Final answer:
The intersectionality of ethnicity/race and socioeconomic status is largely responsible for disparities in educational outcomes due to accumulated disadvantages from a person's intersectional identities.
Step-by-step explanation:
According to the text, the intersectionality of ethnicity/race and socioeconomic status largely contributes to disparities in educational outcomes. Disparities in education are not solely due to singular factors, but are often the result of overlapping social identities and issues, including racism, sexism, classism, and more. Feminist sociologist Patricia Hill Collins highlighted that these distinct issues cannot be separated when addressing challenges faced by minority groups. Additionally, there are complex issues within other systems such as the criminal justice system, where discrimination based on race and gender continues to contribute to outcomes like the likelihood of being incarcerated. The accumulation of disadvantages stemming from one's class, race, gender, and other intersectional identities shape the educational opportunities and ultimately the life chances of individuals.
