Article: A "country pub" by tradition is a rural public house. However, the distinctive culture surrounding country pubs, that of functioning as a social centre for a village and rural community, has been changing over the last thirty or so years. In the past, many rural pubs provided opportunities for country folk to meet and exchange (often local) news, while othersespecially those away from village centresexisted for the general purpose, before the advent of motor transport, of serving travellers as coaching inns.

Question: Over what period of years has the traditional function of country pubs been changing?
Ans: the last thirty

Article: In the last two decades, photovoltaics (PV), also known as solar PV, has evolved from a pure niche market of small scale applications towards becoming a mainstream electricity source. A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. In 1931 a German engineer, Dr Bruno Lange, developed a photo cell using silver selenide in place of copper oxide. Although the prototype selenium cells converted less than 1% of incident light into electricity, both Ernst Werner von Siemens and James Clerk Maxwell recognized the importance of this discovery. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the crystalline silicon solar cell in 1954. These early solar cells cost 286 USD/watt and reached efficiencies of 4.56%. By 2012 available efficiencies exceed 20% and the maximum efficiency of research photovoltaics is over 40%.

Question: What is a solar cell?
Ans: a device that converts light directly into electricity

Article: In an effort to discourage Japanese militarism, Western powers including Australia, the United States, Britain, and the Dutch government in exile, which controlled the petroleum-rich Dutch East Indies, stopped selling oil, iron ore, and steel to Japan, denying it the raw materials needed to continue its activities in China and French Indochina. In Japan, the government and nationalists viewed these embargos as acts of aggression; imported oil made up about 80% of domestic consumption, without which Japan's economy, let alone its military, would grind to a halt. The Japanese media, influenced by military propagandists,[nb 10] began to refer to the embargoes as the "ABCD ("American-British-Chinese-Dutch") encirclement" or "ABCD line".

Question: How did Japan view Western embargos?
Ans: as acts of aggression

Article: Dominic's search for a close relationship with God was determined and unceasing. He rarely spoke, so little of his interior life is known. What is known about it comes from accounts written by people near to him. St. Cecilia remembered him as cheerful, charitable and full of unceasing vigor. From a number of accounts, singing was apparently one of Dominic's great delights. Dominic practiced self-scourging and would mortify himself as he prayed alone in the chapel at night for 'poor sinners.' He owned a single habit, refused to carry money, and would allow no one to serve him.

Question: What did Dominic greatly struggle with?
Ans:
relationship with God
