Problem: Background: Najm was born and raised in Tallahassee, Florida. His stage name is short for "Tallahassee Pain", and was chosen because of the hardships he experienced while living there. Najm was brought up in a Muslim household, but he has expressed his lack of interest in the concept of religion. At just three years old he got his first taste of the music business when a friend of the family, gospel jazz artist/producer Ben Tankard, allowed him to spend time and "twist the knobs" at his recording studio.
Context: In mid-2006, T-Pain began work on his second album, now with the Zomba Label Group as well as Konvict Muzik and Jive Records. The album, titled Epiphany, was released on June 5, 2007. The album sold 171,000 records in its first week, reaching number one on the Billboard 200. The record has since sold 819,000 records in the United States.  The album was preceded by the lead single "Buy U a Drank (Shawty Snappin')" featuring Yung Joc in February 2007. The single reached number one on both the Hot 100 and Hot R&B/Hip-Hop Songs chart, becoming his first single to top charts. The album's second single, "Bartender", featuring Akon was released in June 2007 and reached number five on the Hot 100 and number nine on the Hot R&B/Hip-Hop Songs chart. The third and final single from the album, "Church", was released in October 2007 but failed to chart in the United States.  Speaking in May 2007 to noted UK R&B writer Pete Lewis, of the award-winning Blues & Soul about his reason for naming his second album 'Epiphany', T-Pain stated: "One of the two dictionary meanings of epiphany is 'a sudden moment of insight or revelation'. And to me the title 'Epiphany' signifies the moment I realized that, to make the best music I can, I needed to just go in the studio and be myself, and not concentrate so hard on following other people's formulas."  While promoting his second album, T-Pain made guest appearances on multiple songs by other artists. T-Pain was featured on "I'm a Flirt" (remix) by R. Kelly with T.I., "Outta My System" by Bow Wow, "Baby Don't Go" by Fabolous, "I'm So Hood" by DJ Khaled with many other rappers, "Shawty" by Plies, "Kiss Kiss" by Chris Brown, "Low" by Flo Rida, and "Good Life" by Kanye West. In two weeks in late 2007, T-Pain was featured on four top ten singles on the Billboard Hot 100 chart  "Good Life" with Kanye West later won the BET Award for Best Collaboration and was nominated in several other categories. In 2008, the single won a Grammy Award for Best Rap Song.

Problem: Background: Jonas Edward Salk (; October 28, 1914 - June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician. In 1939, after earning his medical degree, Salk began an internship as a physician scientist at Mount Sinai Hospital.
Context: After City College, Salk enrolled in New York University to study medicine. According to Oshinsky, NYU based its modest reputation on famous alumni, such as Walter Reed, who helped conquer yellow fever. Tuition was "comparatively low, better still, it did not discriminate against Jews, ... while most of the surrounding medical schools--Cornell, Columbia, University of Pennsylvania, and Yale--had rigid quotas in place." Yale, for example, accepted 76 applicants, in 1935, out of a pool of 501. Although 200 of the applicants were Jewish, only five got in. During his years at New York University Medical School, Salk worked as a laboratory technician during the school year and as a camp counselor in the summer.  During Salk's medical studies, he stood out from his peers, according to Bookchin, "not just because of his continued academic prowess--he was Alpha Omega Alpha, the Phi Beta Kappa Society of medical education--but because he had decided he did not want to practice medicine." Instead, he became absorbed in research, even taking a year off to study biochemistry. He later focused more of his studies on bacteriology which had replaced medicine as his primary interest. He said his desire was to help humankind in general rather than single patients. "It was the laboratory work, in particular, that gave new direction to his life."  According to Salk: "My intention was to go to medical school, and then become a medical scientist. I did not intend to practice medicine, although in medical school, and in my internship, I did all the things that were necessary to qualify me in that regard. I had opportunities along the way to drop the idea of medicine and go into science. At one point at the end of my first year of medical school, I received an opportunity to spend a year in research and teaching in biochemistry, which I did. And at the end of that year, I was told that I could, if I wished, switch and get a Ph.D. in biochemistry, but my preference was to stay with medicine. And, I believe that this is all linked to my original ambition, or desire, which was to be of some help to humankind, so to speak, in a larger sense than just on a one-to-one basis."  Concerning his last year of medical school Salk says: "I had an opportunity to spend time in elective periods in my last year in medical school, in a laboratory that was involved in studies on influenza. The influenza virus had just been discovered about a few years before that. And, I saw the opportunity at that time to test the question as to whether we could destroy the virus infectivity and still immunize. And so, by carefully designed experiments, we found it was possible to do so."
