Question: 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.

In 1947, Salk became ambitious for his own lab and was granted one at the University of Pittsburgh, but the lab was smaller than he had hoped and he found the rules imposed by the university restrictive. In 1948, Harry Weaver, the director of research at the National Foundation for Infantile Paralysis, contacted Salk. He asked Salk to find out if there were more types of polio than the three then known, offering additional space, equipment and researchers. For the first year he gathered supplies and researchers including Julius Youngner, Byron Bennett, L. James Lewis, and secretary Lorraine Friedman joined Salk's team, as well. As time went on, Salk began securing grants from the Mellon family and was able to build a working virology laboratory. He later joined the National Foundation for Infantile Paralysis's polio project established by President Franklin D. Roosevelt.  Extensive publicity and fear of polio led to much increased funding, $67 million by 1955, but research continued on dangerous live vaccines. Salk decided to use the safer 'killed' virus, instead of weakened forms of strains of polio viruses like the ones used contemporarily by Albert Sabin, who was developing an oral vaccine. After successful tests on laboratory animals, on July 2, 1952, assisted by the staff at the D.T. Watson Home for Crippled Children, Salk injected 43 children with his killed-virus vaccine. A few weeks later, Salk injected children at the Polk State School for the retarded and feeble-minded. In 1954 he tested the vaccine on about one million children, known as the polio pioneers. The vaccine was announced as safe on April 12, 1955.  The project became large, involving 100 million contributors to the March of Dimes, and 7 million volunteers. The foundation allowed itself to go into debt to finance the final research required to develop the Salk vaccine. Salk worked incessantly for two and a half years.  Salk's inactivated polio vaccine was the first vaccine for the disease; it came into use in 1955. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.

Question: Khloe Alexandra Kardashian was born in Los Angeles, California on June 27, 1984, to Robert, an attorney, and Kris (nee Houghton), a homemaker. She has two older sisters Kourtney and Kim, and a younger brother Rob. Their mother is of Dutch, English, Irish and Scottish ancestry, while their father was a third-generation Armenian American. After their parents divorced in 1991, Houghton remarried the 1976 Summer Olympics decathlon winner Caitlyn Jenner (then Bruce) in 1991.

In 2001, Kardashian suffered a traumatic brain injury in a car accident. She went through the windscreen and suffered a severe concussion, causing long-term memory loss.  On September 27, 2009, Kardashian married NBA basketball player Lamar Odom, who was a member of the Los Angeles Lakers at the time. The couple were married exactly one month after they met at a party for Odom's teammate Metta World Peace. Following her marriage, Kardashian removed her middle name to include her married surname, becoming Khloe Kardashian Odom. Kardashian adopted a pet boxer named Bernard "BHops" Hopkins, after the famous boxer.  On December 13, 2013, after months of speculated separation, Kardashian filed for divorce from Odom and for legal restoration of her last name. Divorce papers were signed by both parties in July 2015; however, the divorce had yet to receive final approval from a judge. In October 2015, Odom was hospitalized after being found unconscious in a Nevada brothel, and was in a coma for four days; as he lay in a hospital, Kardashian withdrew her pending divorce petition. In an interview with People Magazine, Kardashian confirmed that they had not reconciled and the divorce had been withdrawn so that she might make medical decisions on Odom's behalf. Kardashian and Odom's divorce was finalized in December 2016.  Kardashian is currently in a relationship with basketball player Tristan Thompson. The couple resides in Cleveland, Ohio. In December 2017, she announced she was expecting their first child together. In the March 2018 she revealed she will be having a girl.  Kardashian supports the recognization of the Armenian Genocide and has visited the memorial of the victims in Yerevan, Armenia. In April 2015, Kardashian accompanied her sister, Kim, and brother-in-law, Kanye West, to Jerusalem for the baptism of her niece, North, in the Armenian Apostolic Church at the Cathedral of St. James. She was named North's godmother during the ceremony.
