Problem: The Charleston-North Charleston-Summerville Metropolitan Statistical Area consists of three counties: Charleston, Berkeley, and Dorchester. As of the 2013 U.S. Census, the metropolitan statistical area had a total population of 712,239 people. North Charleston is the second-largest city in the Charleston-North Charleston-Summerville Metropolitan Statistical Area and ranks as the third-largest city in the state; Mount Pleasant and Summerville are the next-largest cities. These cities combined with other incorporated and unincorporated areas along with the city of Charleston form the Charleston-North Charleston Urban Area with a population of 548,404 as of 2010. The metropolitan statistical area also includes a separate and much smaller urban area within Berkeley County, Moncks Corner . The traditional parish system persisted until the Reconstruction Era, when counties were imposed. Nevertheless, traditional parishes still exist in various capacities, mainly as public service districts. When the city of Charleston was formed, it was defined by the limits of the Parish of St. Philip and St. Michael, now also includes parts of St. James' Parish, St. George's Parish, St. Andrew's Parish, and St. John's Parish, although the last two are mostly still incorporated rural parishes.

Problem: In the north of the region is the Sailughem Mountains, also known as Kolyvan Altai, which stretch northeast from 49 N and 86 E towards the western extremity of the Sayan Mountains in 51 60 N and 89 E. Their mean elevation is 1,500 to 1,750 m. The snow-line runs at 2,000 m on the northern side and at 2,400 m on the southern, and above it the rugged peaks tower some 1,000 m higher. Mountain passes across the range are few and difficult, the chief being the Ulan-daban at 2,827 m (2,879 m according to Kozlov), and the Chapchan-daban, at 3,217 m, in the south and north respectively. On the east and southeast this range is flanked by the great plateau of Mongolia, the transition being effected gradually by means of several minor plateaus, such as Ukok plateau (2,380 m) with Pazyryk Valley, Chuya (1,830 m), Kendykty (2,500 m), Kak plateau (2,520 m), (2,590 m), and (2,410 m).

Problem: With their loss against the Colts mathematically eliminating the Texans from the AFC South title, the Texans returned home in hopes of securing a wild card spot in the playoffs. In his first career start since the 2013 season, Case Keenum started as the team's 4th quarterback of the season. Despite driving into the redzone on their first possession, the Texans instead settled on a field goal for an early 3-0 lead. Houston kicked two more field goals before scoring a touchdown (thrown by Arian Foster) to take a halftime lead of 16-0. The Texans held on to win 25-13, keeping their playoff hopes alive. Andre Johnson had six receptions for 65 yards in the game and became the 10th player in NFL history to reach 1,000 career receptions (1,002). Johnson passed Hines Ward for ninth-most in NFL history. Kicker Randy Bullock was 6/6 on field goals during the game, for a total of 19 points.
