Question: Which of the new members in 2006 was older? Passage 1:Ole Miss's 2015 season began with easy victories over FCS foe UT-Martin and the Mountain West's Fresno State, and continued their momentum by defeating then-no.2 Alabama on the road, which would become the signature victory of the Rebels' 2015 campaign. Ole Miss then rose to no.3 in the AP Poll, and although they were heavy favorites in their next matchup against Vanderbilt, they struggled mightily, but ultimately emerged victorious. They Rebels maintained their no.3 ranking before getting blown out by Florida on the road and fell to no.14 before bouncing back against New Mexico State. The Rebels entered their next game with a #13 ranking against rival Memphis, in what was one of the most anticipated in the history of Memphis football. Ole Miss, despite being double digit favorites, lost by 13 points, causing them to fall 11 spots in the rankings to no.24. The Rebels followed with two wins against SEC West opponents Texas A&M and Auburn and climbed to no.18 in the rankings and controlled their own destiny the SEC West, but a heartbreaking loss to Arkansas the following week caused them to fall to second place in the SEC West and to fall out of the rankings for the first time since the 2013 season. However, Ole Miss finished the regular season with double digit wins over ranked SEC Rivals LSU and Mississippi State and rose to no.12 in the College Football Playoff poll, which earned them a Sugar Bowl berth for the first time since 1970, where they defeated no.16 Oklahoma State and ultimately finished ranked no.10 in the AP Poll, their first top-ten finish since 1969.
 Passage 2:Fulber rejoined the band in 2003. The reunited duo released the single "Maniacal" in October of that year. The single peaked at No. 15 on Billboards Hot Dance Singles. The next year, they released the studio album Civilization, which landed the No. 2 position on the German Alternative Albums chart. Peterson later rejoined the band to release Artificial Soldier in 2006. It was the first album to feature new members Jeremy Inkel and Jared Slingerland. The album peaked on Billboards Top Dance/Electronic Albums chart at No. 19. After a problem with the tour bus company, the US tour that year was cut short, and the band returned home to Vancouver after playing roughly half of their scheduled dates; performances in New York and Canada were cancelled.

 Passage 3:Chamberlain then went to Geneva, where he studied under Carl Vogt (a supporter of racial typology at the University of Geneva), Graebe, Müller Argoviensis, Thury, Plantamour, and other professors. He studied systematic botany, geology, astronomy, and later the anatomy and physiology of the human body. Under the tutelage of Professor Julius von Wiesner of the University of Vienna, Chamberlain studied botany in Geneva, earning a Bacheliers en sciences (BSc) physiques et naturelles in 1881. His thesis, Recherches sur la sève ascendante (Studies on rising sap), was not finished until 1897 and did not culminate in a further qualification. The main thrust of Chamberlain's dissertation is that the vertical transport of fluids in vascular plants via xylem cannot be explained by the fluid mechanical theories of the time, but only by the existence of a "vital force" (force vitale) that is beyond the pale of physical measurement. He summarises his thesis in the Introduction: Physical arguments, in particular transpirational pull and root pressure, have since been shown to be adequate for explaining the ascent of sap.

 Passage 2:Peru – country located in western South America, on the Pacific Coast, north of Chile. Peruvian territory was home to several ancient cultures. Ranging from the Norte Chico civilization in the 32nd century BC, the oldest civilization in the Americas and one of the five cradles of civilization, to the Inca Empire, the largest state in pre-Columbian America, the territory now including Peru has one of the longest histories of civilization of any country, tracing its heritage back to the 4th millennia BCE. The Spanish Empire conquered the region in the 16th century and established a Viceroyalty, which included most of its South American colonies. After achieving independence in 1821, Peru has undergone periods of political unrest and fiscal crisis as well as periods of stability and economic upswing.

The platform also features station tiling by Heins & LaFarge, who designed the station plaque in a sans-serif font. The walls are made of small white rectangular tiles, except for the bottom , which is marble. There are also fifteen ceramic plaques toward the top of the platform wall, all of which depict a sloop in the New York Harbor to signify the station's location and use. The top of the wall also includes festooned garlands and station monograms, in addition to ceramic trim where the wall intersects the ceiling. The station artwork on the original exit's landing is a 1990 mural, "South Sails", by former MTA Arts & Design director Sandra Bloodworth. During the 2004 Finding Of No Significant Impact for the station, it was determined that the station was eligible for National Register of Historic Places status.

 Passage 3:The only nation to deploy female combat troops in substantial numbers was Russia. From the onset, female recruits either joined the military in disguise or were tacitly accepted by their units. The most prominent were a contingent of front-line light cavalry in a Cossack regiment commanded by a female colonel, Alexandra Kudasheva. Others included Maria Bochkareva, who was decorated three times and promoted to senior NCO rank, while The New York Times reported that a group of twelve schoolgirls from Moscow had enlisted together disguised as young men. In 1917, the Provisional Government raised a number of "Women's Battalions", with Bochkareva given an officer's commission in command. They were disbanded before the end of the year. In the later Russian Civil War, they fought both for the Bolsheviks (infantry) and the White Guard.
