thank you :)

For the question about the South African government changing its policy of apartheid, the correct answer is option c. The policy changed due to international sanctions and an increase in protests by black South Africans and whites. This can be determined by understanding the historical context and events that took place during that time period. The South African government faced pressure from the international community, which imposed sanctions to oppose the apartheid regime. Additionally, there were significant protests and resistance movements within South Africa, led by both black South Africans and sympathetic white activists, that contributed to the policy's change. These events ultimately played a crucial role in ending apartheid.

Regarding the question about Australia, the correct answer is option b. The continent is crossed by several powerful rivers. To arrive at this answer, it's necessary to evaluate each option and determine which one does not accurately represent Australia. Options a, c, and d are all true statements about Australia. Australia is known for being the flattest continent, with much of the interior being arid plain or dry plateau west of the Great Dividing Range. The area east of the Great Dividing Range indeed has a moist climate. However, option b, which states that the continent is crossed by several powerful rivers, is not true. While Australia does have significant rivers, they are generally not classified as powerful compared to some of the major rivers found on other continents.
