Final answer:
Marshall’s second study highlighted the lack of diversity and the prevalence of stereotyping in film, emphasizing the harm to society and ending with a call for change.
Step-by-step explanation:
Marshall (2008) conducted a second study that analyzed the representation of diversity, or lack thereof, in film and television. In her evidence, Marshall utilized specific examples and quotations from primary sources to emphasize the prevalence of stereotyping and the exclusion of Black characters in film. This was further illustrated by a detailed example. By conducting a comparison to other films, she broadened her study to indicate how this was a widespread issue. Eventually, Marshall concluded her study by echoing her thesis on the damaging effects of lacking diversity on society and ended with a proposition for change, citing a quotation from a secondary source that acted as a call to action.
