A. Exporting oil to Israel,
Because, during the 1973 Arab-Israeli War, Arab members of the Organization of Petroleum Exporting Countries (OPEC) imposed an embargo against the United States in retaliation for the U.S. decision to re-supply the Israeli military and to gain leverage in the post-war peace negotiations.
I'm not sure though
Explanation:
In Africa, failure to address housing issues has led to the continued growth of slums and poorly serviced informal settlements on the urban periphery, where between 75% and 99% of urban residents in many African cities live in squalid slums of ramshackle housing.
Like many other countries in the world, South Africa is in the throes of an unprecedented housing crisis. It faces a growing challenge in providing all citizens with access to suitable or adequate housing despite the Constitution stating that ‘everyone has the right to have access to adequate housing’ and that the ‘state must take reasonable legislative and other measures, within its available resources, to achieve the progressive realisation of this right.
According to Statistics, South Africa’s Household Survey 2017, 12.1% (1789 million households) of South Africa’s 14.75 million households lived in informal housing in 2011 with Gauteng having 20.4% households living in informal settlements, North West, 18.5% and the Western Cape, 15.1%. Limpopo has the smallest percentage with 4.5% and the Eastern Cape has 6.5%.
I believe the answer is 4. During the reign of Askia Muhammad, the Songhai empire reached its greatest size.
Askia Muhammad was an emperor, military commander, and political reformer of the Songhai Empire in the 15th century. His rule resulted in trade with Europe and Asia, building of lots of schools, and spread of Islam through his empire.
Hope this helps! Please let me know if I'm wrong :)
