Why were some serbians and bosnians angry with austria-hungary in 1914?
austria-hungary had taken over bosnia and dominated serbia.
austria-hungary refused to trade with either country.
austria-hungary would not allow religious freedom in either country.
austria-hungary wanted to build a railroad through the center of both countries.

Austro Hungary has the intention to build an international railroad, but it would only pass through Serbia, not through Bosnia, and connect Europe with Istanbull and continue to the Middle East. Some theorists claim that this was the main reason for the Austrian desire to dominate Serbia. That is why, in the ultimatum set to Serbia, Austria, among many points, also demanded full control of domestic affairs in the country. This request was the only one that was rejected by Serbia, and was formally the reason for the declaration  of the war. On the other hand, dissatisfaction has been growing in Bosnia over the years since the Austrian annexation.

The answer is A.

although the crusades failed to capture jerusalem, they had several major impacts on western europe. they increased the authority of the king: sometimes nobles died in battle without leaving an heir in which case the king got their land. kings passed taxes to pay for the crusades.

the industrial development of cities in the ruhr area in the nineteenth century is described. the research was based on english and german language sources. several factors that shaped growth and paths of the cities were categorized and analyzed. they are locations, resources, traditions, entrepreneurs, and technological developments. locations and resources were the most important among them; other factors may be regarded as consequences from locations and resources. among the cities, bochum, essen, gelsenkirchen, and dortmund had the richest resources and most favorable locations in the transportation network and grew to be the largest cities in the ruhr area near the end of the nineteenth century. riverside location was also a favorable factor for the development, as shown in the development of duisburg on the confluence of rhine and ruhr. resource distribution can explain the rise of textile industry, metallurgical industry, and coal and iron industries, and the northward progression of the mining industry. tradition was an important factor for cities such as krefeld, barmen, elberfeld, solingen, and remscheid, which experienced development based on their traditions through the nineteenth century. various entrepreneurs exerted influences within and beyond the local level over the ruhr area. technological development stimulated the northward progression of the mining industry and the deep connection between the coal and the iron industries.
