When Khaled presents a graphic in his presentation on climate change, it is crucial to include certain pieces of information to ensure the graphic's credibility and reliability. These pieces of information validate the source and context of the data shown.
In this scenario, let's analyze the importance of the given options and identify which one is essential to include with the graphic:
1. Its publisher and date of publication:
- Including the publisher and date of publication provides the audience with the source of the information and the timeframe when the data was collected or published. This is crucial for verifying the data's reliability and relevance.
2. Khaled's full name and grade in school:
- While Khaled's name and grade provide context about the presenter, it does not contribute to the credibility of the graphic itself. The focus should be on the origin and validity of the data.
3. Several sentences describing the chart:
- Descriptions can help explain the context and findings of the chart. However, this information is more about interpretation rather than validating the source of the statistics. Descriptions are useful but not as essential as knowing the source.
4. A photo to help illustrate the chart:
- Illustrative photos can enhance the visual appeal and help make the data more engaging. They are supplementary and not necessary for validating the data's authenticity.
Given these points, the piece of information that must be included with the graphic is its publisher and date of publication. This information is critical to ensure that the audience can trust the accuracy and current relevance of the statistics presented in the chart.
