Q: Although England's first away kits were blue, England's traditional away colours are red shirts, white shorts and red socks. In 1996, England's away kit was changed to grey shirts, shorts and socks. This kit was only worn three times, including against Germany in the semi-final of Euro 96 but the deviation from the traditional red was unpopular with supporters and the England away kit remained red until 2011, when a navy blue away kit was introduced. The away kit is also sometimes worn during home matches, when a new edition has been released to promote it.

A: What color were England's first away kits?

Q: While there is typically only one conceptual (or logical) and physical (or internal) view of the data, there can be any number of different external views. This allows users to see database information in a more business-related way rather than from a technical, processing viewpoint. For example, a financial department of a company needs the payment details of all employees as part of the company's expenses, but does not need details about employees that are the interest of the human resources department. Thus different departments need different views of the company's database.

A: How many conceptual or physical views of data are there?

Q: Oklahoma City has a very active severe weather season from March through June, especially during April and May. Being in the center of what is colloquially referred to as Tornado Alley, it is prone to especially frequent and severe tornadoes, as well as very severe hailstorms and occasional derechoes. Tornadoes have occurred in every month of the year and a secondary smaller peak also occurs during autumn, especially October. The Oklahoma City metropolitan area is one of the most tornado-prone major cities in the world, with about 150 tornadoes striking within the city limits since 1890. Since the time weather records have been kept, Oklahoma City has been struck by thirteen violent tornadoes, eleven F/EF4s and two F/EF5. On May 3, 1999 parts of southern Oklahoma City and nearby suburban communities suffered from one of the most powerful tornadoes on record, an F5 on the Fujita scale, with wind speeds estimated by radar at 318 mph (510 km/h). On May 20, 2013, far southwest Oklahoma City, along with Newcastle and Moore, was hit again by a EF5 tornado; it was 0.5 to 1.3 miles (0.80 to 2.09 km) wide and killed 23 people. Less than two weeks later, on May 31, another outbreak affected the Oklahoma City area, including an EF1 and an EF0 within the city and a tornado several miles west of the city that was 2.6 miles (4.2 km) in width, the widest tornado ever recorded.
