Question: But Sebastião de Melo's greatest reforms were economic and financial, with the creation of several companies and guilds to regulate every commercial activity. He demarcated the region for production of Port to ensure the wine's quality, and this was the first attempt to control wine quality and production in Europe. He ruled with a strong hand by imposing strict law upon all classes of Portuguese society from the high nobility to the poorest working class, along with a widespread review of the country's tax system. These reforms gained him enemies in the upper classes, especially among the high nobility, who despised him as a social upstart.
Is there an answer to this question: Among which class did de Melo's reforms gain him the most enemies?

Answer: especially among the high nobility


Question: Major outputs for the state include textiles, cotton, cattle, and electrical power. Tennessee has over 82,000 farms, roughly 59 percent of which accommodate beef cattle. Although cotton was an early crop in Tennessee, large-scale cultivation of the fiber did not begin until the 1820s with the opening of the land between the Tennessee and Mississippi Rivers. The upper wedge of the Mississippi Delta extends into southwestern Tennessee, and it was in this fertile section that cotton took hold. Soybeans are also heavily planted in West Tennessee, focusing on the northwest corner of the state.
Is there an answer to this question: Which river landform partly in Tennessee provided the most fertile land for cotton production?

Answer: Mississippi Delta

Question: In South Africa, the period of colonization resulted in many unions and marriages between European men and African women from various tribes, resulting in mixed-race children. As the Europeans acquired territory and imposed rule over the Africans, they generally pushed mixed-race and Africans into second-class status. During the first half of the 20th century, the Afrikaaner-dominated government classified the population according to four main racial groups: Black, White, Asian (mostly Indian), and Coloured. The Coloured group included people of mixed Bantu, Khoisan, and European descent (with some Malay ancestry, especially in the Western Cape). The Coloured definition occupied an intermediary political position between the Black and White definitions in South Africa. It imposed a system of legal racial segregation, a complex of laws known as apartheid.
Is there an answer to this question: What class were Africans and Mixed Race children considered?

Answer:
second-class
