Article: AAA battalions were also used to help suppress ground targets. Their larger 90 mm M3 gun would prove, as did the eighty-eight, to make an excellent anti-tank gun as well, and was widely used late in the war in this role. Also available to the Americans at the start of the war was the 120 mm M1 gun stratosphere gun, which was the most powerful AA gun with an impressive 60,000 ft (18 km) altitude capability. No 120 M1 was ever fired at an enemy aircraft. The 90 mm and 120 mm guns would continue to be used into the 1950s.

Question: What decade were the 90 and 120 millimeter guns used until?
Ans: 1950s


Article: Prior to moving its headquarters to Chicago, aerospace manufacturer Boeing (#30) was the largest company based in Seattle. Its largest division is still headquartered in nearby Renton, and the company has large aircraft manufacturing plants in Everett and Renton, so it remains the largest private employer in the Seattle metropolitan area. Former Seattle Mayor Greg Nickels announced a desire to spark a new economic boom driven by the biotechnology industry in 2006. Major redevelopment of the South Lake Union neighborhood is underway, in an effort to attract new and established biotech companies to the city, joining biotech companies Corixa (acquired by GlaxoSmithKline), Immunex (now part of Amgen), Trubion, and ZymoGenetics. Vulcan Inc., the holding company of billionaire Paul Allen, is behind most of the development projects in the region. While some see the new development as an economic boon, others have criticized Nickels and the Seattle City Council for pandering to Allen's interests at taxpayers' expense. Also in 2006, Expansion Magazine ranked Seattle among the top 10 metropolitan areas in the nation for climates favorable to business expansion. In 2005, Forbes ranked Seattle as the most expensive American city for buying a house based on the local income levels. In 2013, however, the magazine ranked Seattle No. 9 on its list of the Best Places for Business and Careers.

Question: Before they moved to Chicago, what was the biggest company headquartered in Seattle?
Ans: Boeing


Article: Valencia was founded as a Roman colony in 138 BC. The city is situated on the banks of the Turia, on the east coast of the Iberian Peninsula, fronting the Gulf of Valencia on the Mediterranean Sea. Its historic centre is one of the largest in Spain, with approximately 169 hectares; this heritage of ancient monuments, views and cultural attractions makes Valencia one of the country's most popular tourist destinations. Major monuments include Valencia Cathedral, the Torres de Serrans, the Torres de Quart, the Llotja de la Seda (declared a World Heritage Site by UNESCO in 1996), and the Ciutat de les Arts i les Ciències (City of Arts and Sciences), an entertainment-based cultural and architectural complex designed by Santiago Calatrava and Félix Candela. The Museu de Belles Arts de València houses a large collection of paintings from the 14th to the 18th centuries, including works by Velázquez, El Greco, and Goya, as well as an important series of engravings by Piranesi. The Institut Valencià d'Art Modern (Valencian Institute of Modern Art) houses both permanent collections and temporary exhibitions of contemporary art and photography.

Question: What Valencian museum contains pieces by Velazquez and other famous artists?
Ans: Museu de Belles Arts de València


Article: It is a fundamental property of antennas that the electrical characteristics of an antenna described in the next section, such as gain, radiation pattern, impedance, bandwidth, resonant frequency and polarization, are the same whether the antenna is transmitting or receiving. For example, the "receiving pattern" (sensitivity as a function of direction) of an antenna when used for reception is identical to the radiation pattern of the antenna when it is driven and functions as a radiator. This is a consequence of the reciprocity theorem of electromagnetics. Therefore, in discussions of antenna properties no distinction is usually made between receiving and transmitting terminology, and the antenna can be viewed as either transmitting or receiving, whichever is more convenient.

Question: Are essential properties of an antenna changed based on what fungtion they are performing
Ans:
the same
