Question: Which military branch that Penson may have served for has more active members? Passage 1:The Ohio Country located between Britain's Thirteen Colonies and France's New France saw France and Britain clash. In 1753 the French sent an expedition south from Montreal that began constructing forts in the upper reaches of the Ohio River. In 1754 the Province of Virginia sent the Virginia Regiment led by George Washington to the area to assist in the construction of a British fort at present-day Pittsburgh, but the larger French force had driven away a smaller British advance party and built Fort Duquesne. Washington and some native allies ambushed a company of French scouts at the Battle of Jumonville Glen in late May 1754. In the skirmish the French envoy Joseph Coulon de Jumonville was left dead leading to a diplomatic incident. The French responded in force from Fort Duquesne, and in July Washington was forced to surrender at the Battle of Fort Necessity. Despite the conflict between them, the two nations were not yet formally at war.
 Passage 2:Sigurðsson worked on monitoring and research of the volcanoes of the Caribbean until 1974, when he was appointed professor at the Graduate School of Oceanography, University of Rhode Island. He is best known for his work on the reconstruction of major volcanic eruptions of the past, including the eruption of Vesuvius in Italy in AD 79 and the consequent destruction of the Roman cities of Pompeii and Herculaneum. In 1991 he discovered tektite glass spherules at the Cretaceous–Paleogene boundary (K–T boundary) in Haiti, providing proof for a meteorite impact at the time of the extinction of the dinosaurs. In 2004 he discovered the lost town of Tambora in Indonesia, which was buried by the colossal 1815 explosive eruption of Tambora volcano. In 1999, Haraldur Sigurdsson published a scholarly account of the history of volcanology. He was also editor in chief of the Encyclopedia of Volcanoes, also published in 1999. He was awarded the Coke Medal of the Geological Society of London in 2004.
 Passage 3:Penson's professional career began in April 1954 after he had had a successful three-year skein as a pitcher while he served in the military. Penson won 50 games pitching for his base team, although sources disagree about the branch in which he served, reported as the United States Air Force and the U.S. Army. Penson made the Phillies out of training camp in 1954 as a member of the team's early-season, 28-man roster. His five games pitched included three starts, and he split two decisions. His lone MLB win came in his first start, on Sunday, May 16, 1954. in the second game of a doubleheader at Connie Mack Stadium. He went six innings against the St. Louis Cardinals, and allowed four hits, four bases on balls, and one earned run. But he was forced to leave the game leading 6–3 when the game was suspended because of Pennsylvania blue laws prohibiting sporting events on Sunday evenings. The game resumed on Monday, May 17, and Philadelphia went on to win, 8–4; veteran Murry Dickson nailed down the save with three innings of one-run relief.
