Your answer is a, b and c
Answer: Petroleum exports
Explanation:
Saudi Arabia's oil exports are a major economic branch. Almost all economic income in the country (about 90%) is based on oil exports. Oil in Saudi Arabia was discovered in 1932, and since then, it has become a major economic factor in the country. Before the discovery of oil, Saudi Arabia was a poor country. The main activities were livestock and agriculture. Before discovering oil, Saudi Arabia based its economy on religious tourism, which still plays an important role in the country's economy.
The Apalachee spoke the Apalachee language, a Muskogean language which became extinct. It was documented by Spanish settlers in letters written during the Spanish Colonial period. Around 1100 indigenous peoples began to cultivate crops. Agriculture was important in the area that became the Apalachee domain.
