Question: Switzerland has a dense network of cities, where large, medium and small cities are complementary. The plateau is very densely populated with about 450 people per km2 and the landscape continually shows signs of human presence. The weight of the largest metropolitan areas, which are Zurich, GenevaLausanne, Basel and Bern tend to increase. In international comparison the importance of these urban areas is stronger than their number of inhabitants suggests. In addition the two main centers of Zurich and Geneva are recognized for their particularly great quality of life.
Is there an answer to this question: Which 2 centers are recognized for their particularly great quality of life?

Answer: Zurich and Geneva

Question: As a result of the three Carnatic Wars, the British East India Company gained exclusive control over the entire Carnatic region of India. The Company soon expanded its territories around its bases in Bombay and Madras; the Anglo-Mysore Wars (17661799) and later the Anglo-Maratha Wars (17721818) led to control of the vast regions of India. Ahom Kingdom of North-east India first fell to Burmese invasion and then to British after Treaty of Yandabo in 1826. Punjab, North-West Frontier Province, and Kashmir were annexed after the Second Anglo-Sikh War in 1849; however, Kashmir was immediately sold under the Treaty of Amritsar to the Dogra Dynasty of Jammu and thereby became a princely state. The border dispute between Nepal and British India, which sharpened after 1801, had caused the Anglo-Nepalese War of 181416 and brought the defeated Gurkhas under British influence. In 1854, Berar was annexed, and the state of Oudh was added two years later.
Is there an answer to this question: When were the Anglo-Maratha Wars fought?

Answer: 17721818

Question: Vietnam: The event was held in Ho Chi Minh City on April 29. Some 60 torchbearers carried the torch from the downtown Opera House to the Military Zone 7 Competition Hall stadium near Tan Son Nhat International Airport along an undisclosed route. Vietnam is involved in a territorial dispute with China (and other countries) for sovereignty of the Spratly and Paracel Islands; tensions have risen recently[when?] following reports that the Chinese government had established a county-level city named Sansha in the disputed territories, resulting in anti-Chinese demonstrations in December 2007 in Hanoi and Ho Chi Minh City. However to sustain its relationship with China the Vietnamese government has actively sought to head off protests during the torch relay, with Prime Minister Nguyen Tan Dung warning government agencies that "hostile forces" may try to disrupt the torch relay.
Is there an answer to this question: Where was the torch event held in Vietnam?

Answer: Ho Chi Minh City

Question: Lasers emitting in the red region of the spectrum have been available since the invention of the ruby laser in 1960. In 1962 the red heliumneon laser was invented, and these two types of lasers were widely used in many scientific applications including holography, and in education. Red heliumneon lasers were used commercially in LaserDisc players. The use of red laser diodes became widespread with the commercial success of modern DVD players, which use a 660 nm laser diode technology. Today, red and red-orange laser diodes are widely available to the public in the form of extremely inexpensive laser pointers. Portable, high-powered versions are also available for various applications. More recently, 671 nm diode-pumped solid state (DPSS) lasers have been introduced to the market for all-DPSS laser display systems, particle image velocimetry, Raman spectroscopy, and holography.
