Some context: Drazen Petrovic (pronounced [draZen petrovitc]; October 22, 1964 - June 7, 1993) was a Croatian professional basketball player. A shooting guard, he initially achieved success playing professional basketball in Europe in the 1980s, before joining the National Basketball Association (NBA) in 1989. A star on multiple stages, Petrovic earned two silver medals and one bronze in Olympic basketball, a gold and a bronze in the FIBA World Cup, a gold and a bronze in the FIBA EuroBasket, and two EuroLeague titles. He represented Yugoslavia's national team and, later, Croatia's national team.
After spending a year serving the mandatory time in the military, Petrovic followed his brother's footsteps and moved to Cibona to form, at that time, the best backcourt duo in Europe. The very first year in Cibona he won both the Yugoslav League championship and the Yugoslav National Cup. To top it all off, the 87-78 victory over the Spanish League club Real Madrid, to which Petrovic contributed with 36 points, brought him and Cibona their first European Cup title. The second came the following year, as Petrovic scored 22 points and Cibona defeated the USSR Premier League club Zalgiris Kaunas, which starred the legendary Arvydas Sabonis. The same year brought another Yugoslav national cup title for Cibona, seeing Petrovic score 46 against the old rival Bosna. In 1987, Petrovic earned his third European trophy: a 2nd-tier European Cup Winners' Cup title against the Italian League club Scavolini Pesaro, whose net he filled with 28 points.  Petrovic's scoring average during the four years with Cibona stood at 37.7 points in the Yugoslavian first division and 33.8 in all of the European wide competitions that he played in, with personal one-time bests of 112 (40/60 FG, 10/20 3Pts, 22/22 FT) in the Yugoslavian League, and 62 points in the 3rd-tier European league, the Korac Cup, respectively. His scoring sheet was often known to show 40, 50, even 60 in a single game; in a 1985-86 season European League game against Limoges, Petrovic scored ten 3-pointers, including seven in a row during a first half stretch, for a final tally of 51 points and 10 assists; the same season he scored 45 points and dished out 25 assists against the reigning Italian League champions Simac Milano.  Petrovic needed new challenges, which Cibona and the Yugoslavian League could not offer. Across the Atlantic, the Portland Trail Blazers of the NBA had already used their third round pick on young Petrovic in 1986. However, he decided to postpone his departure to the United States. In 1988, he signed with Real Madrid instead, for at that time a hefty sum of around US$4 million. The transfer wasn't without controversy as the Yugoslav sporting laws stipulated that players weren't allowed to professionally move abroad until reaching 28 years of age, while Petrovic was still only 23 when he signed with the famous Madrid club. In 2014, Jose Antonio Arizaga, the sports agent who played a key role in Petrovic's summer 1988 transfer from Cibona to Real, recalled a few details from this transaction: "I spoke to Mirko Novosel, Drazen's coach at Cibona, and he told me two things. One, every problem in Yugoslavia can be taken care of with the right amount of money, and two, if Drazen leaves, every other player under 28 will be leaving and it'll be chaos. So, you can imagine all the individuals I had to bribe and all the places where I had to pay up in order to circumvent this law".
What position did Petrovic play?
A: the best backcourt duo in Europe.
Some context: 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.
When did she pass away?
