The causes of World War I included many factors, including the conflicts and antagonisms of the four decades leading up to the war. The Triple Entente was the name given to the loose alignment between the United Kingdom, France, and Russia after the signing of the Anglo-Russian Entente in 1907. The alignment of the three powers, supplemented by various agreements with Japan, the United States, and Spain, constituted a powerful counterweight to the Triple Alliance of Germany, Austria-Hungary, and Italy, the third having concluded an additional secret agreement with France effectively nullifying her Alliance commitments. Militarism, alliances, imperialism, and nationalism played major roles in the conflict. The immediate origins of the war lay in the decisions taken by statesmen and generals during the July Crisis of 1914, the spark (or casus belli) for which was the assassination of Archduke Franz Ferdinand of Austria.
When was the Anglo -Russia Entente signed?
A: 1907.

Question: Rome's government, politics and religion were dominated by an educated, male, landowning military aristocracy. Approximately half Rome's population were slave or free non-citizens. Most others were plebeians, the lowest class of Roman citizens. Less than a quarter of adult males had voting rights; far fewer could actually exercise them. Women had no vote. However, all official business was conducted under the divine gaze and auspices, in the name of the senate and people of Rome. "In a very real sense the senate was the caretaker of the Romans' relationship with the divine, just as it was the caretaker of their relationship with other humans".
Is there an answer to this question: Of what class was more than half of Rome's population?

Answer: slave or free non-citizens

QUES: In 1980 half of all the industrial jobs in Mexico were located in Mexico City. Under relentless growth, the Mexico City government could barely keep up with services. Villagers from the countryside who continued to pour into the city to escape poverty only compounded the city's problems. With no housing available, they took over lands surrounding the city, creating huge shantytowns that extended for many miles. This caused serious air pollution in Mexico City and water pollution problems, as well as subsidence due to overextraction of groundwater. Air and water pollution has been contained and improved in several areas due to government programs, the renovation of vehicles and the modernization of public transportation.

How many of the industrial jobs in the county were based in Mexico City in the late 20th century?
What is the answer?
ANS:
