Final answer:
WEB Du Bois encouraged black female writers, artists, poets, and novelists during the Harlem Renaissance, resulting in increased representation of diverse voices in literature and art, and the introduction of new artistic movements in African American communities.
Step-by-step explanation:
The impact of WEB Du Bois encouraging black female writers, artists, poets, and novelists during the Harlem Renaissance was significant on the cultural landscape at that time. It resulted in increased representation of diverse voices in literature and art, as African American women were given a platform to express their experiences and perspectives. It also contributed to the introduction of new artistic movements in African American communities, as these writers and artists brought forth unique styles and themes that challenged the prevailing stereotypes. However, it did not directly lead to the establishment of gender equality among black intellectuals or the emergence of new educational institutions for black women.
