To appropriately use the information from the chart in his presentation on climate change, Khaled needs to establish the credibility and context for the statistics presented. This means that he should look at the following essential piece of information that must be included with the graphic:
- Its publisher and date of publication
Here’s the reasoning behind this choice:
1. Credibility: Including the publisher’s name helps verify the authenticity of the chart. It provides evidence that the data came from a reputable source, which is crucial for any statistical claim.
2. Context: The date of publication is critical as it informs the audience about the time period the data covers. Since data can change over time, knowing when the data was published helps in understanding its relevance to the current situation.
The other options provided—Khaled's full name and grade in school, several sentences describing the chart, or a photo to help illustrate the chart—do not contribute to the authenticity or validity of the data presented in the chart. They may add supplemental information or visual aid, but they do not ensure the reliability of the data itself. Therefore, the correct choice is to include the publisher and date of publication with the graphic.
