It was Russia, it should be noted though, that Iceland made it clear that the treaty would be put in effect
Slavic and Scandinavian countries are very rich in resources, and Russia wanted to control most trade in Europe until the collapse of the Soviet Union. More trade = More power and they were still recovering after the HARD losses when the Germans' invaded Leningrad and the war.
Answer: B. The crowding of people in tenements and slums.
Further detail:
The Industrial Revolution had its beginning in Great Britain, and eventually spread from there. Once the United States became involved, especially in the "Second Industrial Revolution" years (1870-1914), the size and resources of the country allowed the US to become a bigger industrial power than the nations of Europe.
Industrialization also led to the phenomenon of <u>urbanization</u> -- the movement of people away from the rural countryside and into cities. That led to other issues, like sanitation and crime problems in cities. So sanitation and health measures were enacted, and the first police forces were formed.
The overcrowding conditions also meant poor living conditions in tenements and slums. The condition of these sorts of neighborhoods was documented by Jacob Riis, a police reporter in New York. In 1888, Riis took pictures of what life was like in New York City's slums. Using his own photos as well as photos gathered from other photographers, Riis began to give lectures titled, "The Other Half: How It Lives and Dies in New York," in which he would show the pictures on a projection screen and describe for viewers what the situations were like. He gave his lectures in New York City churches. In 1989, a magazine article by Riis (based on his lectures) was published in <em>Scribner's Magazine</em>. The book version was then published in 1890 as <em>How the Other Half Lives: Studies among the Tenements of New York</em>. Riis blamed the poor living conditions on greed and neglect from society's wealthier classes, and called on society to remedy the situation as a moral obligation.
"From the mid-1970s there were new claims for the independent invention of iron smelting on central Niger and from 1994–1999 UNESCO funded an initiative "Les Routes du Fer en Afrique/The Iron Routes in Africa" to investigate the origins and spread of iron metallurgy in Africa. This funded both the conference on the early iron in Africa and the Mediterranean and a volume, published by UNESCO, that has generated much controversy because it included only authors sympathetic to the view that iron was independently invented in Africa. Two major reviews of the evidence were published in the mid-2000s. Both authors concluded that there were major technical flaws in each of the studies claiming the independent invention. Three major issues were identified. The first was whether the material dated by radiocarbon was insecure archaeological association with iron-working residues. (Many of the dates from Niger, for example, were on organic matter in potsherds that were lying on the ground surface together with iron objects). The second issue is the possible effect of "old carbon" - wood or charcoal much older than the time at which iron was smelted. This is a particular problem in Niger, where the charred stumps of ancient trees are a potential source of charcoal and have sometimes been misidentified as smelting furnaces. A third issue is the inherent lack of precision of the radiocarbon method itself in the range from 800 to 400 BC, which is attributable to the irregular production of radiocarbon in the upper atmosphere. Unfortunately, most radiocarbon dates for the initial spread of iron metallurgy in sub-Saharan Africa fall within this range."
