D. Concrete details

The option that includes specific and observable ideas in an informative text is "D. Concrete details."

To identify concrete details in a text, you can follow these steps:

1. Read the text: Start by thoroughly reading the informative text you are analyzing.

2. Look for specific information: Look for sentences or phrases that provide specific and factual information. Concrete details are usually observable and can be measured or verified. They answer questions like "who," "what," "when," "where," and "how."

3. Pay attention to descriptive language: Concrete details often include vivid and precise descriptions of people, places, actions, or objects. Look for words or phrases that create a clear mental image.

4. Analyze examples and evidence: Concrete details can also include examples, statistics, or other types of evidence that support the main idea or central argument of the text.

5. Eliminate other options: Once you have identified the concrete details in the text, eliminate the other options (such as the main idea, city sources, and introduction) as they may not necessarily provide specific and observable ideas.

By following these steps, you can successfully identify the concrete details in an informative text and determine which option corresponds to it.
