Problem: Edward Rickenbacker was born in Columbus, Ohio, to Swiss German-speaking immigrants. From childhood, he loved machines and experimented with them, encouraged by his father's words: "A machine has to have a purpose". In what was to become one of the defining characteristics of Rickenbacker's life, he nearly died many times in events ranging from an early run-in with a horse-drawn carriage, to a botched tonsillectomy, to airplane crashes. His first life-threatening experience occurred when he was in the "Horsehead Gang".

Rickenbacker wanted to join the Allied troops in World War I, but the U.S. had not yet entered the war. He had several chance encounters with aviators, including a fortuitous incident in which he repaired a stranded aircraft for Townsend F. Dodd, a man who later became General John J. Pershing's aviation officer and an important contact in Rickenbacker's attempt to join air combat. During World War I, with its anti-German atmosphere, he -- like many other German Americans -- changed his surname; the "h" in "Rickenbacher" became a "k" in an effort to "take the Hun out of his name." As he was already well known at the time, the change received wide publicity. "From then on", as he wrote in his autobiography, "most Rickenbachers were practically forced to spell their name in the way I had..." He believed his given name "looked a little plain." He signed his name 26 times, with a different middle initial each time. After settling upon "V", he selected "Vernon" as a middle name. In 1916, Rickenbacker traveled to London, with the aim of developing an English car for American races. Because of an erroneous press story and Rickenbacker's known Swiss heritage, he was suspected of being a spy. En route and in England, agents closely monitored his actions. On a sea voyage back to America, he came up with the idea to recruit his race car driver friends as fighter pilots, on the theory that such men were accustomed to tight spaces and high speeds. His suggestion was ignored by the military.

Problem: Henrietta Lacks (born Loretta Pleasant; August 1, 1920 - October 4, 1951) was an African-American woman whose cancer cells are the source of the HeLa cell line, the first immortalized cell line and one of the most important cell lines in medical research. An immortalized cell line will reproduce indefinitely under specific conditions, and the HeLa cell line continues to be a source of invaluable medical data to the present day. Lacks was the unwitting source of these cells from a tumor biopsied during treatment for cervical cancer at Johns Hopkins Hospital in Baltimore, Maryland, U.S., in 1951. These cells were then cultured by George Otto Gey who created the cell line known as HeLa, which is still used for medical research.

Henrietta Lacks was born Loretta Pleasant on August 1, 1920, in Roanoke, Virginia, to Eliza and Johnny Pleasant. Her family is uncertain how her name changed from Loretta to Henrietta, but she was nicknamed Hennie. When Lacks was four years old in 1924, her mother died giving birth to her tenth child. Unable to care for the children alone after his wife's death, Lacks' father moved the family to Clover, Virginia, where the children were distributed among relatives. Lacks ended up with her grandfather, Tommy Lacks, in a two-story log cabin that was once the slave quarters on the plantation that had been owned by Henrietta's white great-grandfather and great-uncle. She shared a room with her nine-year-old cousin and future husband, David "Day" Lacks (1915-2002). Like most members of her family living in Clover, Lacks worked as a tobacco farmer starting from an early age. In 1935, when Lacks was 14 years old, she gave birth to a son, Lawrence Lacks. In 1939, her daughter Elsie Lacks (1939-1955) was born. Both children were fathered by Day Lacks. Elsie Lacks had developmental disabilities and was described by the family as "different" or "deaf and dumb". On April 10, 1941, Day and Henrietta Lacks were married in Halifax County, Virginia. Later that year, their cousin, Fred Garrett, convinced the couple to leave the tobacco farm in Virginia and move to Maryland where Day Lacks could work at Bethlehem Steel in Sparrow's Point. Not long after they moved to Maryland, Garrett was called to fight in World War II. With the savings gifted to him by Garrett, Day Lacks was able to purchase a house at 713 New Pittsburgh Avenue in Turner Station. Now part of Dundalk, Turner Station was one of the oldest and largest African-American communities in Baltimore County at that time. Living in Maryland, Henrietta and Day Lacks had three more children: David "Sonny" Lacks Jr. (b. 1947), Deborah Lacks Pullum (born Deborah Lacks; 1949-2009), and Joseph Lacks (1950). Henrietta gave birth to her last child at the Johns Hopkins Hospital in Baltimore in November 1950, four and a half months before she was diagnosed with cervical cancer. Around the same time, Elsie Lacks (Henrietta and Day's daughter born in 1939), was placed in the Hospital for the Negro Insane, later renamed Crownsville Hospital Center, where Elsie died in 1955.

Problem: Gwen Renee Stefani (; born October 3, 1969) is an American singer, songwriter, fashion designer, and actress. She is a co-founder and the lead vocalist of the band No Doubt that experienced major success after their breakthrough studio album Tragic Kingdom (1995) along with various successful singles, including "Just a Girl"

Stefani made most of the clothing that she wore on stage with No Doubt, resulting in increasingly eclectic combinations. Stylist Andrea Lieberman introduced her to haute couture clothing, which led to Stefani launching a fashion line named L.A.M.B. in 2004. The line takes influence from a variety of fashions, including Guatemalan, Japanese, and Jamaican styles. The line achieved popularity among celebrities and is worn by stars such as Teri Hatcher, Nicole Kidman, and Stefani herself. In June 2005, she expanded her collection with the less expensive Harajuku Lovers line, which she referred to as "a glorified merchandise line", with varied products including a camera, mobile phone charms, and undergarments. In late 2006, Stefani released a limited edition line of dolls called "Love. Angel. Music. Baby. Fashion dolls". The dolls are inspired by the various fashion that Stefani and the Harajuku Girls wore while touring for the album. In late summer 2007, Stefani launched a perfume, L, as a part of her L.A.M.B. collection of clothing and accessories. The perfume has high notes of sweet pea and rose. In September 2008, Stefani released a fragrance line as a part of her Harajuku Lovers product line. There are five different fragrances based on the four Harajuku Girls and Stefani herself called Love, Lil' Angel, Music, Baby and G (Gwen). As of January 2011, Stefani has become the spokesperson for L'Oreal Paris. In 2016, Urban Decay released a limited edition cosmetic collection in collaboration with Stefani. In 2014, Stefani announced the production of an animated series about her and the Harajuku Girls. Along with Vision Animation and Moody Street Kids, Stefani has helped create the show which features her, Love, Angel, Music, and Baby as the band, HJ5, who fight evil whilst trying to pursue their music career. Mattel have signed on as the global toy licensee and the series itself, Kuu Kuu Harajuku will be distributed worldwide by DHX Media.
