The correct answer is D. Stories about the experience of being unemployed
Step-by-step explanation:
When trying to understand a certain event or phenomenon there are different ways to approach the event and get the information. In the case of the economic historian this historian tries to understand the Great depression by using a chart and probably numbers and statistic which is a type of quantitative data that allows historians to understand events as they occurred, this means in this case the historian can know the rate of unemployment in each state or city and the way this changed. On the other hand, the cultural historian aims at understanding data from a qualitative approach or from the experiences of people and because of this, this historian uses interviews.
This means the type of information the cultural historian would have and not the economic historian is "stories about the experience of being unemployed" because this is qualitative data and can be gathered through interviews, but never through the statistics, numbers, and chart used by the economic historian.
