Input: A cappella
In addition to singing words, some a cappella singers also emulate instrumentation by reproducing instrumental sounds with their vocal cords and mouth. One of the earliest 20th century practitioners of this method were The Mills Brothers whose early recordings of the 1930s clearly stated on the label that all instrumentation was done vocally. More recently, "Twilight Zone" by 2 Unlimited was sung a cappella to the instrumentation on the comedy television series Tompkins Square. Another famous example of emulating instrumentation instead of singing the words is the theme song for The New Addams Family series on Fox Family Channel (now ABC Family). Groups such as Vocal Sampling and Undivided emulate Latin rhythms a cappella. In the 1960s, the Swingle Singers used their voices to emulate musical instruments to Baroque and Classical music. Vocal artist Bobby McFerrin is famous for his instrumental emulation. A cappella group Naturally Seven recreates entire songs using vocal tones for every instrument.

What types of music did the Swingle Singers implement instrumental emulation for?
Output: Baroque and Classical music

Input: Article: In the south, land up to Safdarjung's Tomb was acquired in order to create what is today known as Lutyens' Bungalow Zone. Before construction could begin on the rocky ridge of Raisina Hill, a circular railway line around the Council House (now Parliament House), called the Imperial Delhi Railway, was built to transport construction material and workers for the next twenty years. The last stumbling block was the Agra-Delhi railway line that cut right through the site earmarked for the hexagonal All-India War Memorial (India Gate) and Kingsway (Rajpath), which was a problem because the Old Delhi Railway Station served the entire city at that time. The line was shifted to run along the Yamuna river, and it began operating in 1924. The New Delhi Railway Station opened in 1926 with a single platform at Ajmeri Gate near Paharganj and was completed in time for the city's inauguration in 1931. As construction of the Viceroy's House (the present Rashtrapati Bhavan), Central Secretariat, Parliament House, and All-India War Memorial (India Gate) was winding down, the building of a shopping district and a new plaza, Connaught Place, began in 1929, and was completed by 1933. Named after Prince Arthur, 1st Duke of Connaught (18501942), it was designed by Robert Tor Russell, chief architect to the Public Works Department (PWD).

Now answer this question: In what year did the Imperial Delhi Railway line begin operating?

Output: 1924

Article: Richmond is home to the rapidly developing Virginia BioTechnology Research Park, which opened in 1995 as an incubator facility for biotechnology and pharmaceutical companies. Located adjacent to the Medical College of Virginia (MCV) Campus of Virginia Commonwealth University, the park currently[when?] has more than 575,000 square feet (53,400 m2) of research, laboratory and office space for a diverse tenant mix of companies, research institutes, government laboratories and non-profit organizations. The United Network for Organ Sharing, which maintains the nation's organ transplant waiting list, occupies one building in the park. Philip Morris USA opened a $350 million research and development facility in the park in 2007. Once fully developed, park officials expect the site to employ roughly 3,000 scientists, technicians and engineers.

Question: What was the cost of the Philip Morris R&D facility opened at the Virginia BioTechnology Research Park?
Ans: $350 million

Here is a question about this article: The first known European explorer to reach Bermuda was Spanish sea captain Juan de Bermudez in 1503, after whom the islands are named. He claimed the apparently uninhabited islands for the Spanish Empire. Paying two visits to the archipelago, Bermudez never landed on the islands, but did create a recognisable map of the archipelago. Shipwrecked Portuguese mariners are now thought to have been responsible for the 1543 inscription in Portuguese Rock (previously called Spanish Rock). Subsequent Spanish or other European parties are believed to have released pigs there, which had become feral and abundant on the island by the time European settlement began. In 1609, the English Virginia Company, which had established Jamestown in Virginia (a term originally applied to all of the North American continent) two years earlier, permanently settled Bermuda in the aftermath of a hurricane, when the crew and passengers of the Sea Venture steered the ship onto the surrounding reef to prevent its sinking, then landed ashore.
What is the answer to this question: How many times did Bermudez visit the archipelago?
****
So... two

A series of new editors-in-chief oversaw the company during another slow time for the industry. Once again, Marvel attempted to diversify, and with the updating of the Comics Code achieved moderate to strong success with titles themed to horror (The Tomb of Dracula), martial arts, (Shang-Chi: Master of Kung Fu), sword-and-sorcery (Conan the Barbarian, Red Sonja), satire (Howard the Duck) and science fiction (2001: A Space Odyssey, "Killraven" in Amazing Adventures, Battlestar Galactica, Star Trek, and, late in the decade, the long-running Star Wars series). Some of these were published in larger-format black and white magazines, under its Curtis Magazines imprint. Marvel was able to capitalize on its successful superhero comics of the previous decade by acquiring a new newsstand distributor and greatly expanding its comics line. Marvel pulled ahead of rival DC Comics in 1972, during a time when the price and format of the standard newsstand comic were in flux. Goodman increased the price and size of Marvel's November 1971 cover-dated comics from 15 cents for 36 pages total to 25 cents for 52 pages. DC followed suit, but Marvel the following month dropped its comics to 20 cents for 36 pages, offering a lower-priced product with a higher distributor discount.
What were two of Marvel's comic heroes in fantasy, swords and magic settings?
****
The answer: Conan the Barbarian, Red Sonja

The problem: Answer a question about this article:
In 2003, a congestion charge was introduced to reduce traffic volumes in the city centre. With a few exceptions, motorists are required to pay 10 per day to drive within a defined zone encompassing much of central London. Motorists who are residents of the defined zone can buy a greatly reduced season pass. London government initially expected the Congestion Charge Zone to increase daily peak period Underground and bus users by 20,000 people, reduce road traffic by 10 to 15 per cent, increase traffic speeds by 10 to 15 per cent, and reduce queues by 20 to 30 per cent. Over the course of several years, the average number of cars entering the centre of London on a weekday was reduced from 195,000 to 125,000 cars a 35-per-cent reduction of vehicles driven per day.
What is the daily cost for most drivers to operate their cars within a given zone in the center of London?
