In your response, consider the varying perspectives presented in the following sources: Source 1. Statistical Data from "The Growing Diversity of Black America" by Pew Research Center, 2021. The first is a bar chart with columns representing the years 2000, 2006, 2010, 2015, and 2019. The bottom portions are maroon red, representing Bachelor’s degree. The top portions are yellow, representing Master’s degree. Statistics read as follows: in 2000, 10 percent had a Bachelor’s and 5 percent had a Master’s for a total of 15 percent. In 2006, 11 percent had a Bachelor’s and 6 percent had a Master’s for a total of 17 percent. In 2010, 12 percent had a Bachelor’s and 6 percent had a Master’s for a total of 18 percent. In 2015, 13 percent had a Bachelor’s and 8 percent a Master’s for a total of 21 percent. And in 2019, 14 percent had a Bachelor’s and 9 percent had a Master’s for a total of 23 percent. The second line chart uses the same colors and same time frame, but also gives approximate numbers in millions. The lower, yellow line represents 1 million with a Master’s in 2000, 1.3 million in 2006, 1.6 million in 2010, 2 million in 2015, and 2.6 million in 2019. The upper, red line represents 2 million with a Bachelor’s in 2000, 2.5 million in 2006, 2.9 million in 2010, 3.5 million in 2015, and 4.1 million in 2019. "The Growing Diversity of Black America."

"Breakdancers in New York," 1984 On the cardboard, the dancer curves his back deeply as he kicks his feet apart, high in the air. His other hand is at the small of his back. He wears jeans, a white headband and wristbands, and a white hoodie under a black leather jacket. The four men posing behind him all wear track suits with matching pants and jackets. Two are blue, one is gray, and the fourth is red. Three of the men stand and wear white gloves on both hands. Two lean back on one foot and thrust their hands toward the camera, while the fourth stands on both feet and gives the rock-and-roll sign with the pointer and pinky fingers raised. The fourth man, to the right, crouches and watches the dancer. All five men wear white sneakers with a black Nike swoosh along the side. The wall behind them is layered with colorful graffiti.

Playbill for Fences by August Wilson, 1987 In grayscale, a white man to the left of the F stands hands on hips, and an African American man stands with his arms by his sides to the right of the S. The white man wears a snap-brim cap, a collared shirt, and slacks. The Black man wears a football uniform, and they look across the word at each other.

Colin Powell's Howard University Commencement Address, 1994 "Education is the key to success in life, and teachers make a lasting impact in the lives of their students. Twenty-seven years ago, I was you, sitting where you sit now, dreaming big dreams. Today, I return as Chairman of the Joint Chiefs of Staff. That journey was possible because of education, determination, and the values instilled in me by my immigrant parents and the opportunities provided by this great democracy of ours. But remember this, success is not an entitlement. Each new generation must work for it, earn it, build on what came before. My success was built on the sacrifices and struggles of earlier generations of African Americans who fought to open doors that were once firmly closed. Your challenge is to use your education to open still other doors, to give others the opportunity to stand on your shoulders, just as you stand on the shoulders of those who went before."
