Problem: British Empire:

In 1919, the frustrations caused by delays to Irish home rule led members of Sinn Fein, a pro-independence party that had won a majority of the Irish seats at Westminster in the 1918 British general election, to establish an Irish assembly in Dublin, at which Irish independence was declared. The Irish Republican Army simultaneously began a guerrilla war against the British administration. The Anglo-Irish War ended in 1921 with a stalemate and the signing of the Anglo-Irish Treaty, creating the Irish Free State, a Dominion within the British Empire, with effective internal independence but still constitutionally linked with the British Crown. Northern Ireland, consisting of six of the 32 Irish counties which had been established as a devolved region under the 1920 Government of Ireland Act, immediately exercised its option under the treaty to retain its existing status within the United Kingdom.

What treaty was signed after the Anglo-Irish War?

Problem: The fairs held at the shrines of Sufi saints are called urs. They generally mark the death anniversary of the saint. On these occasions devotees assemble in large numbers and pay homage to the memory of the saint. Soul inspiring music is played and devotees dance in ecstasy. The music on these occasions is essentially folk and appealing. It forms a part of the folk music through mystic messages. The most important urs are: urs of Data Ganj Buksh at Lahore, urs of Hazrat Sultan Bahu at Jhang, urs of Hazrat Shah Jewna at Jhang, urs of Hazrat Mian Mir at Lahore, urs of Baba Farid Ganj Shakar at Pakpattan, urs of Hazrat Bahaudin Zakria at Multan, urs of Sakhi Sarwar Sultan at Dera Ghazi Khan, urs of Shah Hussain at Lahore, urs of Hazrat Bulleh Shah at Kasur, urs of Hazrat Imam Bari (Bari Shah Latif) at Rawalpindi-Islamabad and urs of Shah Inayar Qadri (the murrshad of Bulleh Shah) in Lahore.

The aircraft carrier dramatically changed naval combat in World War II, because air power was becoming a significant factor in warfare. The advent of aircraft as focal weapons was driven by the superior range, flexibility and effectiveness of carrier-launched aircraft. They had higher range and precision than naval guns, making them highly effective. The versatility of the carrier was demonstrated in November 1940 when HMS Illustrious launched a long-range strike on the Italian fleet at their base in Taranto, signalling the beginning of the effective and highly mobile aircraft strikes. This operation incapacitated three of the six battleships at a cost of two torpedo bombers. World War II in the Pacific Ocean involved clashes between aircraft carrier fleets. The 1941 Japanese surprise attack on Pearl Harbor was a clear illustration of the power projection capability afforded by a large force of modern carriers. Concentrating six carriers in a single unit turned naval history about, as no other nation had fielded anything comparable. However, the vulnerability of carriers compared to traditional battleships when forced into a gun-range encounter was quickly illustrated by the sinking of HMS Glorious by German battleships during the Norwegian campaign in 1940.
What drove the advent of carrier-launched aircraft as secondary weapons?
A: unanswerable

Context and question: Among other things, the Information Management Group is responsible for the conduct of electronic warfare and the protection of the Armed Forces' communications and computer networks. Within the group, this operational role is fulfilled by the Canadian Forces Information Operations Group, headquartered at CFS Leitrim in Ottawa, which operates the following units: the Canadian Forces Information Operations Group Headquarters (CFIOGHQ), the Canadian Forces Electronic Warfare Centre (CFEWC), the Canadian Forces Network Operation Centre (CFNOC), the Canadian Forces Signals Intelligence Operations Centre (CFSOC), the Canadian Forces Station (CFS) Leitrim, and the 764 Communications Squadron. In June 2011 the Canadian Armed Forces Chief of Force Development announced the establishment of a new organization, the Directorate of Cybernetics, headed by a Brigadier General, the Director General Cyber (DG Cyber). Within that directorate the newly established CAF Cyber Task Force, has been tasked to design and build cyber warfare capabilities for the Canadian Armed Forces.

Question: At the other extreme mountainous regions can be windy, cold, and areas at elevation of 750 meters or more (same elevation as Jerusalem) will usually receive at least one snowfall each year. From May to September, rain in Israel is rare. With scarce water resources, Israel has developed various water-saving technologies, including drip irrigation. Israelis also take advantage of the considerable sunlight available for solar energy, making Israel the leading nation in solar energy use per capita (practically every house uses solar panels for water heating).
Is there an answer to this question: Who leads the nation in solar energy use?

Answer: Israel

Bermuda's national cricket team participated in the Cricket World Cup 2007 in the West Indies. Their most famous player is a 130 kilograms (290 lb) police officer named Dwayne Leverock. But India defeated Bermuda and set a record of 413 runs in a One-Day International (ODI). Bermuda were knocked out of the World Cup. Also very well-known is David Hemp, a former captain of Glamorgan in English first class cricket. The annual "Cup Match" cricket tournament between rival parishes St George's in the east and Somerset in the west is the occasion for a popular national holiday. This tournament began in 1872 when Captain Moresby of the Royal Navy introduced the game to Bermuda, holding a match at Somerset to mark forty years since the unjust thraldom of slavery. The East End versus West End rivalry resulted from the locations of the St. George's Garrison (the original army headquarters in Bermuda) on Barrack Hill, St. George's, and the Royal Naval Dockyard at Ireland Island. Moresby founded the Somerset Cricket Club which plays the St. George's Cricket Club in this game (the membership of both clubs has long been mostly civilian).
What began in 1827?
