QUES: From the early 1930s eight countries developed radar, these developments were sufficiently advanced by the late 1930s for development work on sound locating acoustic devices to be generally halted, although equipment was retained. Furthermore, in Britain the volunteer Observer Corps formed in 1925 provided a network of observation posts to report hostile aircraft flying over Britain. Initially radar was used for airspace surveillance to detect approaching hostile aircraft. However, the German Wurzburg radar was capable of providing data suitable for controlling AA guns and the British AA No 1 Mk 1 GL radar was designed to be used on AA gun positions.
Where was the Observer Corps based?

ANS: Britain

QUES: The city generally has a climate with warm days followed by cool nights and mornings. Unpredictable weather is expected, given that temperatures can drop to 1 C (34 F) or less during the winter. During a 2013 cold front, the winter temperatures of Kathmandu dropped to 4 C (25 F), and the lowest temperature was recorded on January 10, 2013, at 9.2 C (15.4 F). Rainfall is mostly monsoon-based (about 65% of the total concentrated during the monsoon months of June to August), and decreases substantially (100 to 200 cm (39 to 79 in)) from eastern Nepal to western Nepal. Rainfall has been recorded at about 1,400 millimetres (55.1 in) for the Kathmandu valley, and averages 1,407 millimetres (55.4 in) for the city of Kathmandu. On average humidity is 75%. The chart below is based on data from the Nepal Bureau of Standards & Meteorology, "Weather Meteorology" for 2005. The chart provides minimum and maximum temperatures during each month. The annual amount of precipitation was 1,124 millimetres (44.3 in) for 2005, as per monthly data included in the table above. The decade of 2000-2010 saw highly variable and unprecedented precipitation anomalies in Kathmandu. This was mostly due to the annual variation of the southwest monsoon.[citation needed] For example, 2003 was the wettest year ever in Kathmandu, totalling over 2,900 mm (114 in) of precipitation due to an exceptionally strong monsoon season. In contrast, 2001 recorded only 356 mm (14 in) of precipitation due to an extraordinarily weak monsoon season.
About what percentage of Kathmandu's annual rainfall falls during the monsoon months?

ANS: 65

QUES: In recent years, the city has experienced steady population growth, and has been faced with the issue of accommodating more residents. In 2006, after growing by 4,000 citizens per year for the previous 16 years, regional planners expected the population of Seattle to grow by 200,000 people by 2040. However, former mayor Greg Nickels supported plans that would increase the population by 60%, or 350,000 people, by 2040 and worked on ways to accommodate this growth while keeping Seattle's single-family housing zoning laws. The Seattle City Council later voted to relax height limits on buildings in the greater part of Downtown, partly with the aim to increase residential density in the city centre. As a sign of increasing inner-city growth, the downtown population crested to over 60,000 in 2009, up 77% since 1990.
How much increase in population has the inner Seattle city had since 1990?

ANS: 77%

QUES: Thomas J. Watson, Sr., fired from the National Cash Register Company by John Henry Patterson, called on Flint and, in 1914, was offered CTR. Watson joined CTR as General Manager then, 11 months later, was made President when court cases relating to his time at NCR were resolved. Having learned Patterson's pioneering business practices, Watson proceeded to put the stamp of NCR onto CTR's companies. He implemented sales conventions, "generous sales incentives, a focus on customer service, an insistence on well-groomed, dark-suited salesmen and had an evangelical fervor for instilling company pride and loyalty in every worker". His favorite slogan, "THINK", became a mantra for each company's employees. During Watson's first four years, revenues more than doubled to $9 million and the company's operations expanded to Europe, South America, Asia and Australia. "Watson had never liked the clumsy hyphenated title of the CTR" and chose to replace it with the more expansive title "International Business Machines". First as a name for a 1917 Canadian subsidiary, then as a line in advertisements. For example, the McClures magazine, v53, May 1921, has a full page ad with, at the bottom:
The revenues did what under the first 4 years of Watson being president?

ANS:
more than doubled to $9 million
