Question: Of the grasses that the essex skipper eats, which is the longest? Passage:Eggs are laid in strings on the stems of grasses where they remain over the winter. The Essex skipper's favoured foodplant is cock's-foot (Dactylis glomerata), and it rarely uses the small skipper's favoured foodplant Yorkshire fog. Essex skippers' other foods include creeping soft grass (Holcus mollis), couch grass (Elymus repens), timothy-grass (Phleum pratense), meadow foxtail (Alopecurus pratensis), false brome (Brachypodium sylvaticum) and tor-grass (Brachypodium pinnatum). This skipper's caterpillars emerge in the spring and feed until June before forming shelters from leaves tied with silk at the base of the foodplant to pupate. Adults fly from July through August. Like most skippers, they are fairly strictly diurnal, though individuals are very rarely encountered during the night.

Question: What country did Airey fight for in World War I? Passage:Airey was born in Oldham, Lancashire on 25 August 1894. He joined Robert Watson-Watt in 1924, and was an original member of the radar team, responsible for masts and support equipment. He was Senior Technical Officer at Telecommunications Research Establishment. Alongside Arnold Wilkins, Airey is credited with having discovered Bawdsey Manor, Ordfordnessas a site for the Air Ministry department that was significant in the history of radar. In his book "Three Steps to Victory" Robert Watson-Watt proclaims Joe Airey's greatest constructional achievement as the installation of a mast atop the Great Pyramid at Cheops. During World War I, Airey was a member of the Dunsterforce in the Persia and the Middle East. By the time of his retirement, he was Station Engineer at the Royal Radar Establishment. He was appointed a Member of the Order of the British Empire (MBE) for his services by King George VI in his Birthday Honours on 14 June 1945. Airey died in Poole Dorset on 10 February 1976.

Question: Who presided over the body where the treaty failed ratification by a slim margin? 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 $100 million 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.
