Problem: Exodus is an American thrash metal band formed in 1979 in Richmond, California. The band has gone through numerous lineup changes, two extended hiatuses, and the deaths of two former band members. Their current lineup consists of guitarists Gary Holt and Lee Altus, bassist Jack Gibson, drummer Tom Hunting, and lead vocalist Steve "Zetro" Souza. Hunting is one of the original members, and departed from Exodus twice, in 1989 and 2004, but rejoined in 2007.

The initial lineup of Exodus was formed in the late 1970s by guitarists Kirk Hammett and Tim Agnello, drummer/vocalist Tom Hunting, and vocalist Keith Stewart while attending high school together. The band added bass guitarist Carlton Melson in 1980, and the quintet began making a name for themselves playing backyard parties and various school functions. They played mostly cover songs in the vein of 1970s hard rock and New wave of British heavy metal (NWOBHM) acts but also developed some of their own original songs. Things with Stewart did not work out, and Hunting became the band's sole vocalist for some time. Carlton Melson was replaced in 1981 by bass guitarist Geoff Andrews. Tim Agnello would leave the group soon after to pursue a life of ministry in Stockton, California, leaving Exodus to perform as a power trio until a replacement was found in Hammett's friend and Exodus roadie Gary Holt.  Also in 1981, Hammett met El Cerrito resident Paul Baloff at a North Berkeley house party, a friendship that was started - according to Hammett - by their shared admiration for punk rock and 1970s heavy metal music. Baloff became the band's lead vocalist and the quintet recorded a 3-track demo tape in 1982 consisting of the songs "Whipping Queen", "Death and Domination" and "Warlord", a release which would be Hammett's only recording with Exodus. The band's music began to incorporate elements of hardcore punk into their NWOBHM roots, and Exodus were considered the pioneers of the Bay Area thrash metal scene. In November 1982, Exodus opened a show at San Francisco's Old Waldorf venue for Metallica, a then-relatively unknown (and unsigned) band from Los Angeles. As the band began playing more shows in Bay Area clubs, they gained a large, fervent fan base known for their violent concert behavior.  In early 1983, Hammett left Exodus to join Metallica on the recommendation of Mark Whitaker, leaving Gary Holt to effectively take creative control of the band. Hammett was replaced short term by Mike Maung, followed by Evan McCaskey, before the band finally found a permanent replacement in guitarist Rick Hunolt. Geoff Andrews also left to start an early incarnation of pioneering death metal band Possessed, and was replaced by bass guitarist Rob McKillop.  In the spring of 1984, Exodus entered Turk Street Studios with producer Doug Piercy to record demos of songs that would later appear on their debut album. The band was signed to New York-based Torrid Records and Exodus prepared to enter Prairie Sun Recording Studios that summer.

Problem: Theodore John Kaczynski (; born May 22, 1942), also known as the Unabomber, is an American domestic terrorist. A mathematics prodigy, he abandoned an academic career in 1969 to pursue a primitive lifestyle, then between 1978 and 1995 he killed three people, and injured 23 others, in a nationwide bombing campaign targeting those involved with modern technology. In conjunction, he issued a social critique opposing industrialization and advancing a nature-centered form of anarchism.

Kaczynski was born on May 22, 1942, in Chicago, Illinois, to working-class, second-generation Polish Americans, Wanda Theresa (nee Dombek) and Theodore Richard Kaczynski. His parents told his younger brother, David Kaczynski, that Ted had been a happy baby until severe hives forced him into hospital isolation with only limited contact with others, after which he "showed little emotion for months". Wanda later recalled Ted recoiling from a picture of himself as an infant being held down by physicians examining his hives, and said he always showed sympathy to animals in cages or otherwise helpless, which she speculated stemmed from his experience in hospital isolation.  From first to fourth grade, Kaczynski attended Sherman Elementary School in Chicago, where administrators described him as "healthy" and "well-adjusted". In 1952, three years after David was born, the family moved to southwest suburban Evergreen Park, Illinois; Ted transferred to Evergreen Park Central School. After testing scored his IQ at 167, he skipped the sixth grade. Kaczynski later described this as a pivotal event: previously he had socialized with his peers and was even a leader, but after skipping ahead he felt he did not fit in with the older children and was bullied.  Neighbors in Evergreen Park later described the Kaczynskis as "civic-minded folks", one stating that the parents "sacrificed everything they had for their children". Both Ted and David were intelligent, but Ted stood out in particular. One neighbor said she had "never known anyone who had a brain like [Ted's]," while another commented that Ted was "strictly a loner" who "didn't play ... an old man before his time." His mother recalled Ted as a shy child who would become unresponsive if pressured into a social situation. At one point she was so worried about Ted's social development that she considered entering him in a study for autistic children led by Bruno Bettelheim, but decided against it after observing Bettelheim's abrupt and cold manner.

Was David his only sibling?
