Question: The Roman expansion brought the defeat of the Allobrogi in 121 BC and during the Gallic Wars in 58 BC Julius Caesar overcame the Helvetii. The Rhaetians continued to resist but were eventually conquered when the Romans turned northward to the Danube valley in Austria and defeated the Brigantes. The Romans built settlements in the Alps; towns such as Aosta (named for Augustus) in Italy, Martigny and Lausanne in Switzerland, and Partenkirchen in Bavaria show remains of Roman baths, villas, arenas and temples. Much of the Alpine region was gradually settled by Germanic tribes, (Lombards, Alemanni, Bavarii, and Franks) from the 6th to the 13th centuries mixing with the local Celtic tribes.
Try to answer this question if possible: When did Julius Caesar overcome the Helvetii?
Answer: 58 BC
Question: The region covers an area of 1,579 square kilometres (610 sq mi). The population density is 5,177 inhabitants per square kilometre (13,410/sq mi), more than ten times that of any other British region. In terms of population, London is the 19th largest city and the 18th largest metropolitan region in the world. As of 2014[update], London has the largest number of billionaires (British Pound Sterling) in the world, with 72 residing in the city. London ranks as one of the most expensive cities in the world, alongside Tokyo and Moscow.
Try to answer this question if possible: With which two other cities is London named one of the most expensive in the world?
Answer: Tokyo and Moscow
Question: The former location in Mesa is actually the second HoHoKam Park; the first was built in 1976 as the spring-training home of the Oakland Athletics who left the park in 1979. Apart from HoHoKam Park and Sloan Park the Cubs also have another Mesa training facility called Fitch Park, this complex provides 25,000 square feet (2,300 m2) of team facilities, including major league clubhouse, four practice fields, one practice infield, enclosed batting tunnels, batting cages, a maintenance facility, and administrative offices for the Cubs.
Try to answer this question if possible: Where was the former location in Mesa?
Answer: the second HoHoKam Park
Question: Film speed is used in the exposure equations to find the appropriate exposure parameters. Four variables are available to the photographer to obtain the desired effect: lighting, film speed, f-number (aperture size), and shutter speed (exposure time). The equation may be expressed as ratios, or, by taking the logarithm (base 2) of both sides, by addition, using the APEX system, in which every increment of 1 is a doubling of exposure; this increment is commonly known as a "stop". The effective f-number is proportional to the ratio between the lens focal length and aperture diameter, the diameter itself being proportional to the square root of the aperture area. Thus, a lens set to f/1.4 allows twice as much light to strike the focal plane as a lens set to f/2. Therefore, each f-number factor of the square root of two (approximately 1.4) is also a stop, so lenses are typically marked in that progression: f/1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc.
Try to answer this question if possible: The ratio between the diameter and square root of the aperture is called what?
Answer:
