Answer: A. By locating multiple perspectives in the data
Step-by-step explanation:
The historian must strive for objectivity. If it analyzes statistics and graphs, it is necessary to analyze several different sources. In this way, it is possible to form a clearer picture of a particular event. Statistics and charts may contain inaccurate data. The reason for such a thing may be the subjectivity of the one who provided that information. Subjectivity can arise from various factors, nationalistic, religious, ethnic, and even from more extreme reasons such as racism, fascism, and the like. Historical science is full of such cases, so it is important to be careful and look at each piece of information from several angles.
