Q: Question: Which country today is closest to the Philippine island that was once connected Semporna peninsula? Passage 1:Hadleigh Castle is a ruined fortification in the English county of Essex, overlooking the Thames Estuary from south of the town of Hadleigh. Built after 1215 during the reign of Henry III by Hubert de Burgh, the castle was surrounded by parkland and had an important economic and defensive role. The castle was significantly expanded and remodelled by Edward III, who turned it into a grander property, designed to defend against a potential French attack, as well as to provide the King with a convenient private residence close to London. Built on a soft hill of London clay, the castle has often been subject to subsidence; this, combined with the sale of its stonework in the 16th century, has led to it now being ruined. The remains are now preserved by English Heritage and protected under UK law as a Grade I listed building and scheduled monument.
 Passage 2:Kuenn was born in West Allis, Wisconsin, but raised in neighboring Milwaukee, Wisconsin and attended Lutheran High School. He was the only child born to German-Americans Harvey and Dorothy (Wrensch) Kuenn. He once kicked (dropkicked) a 53-yard field goal for Lutheran in a football game, which is tied for the eighth-longest field goal in Wisconsin high school football history. He played collegiate baseball at the University of Wisconsin–Madison, where he was a member of Delta Upsilon fraternity. Signed by Detroit as an amateur free agent in 1952, Kuenn was named the starting shortstop after joining the team late in the season. In his first full season in 1953, he hit .308 with 94 runs and led the major leagues with 209 hits, setting a major league rookie record with 167 singles. He received the American League Rookie of the Year and TSN Rookie of the Year awards. Also in that season, he received the first of his ten consecutive selections to the All-Star Game. On October 29, 1955, he married former Miss Wisconsin 1954, Dixie Ann Sarchet in her hometown of Stevens Point, Wisconsin. 
 Passage 3:During the last ice age, the peninsula was connected by an isthmus to the island of Mindanao in the Philippines with the former isthmus included what is now the active volcanic island of Jolo, located at . In the peninsula also located the Skull Hill (Bukit Tengkorak) which consisted largely of numerous isolated hills and mountains, mostly being an extinct volcanoes from the era of Pliocene to Quaternary. Based on survey by Geological Department of Kota Kinabalu, the Skull Hill is said to be an island in its previous form but since the coral limestone terrace of the peninsula have risen from between 100 metres to 130 metres in the past 20,000 years, the hill are not island but a mountainous ridge near the coast. Through a survey on the geothermal presence in the peninsula, the area have a potential to develop geothermal energy as part of the Sabah's renewable energy. The narrow continental shelf fronting the coastal areas of both Dent and Semporna Peninsulas also could be exposed to future tsunamis with the active fault in the eastern coast.
