Which of these BEST describes why Georgia was important to United States during World War I?
astraxan [27]

At the beginning of World War I the United Statesdid not want to participate in the war. US President at the time Woodrow Wilson was very strong on the believe that the United States should keep its neutrality. Eventually, the United States was not able to maintain that neutrality and in April 6th, 1917, there was an official declaration of war on Germany thus affirming the United States entrance into World War I.

At the beginning of the war and for almost two years, just about all newspapers in Georgia had articles describing the negative consequences of the war for the State´s economic situation. Suddenly, there was a complete turn around on the position of the newspapers, and almost immediately they were in favor of the war effort, and all the articles became very patriotic and anti German.

Georgia was very important for the war effort between 1917 and 1918 because the State had many training camps, which were federal installations and they facilitated the formation of qualified men to the war. D will be the correct answer. The State contributed with more than 100 thousand men and women on behalf of the United States.

Answer:

\huge\colorbox{pink}{answer}

  1. 1]The Culture in Africa is varied and manifold, consisting of a mixture of countries with various tribes that each have their own unique characteristic from the continent of Africa. It is a product of the diverse populations that today inhabit the continent of Africa and the African Diaspora. African culture is expressed in its arts and crafts, folklore and religion, clothing, cuisine, music and languages.[2] Expressions of culture are abundant within Africa, with large amounts of cultural diversity being found not only across different countries but also within single countries. Even though African cultures are widely diverse, they are also, when closely studied, seen to have many similarities; for example, the morals they uphold, their love and respect for their culture as well as the strong respect they hold for the aged and the important, i.e. kings and chiefs.The geography of Africa helped to shape the history and development of the culture and civilizations of Ancient Africa. The geography impacted where people could live, important trade resources such as gold and salt, and trade routes that helped different civilizations to interact and develop.
  2. African Americans advanced civilization during the middle ages:
  3. The Kingdom of Kush--- Though often overshadowed by its Egyptian neighbors to the north, the Kingdom of Kush stood as a regional power in Africa for over a thousand years. This ancient Nubian empire reached its peak in the second millennium B.C., when it ruled over a vast swath of territory along the Nile River in what is now Sudan
  4. The Land of Punt--- Few African civilizations are as mysterious as Punt. Historical accounts of the kingdom date to around 2500 B.C., when it appears in Egyptian records as a "Land of the Gods" rich in ebony, gold, myrrh and exotic animals such as apes and leopards. Egyptians are known to have sent huge caravans and flotillas on trade missions to Punt
  5. The Arabs and their religion of Islam had a great impact on Africa. By the eighth century, the entire northern coast of Africa was under Arab rule. As a result, the civilizations of modern-day nations such as Egypt, Libya, and Morocco adopted an Arab identity. The Arab demand for gold was a driving force in the development and expansion of West African kingdoms. The kingdoms gained tremendous wealth by selling gold to the Arabs. The Arab slave trade also had a deep impact on Africa. Millions of Africans were displaced from their homes and sold into slavery in the Islamic empire.
