The problem: Answer a question about this article:
The Pacific War saw the Allied powers pitted against the Empire of Japan, the latter briefly aided by Thailand and to a much lesser extent by its Axis allies, Germany and Italy. The war culminated in the atomic bombings of Hiroshima and Nagasaki, and other large aerial bomb attacks by the United States Army Air Forces, accompanied by the Soviet invasion of Manchuria on 8 August 1945, resulting in the Japanese announcement of intent to surrender on 15 August 1945. The formal and official surrender of Japan took place aboard the battleship USS Missouri in Tokyo Bay on 2 September 1945. Following its defeat, Japan's Shinto Emperor stepped down as the divine leader through the Shinto Directive, because the Allied Powers believed this was the major political cause of Japan's military aggression and deconstruction process soon took place to install a new liberal-democratic constitution to the Japanese public as the current Constitution of Japan.
What events ended the war with Japan?
****
The answer: atomic bombings of Hiroshima and Nagasaki


The problem: Answer a question about this article:
The most notable difference is that, contrary to other European heraldic systems, the Jews, Muslim Tatars or another minorities would be given the noble title. Also, most families sharing origin would also share a coat-of-arms. They would also share arms with families adopted into the clan (these would often have their arms officially altered upon ennoblement). Sometimes unrelated families would be falsely attributed to the clan on the basis of similarity of arms. Also often noble families claimed inaccurate clan membership. Logically, the number of coats of arms in this system was rather low and did not exceed 200 in late Middle Ages (40,000 in the late 18th century).
What is the most notable difference between countries?
****
The answer: minorities would be given the noble title


The problem: Answer a question about this article:
Zinc deficiency is crop plants' most common micronutrient deficiency; it is particularly common in high-pH soils. Zinc-deficient soil is cultivated in the cropland of about half of Turkey and India, a third of China, and most of Western Australia, and substantial responses to zinc fertilization have been reported in these areas. Plants that grow in soils that are zinc-deficient are more susceptible to disease. Zinc is primarily added to the soil through the weathering of rocks, but humans have added zinc through fossil fuel combustion, mine waste, phosphate fertilizers, pesticide (zinc phosphide), limestone, manure, sewage sludge, and particles from galvanized surfaces. Excess zinc is toxic to plants, although zinc toxicity is far less widespread.
Growing plants in zinc deficient soil makes them more susceptible to what?
****
The answer: disease.


The problem: Answer a question about this article:
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?
****
The answer:
Radoje Ljutovac
