In addition to the Jazz Festival (described above), New Haven serves as the home city of the annual International Festival of Arts and Ideas. New Haven's Saint Patrick's Day parade, which began in 1842, is New England's oldest St. Patty's Day parade and draws the largest crowds of any one-day spectator event in Connecticut. The St. Andrew the Apostle Italian Festival has taken place in the historic Wooster Square neighborhood every year since 1900. Other parishes in the city celebrate the Feast of Saint Anthony of Padua and a carnival in honor of St. Bernadette Soubirous. New Haven celebrates Powder House Day every April on the New Haven Green to commemorate the city's entrance into the Revolutionary War. The annual Wooster Square Cherry Blossom Festival commemorates the 1973 planting of 72 Yoshino Japanese Cherry Blossom trees by the New Haven Historic Commission in collaboration with the New Haven Parks Department and residents of the neighborhood. The Festival now draws well over 5,000 visitors. The Film Fest New Haven has been held annually since 1995.
What annual festival, celebrated on New Haven Green, memorializes the New Haven's passage into the Revolutionary War?
Powder House Day

Input: Uranium
In nature, uranium is found as uranium-238 (99.2742%) and uranium-235 (0.7204%). Isotope separation concentrates (enriches) the fissionable uranium-235 for nuclear weapons and most nuclear power plants, except for gas cooled reactors and pressurised heavy water reactors. Most neutrons released by a fissioning atom of uranium-235 must impact other uranium-235 atoms to sustain the nuclear chain reaction. The concentration and amount of uranium-235 needed to achieve this is called a 'critical mass'.

What percentage of natural uranium is isotope 238?
Output: 99.2742%

Input: Article: The single most important piece of Byzantine Christian mosaic art in the East is the Madaba Map, made between 542 and 570 as the floor of the church of Saint George at Madaba, Jordan. It was rediscovered in 1894. The Madaba Map is the oldest surviving cartographic depiction of the Holy Land. It depicts an area from Lebanon in the north to the Nile Delta in the south, and from the Mediterranean Sea in the west to the Eastern Desert. The largest and most detailed element of the topographic depiction is Jerusalem, at the center of the map. The map is enriched with many naturalistic features, like animals, fishing boats, bridges and palm trees

Now answer this question: When was the Madaba Map rediscovered?

Output: 1894

Article: In 1897, Frank Shuman, a U.S. inventor, engineer and solar energy pioneer built a small demonstration solar engine that worked by reflecting solar energy onto square boxes filled with ether, which has a lower boiling point than water, and were fitted internally with black pipes which in turn powered a steam engine. In 1908 Shuman formed the Sun Power Company with the intent of building larger solar power plants. He, along with his technical advisor A.S.E. Ackermann and British physicist Sir Charles Vernon Boys, developed an improved system using mirrors to reflect solar energy upon collector boxes, increasing heating capacity to the extent that water could now be used instead of ether. Shuman then constructed a full-scale steam engine powered by low-pressure water, enabling him to patent the entire solar engine system by 1912.

Question: Who is Frank Shuman?
Ans: a U.S. inventor, engineer and solar energy pioneer

Here is a question about this article: Among all 17 railway stations in Nanjing, passenger rail service is mainly provided by Nanjing Railway Station and Nanjing South Railway Station, while other stations like Nanjing West Railway Station, Zhonghuamen Railway Station and Xianlin Railway Station serve minor roles. Nanjing Railway Station was first built in 1968. In 1999, On November 12, 1999, the station was burnt in a serious fire. Reconstruction of the station was finished on September 1, 2005. Nanjing South Railway Station, which is one of the 5 hub stations on BeijingShanghai High-Speed Railway, has officially been claimed as the largest railway station in Asia and the second largest in the world in terms of GFA (Gross Floor Area). Construction of Nanjing South Station began on 10 January 2008. The station was opened for public service in 2011.
What is the answer to this question: Which station is one of the 5 hub stations on the BeijingShanghai High-Speed Railway line?
****
So... Nanjing South Railway Station

Article: Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes. The Z2, created by German engineer Konrad Zuse in 1939, was one of the earliest examples of an electromechanical relay computer.

Question: When did Konrad Zuse invent the Z2?
Ans:
1939
