Article: In Ireland, pubs are known for their atmosphere or "craic". In Irish, a pub is referred to as teach tábhairne ("tavernhouse") or teach óil ("drinkinghouse"). Live music, either sessions of traditional Irish music or varieties of modern popular music, is frequently featured in the pubs of Ireland. Pubs in Northern Ireland are largely identical to their counterparts in the Republic of Ireland except for the lack of spirit grocers. A side effect of "The Troubles" was that the lack of a tourist industry meant that a higher proportion of traditional bars have survived the wholesale refitting of Irish pub interiors in the 'English style' in the 1950s and 1960s. New Zealand sports a number of Irish pubs.

Question: Vis-à-vis pubs in Ireland, what feature do pubs in Northern Ireland lack?
Ans: spirit grocers


Article: Buckingham Palace finally became the principal royal residence in 1837, on the accession of Queen Victoria, who was the first monarch to reside there; her predecessor William IV had died before its completion. While the state rooms were a riot of gilt and colour, the necessities of the new palace were somewhat less luxurious. For one thing, it was reported the chimneys smoked so much that the fires had to be allowed to die down, and consequently the court shivered in icy magnificence. Ventilation was so bad that the interior smelled, and when a decision was taken to install gas lamps, there was a serious worry about the build-up of gas on the lower floors. It was also said that staff were lax and lazy and the palace was dirty. Following the queen's marriage in 1840, her husband, Prince Albert, concerned himself with a reorganisation of the household offices and staff, and with the design faults of the palace. The problems were all rectified by the close of 1840. However, the builders were to return within the decade.

Question: When did Buckingham officially become the principle royal residence?
Ans: 1837

Article: On 1 March 1951 Mao sent a cable to Stalin, in which he emphasized the difficulties faced by Chinese forces and the urgent need for air cover, especially over supply lines. Apparently impressed by the Chinese war effort, Stalin finally agreed to supply two air force divisions, three anti-aircraft divisions, and six thousand trucks. PVA troops in Korea continued to suffer severe logistical problems throughout the war. In late April Peng Dehuai sent his deputy, Hong Xuezhi, to brief Zhou Enlai in Beijing. What Chinese soldiers feared, Hong said, was not the enemy, but that they had nothing to eat, no bullets to shoot, and no trucks to transport them to the rear when they were wounded. Zhou attempted to respond to the PVA's logistical concerns by increasing Chinese production and improving methods of supply, but these efforts were never completely sufficient. At the same time, large-scale air defense training programs were carried out, and the Chinese Air Force began to participate in the war from September 1951 onward.

Question: What did China introduce to the war in 1951?
Ans:
the Chinese Air Force
