Answer: C.They lived in settled villages and farmed the land.
The Puebloans or Pueblo people are Native Americans that inhabit the Southwestern United States and share common cultural practices. At the time of discovery by the Europeans, the Pueblo people lived in complex, multi-story villages built of adobe, stone and other local materials. The Spanish colonizers called this <em>pueblos</em> (towns).
The Pueblo people developed planned villages composed of large terraced buildings made out of adobe by 1050. The largest of these villages, Pueblo Bonito in Chaco Canyon, New Mexico, contained around 700 rooms in five stories; it may have housed as many as 1000 persons.
The Pueblo people relied on crops that survived the arid conditions of the area. Corn, beans and squash were their staple crops.
Answer:
The correct answer is: political instability, military conflict, and economic crisis.
Political instability: at the end of the 4th century AD, the Roman empire was going through a political crisis. While the emperor Theodosius tried to handle the social uprisings between Christians and non-Christians, he was struggling against the usurper Magnus Maximus and the empire was facing cases of corruption in the political sphere that diverted public funds from the military needs. Due to these reasons and for administrative purposes, Theodosius decided to establish Christianity as the official religion of the empire and divided the empire into two parts: the Western Roman Empire, with its capital in Ravenna, and the Eastern Roman Empire, with its capital in Constantinople.
Military conflict: while the Roman Empire was facing these internal problems that weakened it, there were urgent problems in its borders since many barbarian invaders were attacking Roman positions from the outside. The Huns from the East, led by Attila, devastated a great portion of the empire, Saxons invaded Britain, Goths and Lombard people from the North as well invaded Italy and Hispania. The Roman army for the first time was not in the position of facing so many fronts at the same time.
Economic crisis: the enormous Roman administrative device was going through a financial crisis. It was so big that it did not find the necessary resources to satisfy its needs. Gold mines that used to fuel the economy were very far away, difficult to achieve, and the Empire had to make a large number of official coins out of copper provoking a great devaluation of the Roman currency.
Explanation:
Robust knowledge is knowledge that has stood the test of time and survived constant criticism. When a piece of knowledge is examined for its truthfulness, critics make a consensus over whether it's correct or not. The knowledge becomes robust if a consensus is reached on its truthfulness and if it survives criticism from different sides and angles. This is difficult to apply to history because those who make history usually have a different perception of what happened. What was an assassination in the mind of one country, is a move of fighting for freedom in another country. That's why a consensus needs to be made on a global scale regarding historical developments and it is done through the academia where people write papers and critics from all over the world critique them to eventually reach an idea of truthful global history.
