Question: How deep were their heavy infantry formations normally? Passage:Having recovered from their losses at Trebia (218 BC) and Lake Trasimene (217 BC), the Romans decided to engage Hannibal at Cannae, with approximately 86,000 Roman and allied troops. They massed their heavy infantry in a deeper formation than usual, while Hannibal used the double envelopment tactic and surrounded his enemy, trapping the majority of the Roman army, who were then slaughtered. The loss of life on the Roman side was one of the most lethal single day's fighting in history; Adrian Goldsworthy equates the death toll at Cannae to "the massed slaughter of the British Army on the first day of the Somme offensive in 1916." Only about 15,000 Romans, most of whom were from the garrisons of the camps and had not taken part in the battle, escaped death. Following the defeat, Capua and several other Italian city-states defected from the Roman Republic to Carthage.

Question: Which of the teams Rasheed Wallace played for in the 2003-04 season had the most wins overall? Passage:The 2003–04 NBA season was the 34th season for the Portland Trail Blazers in the National Basketball Association. After years of off the court troubles and playoff underachieving, the Blazers under new General Manager John Nash, decided to rebuild. Throughout the season, the Blazers dealt away talented but troubled stars like trading Bonzi Wells, after losing his co-captain title, to the Memphis Grizzlies in November, and trading Rasheed Wallace to the Atlanta Hawks for Shareef Abdur-Rahim and Theo Ratliff in February. However, after appearing in only one game with the Hawks, Sheed was again traded to the Detroit Pistons for the rest of the season. The Pistons would eventually win the NBA Finals of that year, giving Wallace his first championship. The team also sent Jeff McInnis to the Cleveland Cavaliers for Darius Miles.
