I would also say C. movement of people to urban areas is the correct answer.
Industrialization meant that the country was becoming more and more technologically advanced. There were new factories, which meant there were new job positions. So obviously people wanted to come to the city in order to pursue a career.
Answer:
The steppe crosses the Russian plain, south of the taiga, penetrating deep into Siberia. It comprises three main types, which run in roughly parallel bands from east to west: forest steppe in the north, through steppe, to semi -desert steppe in the south. Within these belts, zones of temporary inundation on floodplains or in zones of internal drainage provide valuable hay land. The steppe was increasingly ploughed for crops during the twentieth century; initially crops were rotated with naturally regenerated grassland, but from mid-century cultivation was increasingly intensive. During the collective period, the emphasis was on industrial stock rearing, with housed cattle and high inputs; since decollectivization, intensive enterprises are closing for economic reasons, and systems have yet to stabilize. If ploughed land is left undisturbed it will return naturally to steppe vegetation in six to fifteen years. Hay is very important for winter feed, and much is made from seasonally flooded meadows. Many marginal, semi-arid areas of the steppe have been put under crops, but are not economically viable; much of the cereals so produced are fed to livestock, but grain yields are very low and yield no more livestock products than would natural grassland, but at far higher cost. Marginal cropland should return to grass.
The two geographic features are The Andean Mountain range and the Amazon river basin in the northern and central regions of the continent.
The Gallic sack left very few marks on the city, In particular, archaeology has shown it was not burnt.
Rome didn't REgain control of Italy after the Gallic sack in 386, as she didn't have it before. The decisive date was 338 BC when Rome crushed the Latin league. The peace settlement allowed Latins a good many of the benefits of Roman citizenship, and the promise of more. In consequence Rome got stronger and had more manpower with each extension of its territory, and was supreme in Italy after beating the Etruscans and Samnites at Cominium and Aquilonia in 293 BC..
