When using a graphic or chart in a presentation, especially one based on statistical data, it's important to properly cite the source of the information. Citing sources not only gives credit to the original publisher but also allows your audience to verify the information and ensure its credibility.
Given the available choices:
1. Its publisher and date of publication
2. Khaled's full name and grade in school
3. Several sentences describing the chart
4. A photo to help illustrate the chart
While adding descriptive sentences or photos can enhance the presentation, the most crucial piece of information that must be included with the graphic is its publisher and date of publication. This information ensures that the data can be traced back to its original source, establishing reliability and helping to avoid plagiarism.
In summary, for Khaled to properly use the chart in his presentation on climate change, he must include the graphic's publisher and date of publication. This ensures the information is appropriately credited and verifiable.
