Final answer:
Nelson Mandela expected global support to end apartheid, which is shown by the international impact of economic sanctions and boycotts, as well as the ANC's strategic actions which corresponded with a broad international recognition and support of their cause.
Step-by-step explanation:
Of the provided passages, the one that best supports the claim that Nelson Mandela expected support from around the world centers on the global campaign against apartheid and the influence of economic sanctions and international condemnation. While no direct quotation from Mandela about expecting global support, the international impact is implicit in the context that Mandela's leadership and the actions taken by the African National Congress (ANC) were part of the broader struggle recognized and supported internationally.
In particular, the passage mentioning that "by the 1980s, continued opposition to apartheid, economic sanctions imposed by foreign countries, boycotts of South African businesses, and international condemnation had begun to have an effect" suggests that Mandela's strategy involved generating external pressure to aid internal change. Additionally, the divestment movement's threat to the South African economy and the eventual lifting of the ban on the ANC operate as examples of how Mandela's foresight and expectation for worldwide support played a substantial role in the country's journey to democracy.
