Final answer:
Ken should cover the work of bell hooks, Sudanese painter Ibrahim El-Salahi, Ethiopian multimedia artist Skunder Boghossian, and contemporary artists of the African diaspora who have depicted the troubles of racial and gender stereotypes in their work.
Step-by-step explanation:
In his speech about artists who depicted the troubles of racial and gender stereotypes, Ken should cover the work of bell hooks, a postmodern author who has addressed the intersection of race, class, and gender in education, art, history, and feminism. He should also discuss the work of Sudanese painter Ibrahim El-Salahi and Ethiopian multimedia artist Skunder Boghossian, who have made art inspired by their heritage and national identity, drawing attention to Pan-Africanism and postcolonial movements through their visual arts.
Additionally, contemporary artists of the African diaspora including Beyoncé, Awol Erizku, Zeft, Fred Wilson, and Umar Rashid have reclaimed and repopularized famous and iconic images of Nefertiti and other well-known Egyptian art, forcefully reclaiming and returning it back into the art historical canon of the African diaspora.
