Input: Question: What is the name of the arena where N'Dong played home games in the NBA? Passage 1:After the Second World War the Battery was re-formed in 1955 as 20 Medium Battery as part of 21 Med Regt based at Redford Barracks, Edinburgh but deployed in the Internal Security role to Cyprus in 1956 where the Regt lost several men to the EOKA terrorists. Re-numbered again and re-rolled (a change of equipment and role) as an Amphibious Operations (AO) Battery. They were posted to Hong Kong and renamed 20 Commando (AO) Battery as part of 29 Commando Regiment. Due to the fact that only 20 and 148 Commando (AO) Battery fulfilled the AO roll there was a lot of movement between the batteries most men serving in both. The battery had absorbed 3 (AO) Troop on their move to Hong Kong and was involved in a number of operations including the Korean War and a little known operation in the Caribbean during the Cuban missile crisis. The Battery was involved in clearing Russian, American and Cuban personnel off remote Caribbean islands in the region and arrested 60 men who later turned out to be CIA operatives, causing a minor political incident. The Battery was placed into suspended animation in 1969 following the downsizing of the British Army and the reduction to one Commando Artillery Regiment, having lost out to 148 Commando (AO) Battery. Many of 20 Commando (AO) Battery's personnel ended up in 148 Battery and so did much of the battery property.
 Passage 2:The 2005–06 NBA season would be the first and only NBA season for the 28-year-old 7 ft 0 in center to play in the National Basketball Association (NBA) with the Los Angeles Clippers. During this season, N'Dong barely played any notable parts with the team, appearing in 23 games with a 7-minute per game average, starting only once for them. However, the Clippers would ultimately have a surprising season under their belt in his sole season there, making it to the Western Conference semifinals for the first time in franchise history, barely upsetting the Phoenix Suns in the process. In December 2006, he signed with the Russian club Spartak St. Petersburg. N'Dong moved to the Spanish ACB league later that season and signed with Unicaja Málaga for the 2006–07 ACB League Play-Offs to replace the injured Daniel Santiago. On July 14, 2007, he re-signed with Malaga on a one-season contract. He has also played with the Cleveland Cavaliers NBA Summer League squad in 2007.
 Passage 3:June McCarroll (June 30, 1867 – March 30, 1954) is credited by the California Department of Transportation with the idea of delineating highways with a painted line to separate lanes of highway traffic, although this claim is disputed by the Federal Highway Administration and the Michigan Department of Transportation as two Michigan men painted centerlines before her. She was born in Lewis County, New York. She was a nurse (later a physician) with the Southern Pacific Railroad in the early 20th century. According to a historic marker in Indio, California, after a near-collision in her Model T in 1917, "She personally painted the first known stripe in California on Indio Boulevard, then part of U.S. Route 99, during 1917."
