Problem: British night air defences were in a poor state. Few anti-aircraft guns had fire-control systems, and the underpowered searchlights were usually ineffective against aircraft at altitudes above 12,000 ft (3,700 m). In July 1940, only 1,200 heavy and 549 light guns were deployed in the whole of Britain. Of the "heavies", some 200 were of the obsolescent 3 in (76 mm) type; the remainder were the effective 4.5 in (110 mm) and 3.7 in (94 mm) guns, with a theoretical "ceiling"' of over 30,000 ft (9,100 m) but a practical limit of 25,000 ft (7,600 m) because the predictor in use could not accept greater heights. The light guns, about half of which were of the excellent Bofors 40 mm, dealt with aircraft only up to 6,000 ft (1,800 m). Although the use of the guns improved civilian morale, with the knowledge the German bomber crews were facing the barrage, it is now believed that the anti-aircraft guns achieved little and in fact the falling shell fragments caused more British casualties on the ground.
What was the practical ceiling of the effective heavy guns?
The answer is the following: 25,000 ft (7,600 m)

Problem: Arsenal reached the final of the 2007 and 2011 League Cups, losing 21 to Chelsea and Birmingham City respectively. The club had not gained a major trophy since the 2005 FA Cup until 17 May 2014, when Arsenal beat Hull City in the 2014 FA Cup Final, coming back from a 20 deficit to win the match 32. This qualified them for the 2014 FA Community Shield where they would play Premier League champions Manchester City. They recorded a resounding 30 win in the game, winning their second trophy in three months. Nine months after their Community Shield triumph, Arsenal appeared in the FA Cup final for the second year in a row, thrashing Aston Villa 40 in the final and becoming the most successful club in the tournament's history with 12 titles. On 2 August 2015, Arsenal beat Chelsea 10 at Wembley Stadium to retain the Community Shield and earn their 14th Community Shield title.
What team did Arsenal defeat at Wembley in 2015?
The answer is the following: Chelsea

Problem: On April 12, 1776, the colony became the first to instruct its delegates to the Continental Congress to vote for independence from the British Crown, through the Halifax Resolves passed by the North Carolina Provincial Congress. The dates of both of these events are memorialized on the state flag and state seal. Throughout the Revolutionary War, fierce guerrilla warfare erupted between bands of pro-independence and pro-British colonists. In some cases the war was also an excuse to settle private grudges and rivalries. A major American victory in the war took place at King's Mountain along the North CarolinaSouth Carolina border; on October 7, 1780, a force of 1000 mountain men from western North Carolina (including what is today the state of Tennessee)and Southwest Virginia overwhelmed a force of some 1000 British troops led by Major Patrick Ferguson. Most of the soldiers fighting for the British side in this battle were Carolinians who had remained loyal to the Crown (they were called "Tories" or Loyalists). The American victory at Kings Mountain gave the advantage to colonists who favored American independence, and it prevented the British Army from recruiting new soldiers from the Tories.
How many North Carolina mountain men fought at King's Mountain?
The answer is the following: 1000

Problem: Following the adoption of UN Resolution 390A(V) in December 1950, Eritrea was federated with Ethiopia under the prompting of the United States. The resolution called for Eritrea and Ethiopia to be linked through a loose federal structure under the sovereignty of the Emperor. Eritrea was to have its own administrative and judicial structure, its own flag, and control over its domestic affairs, including police, local administration, and taxation. The federal government, which for all intents and purposes was the existing imperial government, was to control foreign affairs (including commerce), defense, finance, and transportation. The resolution ignored the wishes of Eritreans for independence, but guaranteed the population democratic rights and a measure of autonomy.
Which Eritrean wishes did Resolution 390A(V) ignore?
The answer is the following:
independence
