To determine which piece of information must be included with the graphic, let's consider the importance of each option.
1. Publisher and date of publication: This is crucial for verifying the reliability and recency of the information. It allows the audience to trust the source and provides context for when the data was collected.
2. Khaled's full name and grade in school: While this might be relevant in a school setting to identify the presenter, it does not add to the authenticity or credibility of the data itself.
3. Several sentences describing the chart: This can be beneficial for explaining the data but is not absolutely essential for the chart's integrity. It would be more of a supplementary addition.
4. A photo to help illustrate the chart: Including a photo can make the presentation more engaging but is not mandatory for understanding the chart data.
Considering these options, the most essential piece of information that must be included with the graphic to ensure its credibility and proper context is its publisher and date of publication.
