reading uses a partner to share the reading task, offering support but not the same teacher-guided, multiple-read sequence. Differentiation strategies refer to tailoring instruction to individual needs and can include various methods, not this specific repeated-reading routine with teacher feedback.

Literal comprehension is understanding exactly what the text states on the surface—the facts, details, and the central point as it’s written. Identifying the main idea fits this because it asks you to pick the central point the author is presenting based on what is clearly stated or directly supported by the text. This is about surface meaning, not about guessing beyond what’s written. Predicting what happens next requires using clues to imagine future events, which goes beyond literal facts and into predicting. Inferring the author’s purpose involves reading between the lines to uncover motives, which is inference. Evaluating the text’s credibility involves judging trustworthiness and reliability, which is analytical thinking about the text. So identifying the main idea is the best match for literal comprehension since it focuses on the explicit, stated content.

The main idea of a paragraph is set up by the topic sentence. It tells the reader what this paragraph is about and what idea will be explored. By stating the focus right away, the writer gives clear direction, and the reader can follow how the rest of the sentences will develop that idea. The following sentences then add details, examples, and explanations that support this main point. A concluding sentence would wrap things up or connect to the next paragraph, not introduce the main idea. Likewise, bringing in a new theme belongs to a different paragraph. For example, if the paragraph is about how daily exercise improves mood, the topic sentence would state that idea, and the rest of the sentences would back it up with evidence and details.
