Problem: Cheryl Ann Tweedy was born in Newcastle upon Tyne on 30 June 1983, and grew up on council estates in the suburbs of Walker and Heaton. She is the fourth of five children of Joan Callaghan, and the first of her two children with Garry Tweedy following the collapse of her marriage to the father of her three other children. Cheryl's parents were together for more than a decade but never married; they separated when she was eleven years old. At the age of seven, Cheryl appeared in a television advert for British Gas.

In 2014, Cheryl returned as a judge on the UK version of The X Factor for its eleventh series, signing a PS1.5 million contract. She was joined by Simon Cowell, Louis Walsh and Mel B on the judging panel. She was again selected to mentor the girls category, and she chose Chloe Jasmine, Stephanie Nala, Lauren Platt and Lola Saunders for the live shows. Nala and Jasmine were eliminated in week 2 and Saunders in week 4, while Platt finished fourth. In 2015, Cheryl returned to The X Factor for its twelfth series; she was joined by Cowell and new judges Rita Ora and Nick Grimshaw. She was selected to mentor the groups category for the first time and chose 4th Impact, Alien Uncovered and Reggie 'n' Bollie for the live shows. Alien Uncovered were eliminated in week 1, while 4th Impact and Reggie 'n' Bollie finished in fifth and second place, respectively. Cheryl confirmed her departure from The X Factor in April 2016, choosing to focus on her music career. On 2 June 2014, she debuted the first single from her fourth studio album Only Human, "Crazy Stupid Love", which features Tinie Tempah. Later in the month, she performed at Capital FM's Summertime Ball at Wembley Stadium. On 27 July, "Crazy Stupid Love" entered the UK Singles Chart at number one, selling 118,000 copies. It became her fourth number one single on the chart, making her the third British female artist to achieve four numbers ones as a solo artist, after Geri Halliwell and Rita Ora. The song also peaked at number one in Ireland. The second single from Only Human, "I Don't Care", was released on 2 November and similarly to its predecessor debuted at number one in the UK, becoming her fifth number one in the country. This made her the first British female to have five solo number one singles in the UK. Only Human was released on 10 November and became her fourth solo album to debut within the top 10 in the United Kingdom and Ireland. It was later certified silver in the UK. The album's title track was chosen as its third single. The song, which originally peaked at number 70 as an album cut in October 2014, failed to reach the top 100 on the UK Singles Chart upon the single's release, therefore becoming her lowest-charting single to date. In 2015, Cheryl announced she was working on her fifth studio album, initially due for release in 2016.

Problem: Popol Vuh (also Popol Wuj) is a cultural narrative that recounts the mythology and history of the K'iche' people who inhabit the Guatemalan Highlands northwest of present-day Guatemala City. The Popol Vuh is a creation narrative written by the K'iche' people before the Spanish conquest of Guatemala, originally preserved through oral tradition until approximately 1550 when it was written down. The survival of the Popol Vuh is credited to the 18th century Dominican friar Francisco Ximenez who made a copy of the original text in Spanish The name "Popol Vuh" translates as "Book of the Community", "Book of Counsel", or more literally as "Book of the People". The Popol Vuh includes the Mayan creation myth, beginning with the exploits of the Hero Twins Hunahpu and Xbalanque.

Since its rediscovery by Europeans in the 19th century, the Popol Vuh has attracted the attention of many authors. For example, the myths and legends included in Louis L'Amour's novel The Haunted Mesa are largely based on the Popol Vuh. The planet of Camazotz in Madeleine L'Engle's A Wrinkle in Time is named for the bat-god of the hero-twins story. The text was also used by German film director Werner Herzog as extensive narration for the first chapter of his movie Fata Morgana (released 1972). Mexican painter Diego Rivera did a series of watercolors in 1931, as illustrations for the book. In 1934, the Franco-American early avant-garde composer Edgard Varese wrote his Ecuatorial - a setting of words from the Popol Vuh for bass soloist and various instruments. The Argentinian composer Alberto Ginastera began writing his opus 44 symphonic work Popol Vuh in 1975, but left the work incomplete at his death in 1983. In Munich, Germany in 1969, keyboardist Florian Fricke--at the time ensconced in Mayan myth--formed a band named Popol Vuh with synth player Frank Fiedler and percussionist Holger Trulzsch. Their 1970 debut album, Affenstunde, reflected this spiritual connection. The band is notable especially for its extremely early experimentation with forms that became popularized through the modern electronic, new age/ambient music that was to follow years later. They also worked together with Werner Herzog for 5 of his movies. Another band by the same name, this one of Norwegian descent, formed around the same time, its name also inspired by the K'iche' writings.
