Which of the following describes how an example can illustrate a general rule?

The correct answer illustrates how specific examples can illuminate broader concepts or general rules. An example serves as a tangible manifestation of a rule, showcasing particular characteristics that align with the overarching principle. This connection between the example and the general rule allows readers to better understand the concept by relating it to something concrete and familiar. For instance, if a general rule states that exercise improves health, citing a specific example of a person who became healthier after a consistent workout routine helps reinforce and clarify that rule.

The other options do not effectively demonstrate this relationship. One option suggests that a singular case lacks broader relevance, which fails to connect the example to the general rule. Another option implies that practical instances merely simplify complex theories without revealing any alignment, which undermines the purpose of providing examples. The final option describes an isolated phenomenon rather than linking it to broader concepts, which diminishes the value of using an example to illustrate a general rule.
