[EX Q]: Question: Who is the leader of the largest party in Wallonia? Passage:Following the Belgian general election held on 13 June 2010, a process of cabinet formation started in Belgium. The election produced a very fragmented political landscape, with 11 parties elected to the Chamber of Representatives, none of which won more than 20% of the seats. The Flemish-Nationalist New Flemish Alliance (N-VA), the largest party in Flanders and the country as a whole, controlled 27 of 150 seats in the lower chamber. The Francophone Socialist Party (PS), the largest in Wallonia, controlled 26 seats. Cabinet negotiations continued for a long time. On 1 June 2011, Belgium matched the record for time taken to form a new democratic government after an election, at 353 days, held until then by Cambodia in 20032004. On 11 October 2011, the final agreement for institutional reform was presented to the media. A government coalition was named on 5 December 2011 and sworn in after a total of 541 days of negotiations and formation on 6 December 2011, and 589 days without an elected government with Elio Di Rupo named Prime Minister of the Di Rupo I Government.

[EX Q]: Question: What is the population of the country where Mello was the head of a Portuguese delegation to the World Leprosy Conference? Passage:During the same period, he also served as Chief of Public Health for Portuguese India. He undertook a postgraduate course in parasitology in Kaiser Willhelm Institute fuer Biologie, Berlin, and at the Max Planck Institute, Potsdam, Germany from 192223. In 1922, at the age of 35, Mello became a Colonel in the Portuguese Army Medical Corps, achieving the highest rank in the medical military hierarchy of that time, exclusively through merits in the medical campaigns on Public Health which he carried out in Goa, Daman, Diu, and in Angola. Mello was the head of a Portuguese delegation to the World Leprosy Conference in Cuba and is known to have attended at least 40 World Conferences, including the All India Sanitary Conference in Lucknow (1914) and the Third Entomological Meeting in Lucknow (1914) where, at the invitation of the Governor-General of India, he lectured on medical mycology. His researches in tropical medicine brought him international fame and recognition as a world-renowned expert on the subject. Mello published more than 200 research papers on bacteriology in Portuguese, French and English journals. He founded the following medical journals in Goa, Boletim Geral de Medicina, Arquivos Indo-Portugueses de Medicina e Historia Natural, and Arquivos da Escola MedicoCirurgica de Nova Goa. His work in French entitled, A la veille du Centenaire (On the eve of the Centenary) elaborated in great detail the contributions of Goa Medical College during the first hundred years of its establishment. Separate from his medical career, Mello also authored a book in 1946 on the Bengali poet, Rabindranath Tagore entitled O Cantico da Vida na Poesia Tagoreana (The song of life in the poetry of Tagore).

[EX Q]: Question: What's the highest peak in the mountains that are surrounded by jungles? Passage:In 1950, Admiral Arthur W. Radford, Commander-in-Chief of the United States Pacific Fleet, envisioned an naval base in the Western Pacific to enhance Seventh Fleet capabilities. The Korean War began and the Navy realized it had a need for an air station in the region. Cubi Point in the Philippines was selected, and civilian contractors were initially approached for the project. After seeing the Zambales Mountains and the surrounding jungle, they claimed it could not be done. The U.S. Navy then turned to the Seabees and was told no problem, Can do. The first Seabees to arrive were surveyors of Construction Battalion Detachment 1802. Moblie Comstruction Battalion 3 arrived on 2 October 1951 to get the project going and was joined by MCB 5 in November. Over the next five years, MCBs 2, 7, 9, 11 and CBD 1803 also contributed to the effort. They leveled a mountain to make way for a nearly runway. NAS Cubi Point turned out to be one of the largest earth-moving projects in the world, equivalent to the construction of the Panama Canal. Seabees there moved of dry fill plus another 15 million that was hydraulic fill. The $100million facility was commissioned on 25 July 1956, and comprised an air station with an adjacent pier capable of docking the Navy's largest carriers. Adjusted-for-inflation, today's price-tag for what the Seabees built at Cubi Point would be $906,871,323.53. After decades of use by American forces, Mount Pinatubo erupted in 1991, burying Cubi Point in 18-36 inches of ash. Despite this, the American government wished to keep the Subic Naval Base and signed a treaty with the Philippine government. The treaty was not ratified, however, failing by a slim margin in the Philippine Senate. Attempts to negotiate a new treaty were soon abandoned and the United States was informed that it was to withdraw within one year. U.S. forces withdrew in November 1992, turning over the facility with its airport to the Philippine government.
