Question: Extract the answer to the question from the following context. Question: What was Austria able to do? Context: Austria was not able to retake Silesia or make any significant territorial gain. However, it did prevent Prussia from invading parts of Saxony. More significantly, its military performance proved far better than during the War of the Austrian Succession and seemed to vindicate Maria Theresa's administrative and military reforms. Hence, Austria's prestige was restored in great part and the empire secured its position as a major player in the European system. Also, by promising to vote for Joseph II in the Imperial elections, Frederick II accepted the Habsburg preeminence in the Holy Roman Empire. The survival of Prussia as a first-rate power and the enhanced prestige of its king and its army, however, was potentially damaging in the long run to Austria's influence in Germany.
Answer: prevent Prussia from invading parts of Saxony

Question: Extract the answer to the question from the following context. Question: During what length of time were the most upgrades done on the port? Context: The port on Montevideo Bay is one of the reasons the city was founded. It gives natural protection to ships, although two jetties now further protect the harbour entrance from waves. This natural port is competitive with the other great port of Rio de la Plata, Buenos Aires. The main engineering work on the port occurred between the years 1870 and 1930. These six decades saw the construction of the port's first wooden pier, several warehouses in La Aguada, the north and south Rambla, a river port, a new pier, the dredged river basin and the La Teja refinery. A major storm in 1923 necessitated repairs to many of the city's engineering works. Since the second half of the 20th century, physical changes have ceased, and since that time the area has degraded due to national economic stagnation.
Answer: six decades

Question: Extract the answer to the question from the following context. Question: What political events interrupted the old world order that was eventually severed by World War I? Context: Ultimately, World War I created a decisive break with the old world order that had emerged after the Napoleonic Wars, which was modified by the mid-19th century's nationalistic revolutions. The results of World War I would be important factors in the development of World War II approximately 20 years later. More immediate to the time, the partitioning of the Ottoman Empire was a political event that redrew the political boundaries of West Asia. The huge conglomeration of territories and peoples formerly ruled by the Sultan of the Ottoman Empire was divided into several new nations. The partitioning brought the creation of the modern Arab world and the Republic of Turkey. The League of Nations granted France mandates over Syria and Lebanon and granted the United Kingdom mandates over Mesopotamia and Palestine (which was later divided into two regions: Palestine and Transjordan). Parts of the Ottoman Empire on the Arabian Peninsula became parts of what are today Saudi Arabia and Yemen.
Answer:
the mid-19th century's nationalistic revolutions
