Final answer:
African Americans were pushed from the South by discrimination and disenfranchising laws and pulled to the North by the prospect of economic opportunity and more tolerant communities during the Great Migration of the 1920s.
Therefore, the correct answer is: option "Pull Factors The North had more tolerant communities".
Step-by-step explanation:
The northern migration of African Americans in the 1920s was influenced by a variety of push and pull factors. Factors such as rampant discrimination socially and economically, poll taxes, and literacy tests that disenfranchised many African Americans were significant push factors driving them away from the South.
Conversely, the North offered several pull factors which included more tolerant communities, opportunities for a steady income provided by industrial jobs in factories, and the absence of legally enforced segregation.
Contextually, the Great Migration was a pivotal event in American history. The North's offer of better schools, higher wages regardless of still prevalent discrimination, and a promise of greater personal freedoms acted as substantial pull factors. This migration reflected both a flight from oppressive conditions in the South and an attraction to the economic and social opportunities in the urban North.
