A historian is collecting sources for a paper about the impact of industrialization in the United States during the early 1900s. She has determined that all of the sources she has collected are relevant to the topic, but is worried that some may not be credible.

Select two sources the historian can use because they are credible.

• a transcript of eye-witness trial testimony following a New York City factory fire in 1911

a data set from the Census Bureau detailing changes to urban and rural populations between 1900 and 1911

a newspaper editorial from a factory owner that contradicts primary records and documents from the early 1900s

a fictional novel about challenges facing a group of female factory workers in Philadelphia during the early 1900s

a research article without supporting evidence that describes working conditions in factories during the early 1900s

The two sources that the historian can use because they are credible are:

- a data set from the Census Bureau detailing changes to urban and rural populations between 1900 and 1911: Census data is typically considered a reliable and credible source for demographic information, providing concrete numbers and trends that can be analyzed and interpreted.

- a transcript of eye-witness trial testimony following a New York City factory fire in 1911: Eye-witness testimony from a trial related to industrialization can provide direct and firsthand accounts of the impact of industrialization on individuals and communities during that time period. This type of primary source material can offer valuable insights and perspectives on the topic.
