Which of the following is a characteristic of examples as context clues?

Examples as context clues often include signal words like "for example" to indicate that what follows is an illustration or specific case that clarifies the preceding idea. This characteristic is essential because it directly links the example to the concept being explained, allowing readers to better understand the author's intent and the specific usage of the term or idea.

By using signal words, the text actively directs readers to look for contextual information that supports understanding. This technique is important in various types of writing, as it not only enriches the text but also aids reader comprehension, particularly when encountering unfamiliar vocabulary or complex ideas.

The other characteristics listed do not accurately represent how examples function as context clues. Descriptive adjectives alone do not define the use of examples, detailed definitions are not guaranteed in every instance of examples, and oppositional context does not apply to the straightforward nature of examples meant to clarify rather than contrast.
