The inference best supported by the passage is that the roles and jobs given to Africans in South Africa promote dehumanization, aligning with option C of the provided choices.
To infer the most supported notion of "black inferiority" from the passage provided, option C, which states that the roles and jobs given to Africans further promote dehumanization, aligns best with the passage. The text describes a systemic undervaluing of Africans reinforced by a culture of white supremacy that entrusts menial tasks to black individuals and negates their humanity and familial bonds. This institutionalized viewpoint perpetuates the prejudice that blacks are naturally suited for lower status, perpetuating their socio-economic disenfranchisement and rendering the concept of racial equality unattainable. The passage discusses the policy of white supremacy and its implications for Africans. The author argues that white supremacy reinforces the notion of black inferiority by relegating Africans to menial tasks and treating them as a separate breed. Therefore, the inference that is best supported by the passage is that the roles and jobs given to Africans further promote dehumanization.
