Article: Under the 1830 Act any householder who paid rates could apply, with a one-off payment of two guineas (roughly equal in value to £168 today), to sell beer or cider in his home (usually the front parlour) and even to brew his own on his premises. The permission did not extend to the sale of spirits and fortified wines, and any beer house discovered selling those items was closed down and the owner heavily fined. Beer houses were not permitted to open on Sundays. The beer was usually served in jugs or dispensed directly from tapped wooden barrels on a table in the corner of the room. Often profits were so high the owners were able to buy the house next door to live in, turning every room in their former home into bars and lounges for customers.

Question: What did the Beer Act allow a householder to sell from his home?
Ans: beer or cider


Article: Airport construction boomed during the 1960s with the increase in jet aircraft traffic. Runways were extended out to 3,000 m (9,800 ft). The fields were constructed out of reinforced concrete using a slip-form machine that produces a continual slab with no disruptions along the length. The early 1960s also saw the introduction of jet bridge systems to modern airport terminals, an innovation which eliminated outdoor passenger boarding. These systems became commonplace in the United States by the 1970s.

Question: When were jet bridge systems introduced to modern airport terminals?
Ans: early 1960s


Article: The Sumerians developed a complex system of metrology c. 4000 BC. This advanced metrology resulted in the creation of arithmetic, geometry, and algebra. From c. 2600 BC onwards, the Sumerians wrote multiplication tables on clay tablets and dealt with geometrical exercises and division problems. The earliest traces of the Babylonian numerals also date back to this period. The period c. 2700 – 2300 BC saw the first appearance of the abacus, and a table of successive columns which delimited the successive orders of magnitude of their sexagesimal number system. The Sumerians were the first to use a place value numeral system. There is also anecdotal evidence the Sumerians may have used a type of slide rule in astronomical calculations. They were the first to find the area of a triangle and the volume of a cube.

Question: From the Sumerian metrology sprang forth the creation of what disciplines? 
Ans: arithmetic, geometry, and algebra


Article: In 1899, the local postage stamps were overprinted "Guam" as was done for the other former Spanish colonies, but this was discontinued shortly thereafter and regular U.S. postage stamps have been used ever since. Because Guam is also part of the U.S. Postal System (postal abbreviation: GU, ZIP code range: 96910–96932), mail to Guam from the U.S. mainland is considered domestic and no additional charges are required. Private shipping companies, such as FedEx, UPS, and DHL, however, have no obligation to do so, and do not regard Guam as domestic.

Question: In what year was the local postage stamp overprinted and has since been replaced?
Ans:
1899
