Pentatonix 

An a capella group that officially began their singing career after winning Season 3 of "The Sing-Off," the group consists of Scott Hoying (baritone), Kirstie Maldonado (soprano/alto), Mitch Grassi (tenor), Avi Kaplan (bass), and Kevin Olusola (beatboxing percussionist). Pentatonix derives their name from the number of members in the group and from the pentatonic scale in music theory, with the c changed to an x for stylistic purposes. The group first began with the original trio of Scott, Kirstie, and Mitch from Arlington, Texas who decided that in order to effectively compete in "The Sing-Off," they needed a bass and beatboxer. Kevin (beatbox) was found by Scott on Youtube after watching Kevin's video of him beatboxing while playing the cello. Avi (bass) was contacted by the trio and joined up after seeing the three in a Youtube video. After winning on Season 3, the group signed a record label and was soon touring the United States. Their specialty is doing covers of popular music while adding in their own special breakdowns and futuristic musical effects, thanks to Kevin and Avi, with Scott, Kirstie, and Mitch focusing on melody and harmony. Some of their most popular covers are "Video Killed the Radio Star" by the Buggles, "Dog Days Are Over" by Florence and the Machine, and "Aha!" by Imogen Heap.

Pentagon

The pentagonal building serving as the headquarters of the US Department of Defense, near Washington, DC. The Pentagon's unique shape makes it a highly efficient office building. Although the Pentagon has 3,705,793 square feet (1,129,526 meters) of office space, it is possible to reach most points in the building within 10 minutes, a remarkable architectural achievement. In a building which coordinates the armed forces of the United States along with organizations responsible for intelligence and security, workers often need to be able to access each other quickly.

The idea of the Pentagon was conceived in 1941, when Brigadier General Brehon Sommervell was trying to solve the problem of limited space for the Department of Defense, a serious issue in the Second World War. It was agreed that a new building was needed, and a groundbreaking ceremony took place on 11 September, 1941. It took just two years to complete the building on former marshlands along the outskirts of Washington, and the Pentagon was quickly filled with communications equipment and staff to coordinate the Department of Defense.
