You're right in looking to enrich a graphic with essential information. When including a chart in a presentation, it's critical to provide sufficient context so the audience can understand the source and the reliability of the data. Out of the options given:
- The publisher and date of publication: This is crucial because it provides the source of the data, which allows the audience to assess its credibility and understand its timeliness.
- Khaled's full name and grade in school: While this might be relevant in a certain educational context, it does not add to the understanding or credibility of the data within a general presentation on climate change.
- Several sentences describing the chart: Providing a description can help viewers understand what the chart shows and highlight key points. However, this is not a replacement for citing the source.
- A photo to help illustrate the chart: While visuals can add to the engagement and help illustrate the topic, they do not provide information about the origin or reliability of the data.
The most essential piece of information that must be included with the graphic would be its publisher and date of publication, as this ensures that the audience can reference the data and understand its context and reliability.
