The primary cause of the great schism was due to disputes over the authority of the pope. The Roman Pope claimed he held authority over the four eastern patriarchs, while the four eastern patriarchs claimed that the primacy of the patriarch of Rome was only honorary, and thus had authority only over Western Christians.
Though normally dated to 1054, when Pope Leo IX and Patriarch Michael I excommunicated each other, the East -West Schism was really a result of an extended period of estrangement between the two bodies of Churches.
The answer is B. All other answers relating to the graph would be incorrect with the information given
Correct answer: German troops became demoralized and eventually surrendered in the face of the arrival of fresh US troops.
The United States had been providing some support to the Allies prior to its own entry into the war. But when the US joined the effort fully with a declaration of war, that not only meant the arrival of fresh US troops but a commitment of even more American dollars to the Allies' war effort. The American commitment greatly boosted the morale of British and French troops on the Western front and demoralized the German troops.
As to the other answers ...
- Russia did pull out of the war, but that was because it went through a revolution and change of government in its own country, not because of American involvement. Russia's fight was with Germany on the Eastern front, whereas the US entered the war on the Western front.
- No, Mexico did not attack the United States -- although there had been a German diplomatic telegram that had suggested that as a possibility.
- Ottoman forces did their fighting in the Balkans and in the Middle East, and were not involved in the war on the Western front.
The correct answer is C. As a result of political stability in Argentina during the late 1800s, foreign investments increased and the economy growth.
The investments, coming mainly from the Argentine State and the United Kingdom, were destined to areas such as railway development, ports and cool stores. Much of immigration and modern economic activities moved away from the interior of the country, boosting the concentration of development and wealth in the city of Buenos Aires; which became a prosperous and cosmopolitan city.
