To properly use the reliable chart in his presentation, Khaled should include information that provides context and credibility. This ensures that the audience can understand the origin and validity of the data presented. Among the options given:
1. Khaled's full name and grade in school
2. Several sentences describing the chart
3. A photo to help illustrate the chart
4. Its publisher and date of publication
Including Khaled's name and grade, or sentences describing the chart, or a photo can be helpful, but they are more supplementary in nature. The most critical piece of information that must be included is the publisher and the date of publication. This addition allows the audience to verify the data and assess its reliability and timeliness.
Therefore, the necessary information that must be included with the graphic is its publisher and date of publication.
