Which purpose does a relevant detail serve?

1. It evaluates facts and evidence
2. It identifies ideas not related to the topic
3. It undermines the effectiveness of an argument
4. It supports the central idea of the text

4. It supports the central idea of the text

The purpose of a relevant detail is to support the central idea of the text (option 4).

To determine the purpose of a relevant detail, you can follow these steps:

1. Identify the central idea of the text: Read the entire text and focus on the main point or message that the author is trying to convey.

2. Find the supporting details: Look for specific pieces of information or evidence that support or elaborate on the central idea. These details should be directly related to the main point and help to strengthen and clarify it.

3. Evaluate the role of the relevant detail: Determine how each detail contributes to the overall argument or message. A relevant detail will directly support the central idea without introducing unrelated ideas (option 2), undermining the effectiveness of the argument (option 3), or evaluating facts and evidence (option 1).

By analyzing the relationship between the central idea and the supporting details, you can determine the purpose of a relevant detail in a text.
