Input: Question: Which of the two United States regions impacted by the second largest February tornado outbreak on record has a larger population? Passage 1:The history of CBS in East Texas traces back to the sign-on of the market's first television station, KTVE (channel 32) in 1953; that station shut down due to financial problems in 1955. After KLTV (channel 7) signed on in October 1954, it carried select CBS programming as part of a shared primary affiliation with ABC and NBC (eventually becoming a full-time ABC affiliate in 1984). CBS would not have a full-time affiliate in the Tyler-Longview market until September 1984, when KLMG-TV (channel 51, now KFXK-TV) signed on the air from Longview; KLMG disaffiliated from the network in April 1991 to become the market's Fox affiliate. For the thirteen years that followed, viewers in the portion of East Texas that KFXK-TV served had to rely on cable or satellite for CBS programming. Most area cable providers imported Shreveport–Texarkana affiliate KSLA, while some cable systems in the western portion of the market carried the network's Dallas–Fort Worth affiliates (KDFW was carried from 1991 until it switched to Fox in July 1995 while affiliate-turned-O&O KTVT was then carried from that point until early 2004); cable systems in Houston County carried KBTX-TV instead.
 Passage 2:The second largest February tornado outbreak on record impacted the Gulf Coast and East Coast regions of the United States beginning on February 23. The first significant tornadoes of the outbreak moved across southeastern Louisiana and southern Mississippi that evening, leaving significant damage and three deaths. The towns of Livingston and Laplace, Louisiana sustained heavy damage from strong EF2 tornadoes, and another EF2 near Purvis, Mississippi killed one person in a mobile home. An EF3 tornado also caused major structural damage in Paincourtville, Louisiana before destroying an RV park in Convent, killing two people at that location. Three simultaneous waterspouts were observed over Lake Pontchartrain during the event as well. Later that night, a large supercell thunderstorm developed over the Gulf of Mexico and moved ashore, producing a destructive EF3 tornado in Pensacola, Florida. The tornado injured three people and destroyed homes, townhouses, apartments, and a GE warehouse.
 Passage 3:The island has been inhabited since at least 3rd century A.D. The 304-year-old Kingdom of Oʻahu was once ruled by the most ancient aliʻi in all of the Hawaiian Islands. The first great king of Oʻahu was Maʻilikūkahi, the lawmaker, who was followed by many generation of monarchs. Kualiʻi was the first of the warlike kings and so were his sons. In 1773, the throne fell upon Kahahana, the son of Elani of Ewa. In 1783, Kahekili II, King of Maui, conquered Oʻahu and deposed the reigning family and then made his son, Kalanikūpule, king of Oʻahu. Kamehameha the Great would conquer in the mountain Kalanikūpule's force in the Battle of Nuʻuanu. Kamehameha founded the Kingdom of Hawaiʻi with the conquest of Oʻahu in 1795. Hawaiʻi would not be unified until the islands of Kauaʻi and Niʻihau surrendered under King Kaumualiʻi in 1810. Kamehameha III moved his capital from Lāhainā, Maui to Honolulu, Oʻahu in 1845. ʻIolani Palace, built later by other members of the royal family, is still standing, and is the only royal palace on American soil.
