user: Which is the best tube line?

assistant: The London Underground has many lines that are popular for different reasons. The Victoria line is one of the fastest with the most convenient stops although it is noisy and lacks air conditioning. The Hammersmith, Metropolitan and Circle line have air conditioning making them popular in summer. Although not technically part of the London Underground, the Docklands Light Railway has a very scenic route when viewed from the front seats of the driverless trains. The Elizabeth Line is also popular, although technically not an underground line, due to it's new trains, stunning station architecture and faster routes.

Pro Kabaddi League
Main article: Pro Kabaddi League
The Pro Kabaddi League was established in 2014. The league modeled its business upon that of the Indian Premier League of Twenty20 cricket, with a large focus on marketing, the backing of local broadcaster Star Sports, and changes to the sport's rules and its presentation to make it more suitable for a television audience. The Pro Kabaddi League quickly became a ratings success on Indian television; the 2014 season was watched by at least 435 million viewers over the course of the season, and the inaugural championship match was seen by 98.6 million viewers.

Additional rules are used in the Pro Kabaddi League to encourage scoring: when a defensive side has three or fewer players remaining, tackles are worth two points instead of one. Furthermore, if a team performs two empty raids in a row, the next raider must score a point, or else they will be declared out and the opposing team will score a point.</think>

Central America (Spanish: América Central [aˈmeɾika senˈtɾal] (listen) or Centroamérica [sentɾoaˈmeɾika] (listen)) is a subregion of the Americas. Its boundaries are defined as bordering Mexico to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America usually consists of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage.</think>
