Which option best represents the idea of context clues?

Context clues refer to hints or information provided within a text that assist in determining the meaning of unfamiliar words or phrases. This approach allows readers to infer meanings based on the surrounding words, sentences, or overall context in which a term appears. The correct choice highlights how context clues can help illuminate definitions or clarify meanings without needing external references.

In contrast, the other options do not effectively capture the essence of context clues. Unrelated words do not contribute any meaning or hints about unfamiliar terms. Examples of literary devices focus more on the techniques used by authors rather than providing insight into word meanings. Summaries at the end of paragraphs serve to encapsulate the main ideas of the text rather than offering hints for deciphering specific vocabulary. Thus, the second choice accurately conveys the purpose and function of context clues within writing.
