“It wаs my privilege tо аttend the All Africаn Peоple’s Cоnference held in Ghana. The conference was significant because it brought together the most representative gathering of African leaders ever assembled. There were about 300 delegates representing some 65 organizations coming from 28 African countries. Of the nine independent African countries only one, Sudan, was not represented. The nationalist organizations were represented by their top leadership. Therefore, whether the colonial powers like it or not, the decisions of the conference must be taken with some seriousness. The conference announced clearly that African freedom and independence are a necessity, and that the struggle to achieve independence would continue. The conference’s declaration on colonialism and imperialism significantly called upon ‘the independent African states to render maximum assistance by every means possible to the dependent peoples in their struggle.’ The final decision of the conference was to commend nonviolent methods but also to endorse other methods if they are deemed necessary. Presently, there is negligible Russian influence in Africa. Nevertheless, this influence will grow unless the problem of racism in the multi-racial areas of Africa is solved. It is my opinion that American influence will decline steadily unless the United States is much more vocal in its support of responsible movements for independence in Africa. The United States does not need to be as cautious as it currently is.” George M. Houser, president of the American Committee on Africa, a nongovernmental organization founded to support nonviolent African independence movements, report about the All African People’s Conference held in Ghana, 1958 The conference as described in the first and second paragraphs is best explained in the context of which of the following developments in the aftermath of the Second World War?
“Psychоlоgists оf mаss behаvior might hаve an explanation for what went wrong in China in the late summer of 1958. China was struck with a mass hysteria fed by Mao, who then fell victim himself. Mao began believing the party slogans, casting caution to the winds. As we set out by train heading south from Beijing, the scene along the railroad tracks was incredible. Harvest time was approaching, and the crops were thriving. The fields were crowded with peasants at work. The backyard steel furnaces that had been established in the peasant communes had transformed the rural landscape. They were everywhere, and we could see peasant men in a constant frenzy of activity, transporting fuel and raw materials, keeping the fires stoked. Every commune we visited provided testimony to the abundance of the upcoming harvest. The statistics for both grain and steel production were astounding. Mao’s earlier skepticism had vanished, and common sense had escaped him. The excitement was contagious, and I was infected too. As we continued on our journey, however, Mao’s personal secretary Lin Ke set me straight. What we were seeing from our windows on the train was all staged, he said. The party secretaries had ordered the furnaces constructed along our rail route. Rice plants had been moved from faraway fields along our route so that Mao would see a wildly abundant crop. All of China was a stage, all the people performers in an extravaganza for Mao. The agricultural production figures were false, Lin Ke said, and what was coming out of the backyard furnaces was useless.” Li Zhisui, personal physician to Mao Zedong, biography of Mao, published in the United States, 1994 Which of the following best explains how the historical situation in which Li Zhisui wrote his biography of Mao Zedong influenced Li’s assessment of the experience of the Great Leap Forward?
