Student A:It was in the area of architecture that Roman art produced its greatest innovations. Because the Roman Empire extended over so great of an area and included so many urbanized areas, Roman engineers developed methods for city building on a grand scale, including the use of concrete. Massive buildings like the Pantheon and the Colosseum could never have been constructed with previous materials and methods. Though concrete had been invented a thousand years earlier in the Near East, the Romans extended its use from fortifications to their most impressive buildings and monuments, capitalizing on the material's strength and low cost. The concrete core was covered with a plaster, brick, stone, or marble veneer, and decorative polychrome and gold-gilded sculpture was often added to produce a dazzling effect of power and wealth.

Student A:Passage: After the outbreak of World War I the Defence of the Realm Act was passed by Parliament in 1914. One section of the Act concerned the hours pubs could sell alcohol, as it was believed that alcohol consumption would interfere with the war effort. It restricted opening hours for licensed premises to luncheon (12: 00 to 14: 40) and supper (18: 30 to 22: 30). In the late 1980s the licensing laws in England and Wales became less restricted and allowed pubs to allow the consumption of alcohol on the premises from 11: 00 until 23: 00, although nightclubs were allowed to stay open much later. Significantly revised rules were introduced in November 2005, when hour limits were scrapped, and pubs were allowed to apply for licences as permissive as "24 hours a day". In practice, most pubs chose not to apply for licences past midnight.
