Context and question: In the 1950s after PRC was established by CPC, the government invested heavily in the city to build a series of state-owned heavy industries, as part of the national plan of rapid industrialization, converting it into a heavy industry production centre of East China. Overenthusiastic in building a "world-class" industrial city, the government also made many disastrous mistakes during development, such as spending hundreds of millions of yuan to mine for non-existent coal, resulting in negative economic growth in the late 1960s. From 1960s to 1980s there were Five Pillar Industries, namely, electronics, cars, petrochemical, iron and steel, and power, each with big state-owned firms. After the Reform and Opening recovering market economy, the state-owned enterprises found themselves incapable of competing with efficient multinational firms and local private firms, hence were either mired in heavy debt or forced into bankruptcy or privatization and this resulted in large numbers of layoff workers who were technically not unemployed but effectively jobless.
The government wanted Nanjing to be what kind of industrial city?
Answer: "world-class"
Context and question: It is widely assumed that architectural success was the product of a process of trial and error, with progressively less trial and more replication as the results of the process proved increasingly satisfactory. What is termed vernacular architecture continues to be produced in many parts of the world. Indeed, vernacular buildings make up most of the built world that people experience every day. Early human settlements were mostly rural. Due to a surplus in production the economy began to expand resulting in urbanization thus creating urban areas which grew and evolved very rapidly in some cases, such as that of Catal Hoyuk in Anatolia and Mohenjo Daro of the Indus Valley Civilization in modern-day Pakistan.
Why did the economy begin to expand?
Answer: a surplus in production
Context and question: On 30 September 1915, troops of the Serbian Army observed three enemy aircraft approaching Kragujevac. Soldiers shot at them with shotguns and machine-guns but failed to prevent them from dropping 45 bombs over the city, hitting military installations, the railway station and many other, mostly civilian, targets in the city. During the bombing raid, private Radoje Ljutovac fired his cannon at the enemy aircraft and successfully shot one down. It crashed in the city and both pilots died from their injuries. The cannon Ljutovac used was not designed as an anti-aircraft gun, it was a slightly modified Turkish cannon captured during the First Balkan War in 1912. This was the first occasion in military history that a military aircraft was shot down with ground-to-air fire.
Which private shot down one aircraft with a cannon?
Answer:
Radoje Ljutovac
