Q: Question: Of the two towns that US 50 travels through before reaching the outskirts of chillicothe, which has the greater population? Passage 1:East of Milford, US 50 becomes a two-lane highway as it travels through Hillsboro and Bainbridge before reaching the outskirts of Chillicothe. In Chillicothe, US 50 becomes Western Avenue and then Main Street before merging with U.S. Route 23 and U.S. Route 35 east of the city. State Route 104 overlaps US 50 through downtown Chillicothe. As US 50 leaves Chillicothe it becomes a two-lane highway once again as it winds its way through McArthur and heavy forested Southern Ohio before reaching the outskirts of Athens where it becomes a four-lane highway. It will remain four-lane until reaching the Ohio River. US 50 joins with State Route 32 near the Ohio University Bush Airport–Snyder Field in Albany, west of Athens. US 50 intersects with U.S. Route 33 east of the city before continuing eastward toward Belpre and the Ohio River. US 50 begins to overlap SR 7 near Reedsville as it heads north along the river, and splits from SR 7 before it crosses the river on the Blennerhassett Island Bridge to Parkersburg, West Virginia.
 Passage 2:He returned to Milan in 1990, where he was a reserve in the first team's defence, behind the legendary Maldini, Baresi, Costacurta, Tassotti back-line, which is regarded by many as the sport as one of the greatest difensive line-ups of all time. He made his Milan debut on 5 September 1990, in a 1–0 home Coppa Italia victory over Triestina, as Milan went on to reach the final of the tournament. He made his Serie A debut with the club on 3 March 1991, in a 4–1 home win over Napoli. In his four non-consecutive seasons with Milan (1990–91 under Arrigo Sacchi, and 1992–995 under Fabio Capello), Nava made a total of 47 appearances in all competitions, and 21 Serie A league appearances, scoring 1 goal, which came in Serie A. During his time at the club he won two Serie A titles, three Supercoppa Italiana titles, two UEFA Super Cups, an UEFA Champions League, and an Intercontinental Cup. He spent the 1991–92 season only loan with Parma, where he won the Coppa Italia. His final appearance with Milan was in a 5–0 away victory against Brescia, during the 1994–95 Serie A season, on 5 March 1995.
 Passage 3:Zeigler was drafted in the sixth round of the 1996 NFL Draft by the Bills in 1996. He became their starting center as a sophomore in 1997, playing between left offensive guard Ruben Brown and right guard Corbin Lacina, replacing the 11-year incumbent Kent Hull. That was the final one in Marv Levy's term as head coach (6-10 won-lost record), replaced the following year by his defensive coordinator, Wade Phillips, who guided the Bills to playoff berths in 1998 and 1999. In 1998, when Zeigler started all 16 games, playing between Brown and Joe Panos, Buffalo finished in second place in the AFC East and lost a wild-card game to the Miami Dolphins. In 1999, Buffalo also finished in second place in the AFC east, but Zeigler was switched to right guard to make place for Jerry Ostroski as the center next to Brown. The Bills lost another wild-card game, this time to the Tennessee Titans.
