Problem: Athanasius of Alexandria:

In about 319, when Athanasius was a deacon, a presbyter named Arius came into a direct conflict with Alexander of Alexandria. It appears that Arius reproached Alexander for what he felt were misguided or heretical teachings being taught by the bishop. Arius's theological views appear to have been firmly rooted in Alexandrian Christianity, and his Christological views were certainly not radical at all. He embraced a subordinationist Christology which taught that Christ was the divine Son (Logos) of God, made, not begotten, heavily influenced by Alexandrian thinkers like Origen, and which was a common Christological view in Alexandria at the time. Support for Arius from powerful bishops like Eusebius of Caesarea and Eusebius of Nicomedia, further illustrate how Arius's subordinationist Christology was shared by other Christians in the Empire. Arius was subsequently excommunicated by Alexander, and he would begin to elicit the support of many bishops who agreed with his position.

Problem: Craig Venter and Francis Collins of the National Institute of Health jointly made the announcement of the mapping of the human genome in 2000. Upon examining the data from the genome mapping, Venter realized that although the genetic variation within the human species is on the order of 13% (instead of the previously assumed 1%), the types of variations do not support notion of genetically defined races. Venter said, "Race is a social concept. It's not a scientific one. There are no bright lines (that would stand out), if we could compare all the sequenced genomes of everyone on the planet." "When we try to apply science to try to sort out these social differences, it all falls apart."
What doesn't the genetic variation within the human species support?

Answer: notion of genetically defined races

Question: Her debut single, "Crazy in Love" was named VH1's "Greatest Song of the 2000s", NME's "Best Track of the 00s" and "Pop Song of the Century", considered by Rolling Stone to be one of the 500 greatest songs of all time, earned two Grammy Awards and is one of the best-selling singles of all time at around 8 million copies. The music video for "Single Ladies (Put a Ring on It)", which achieved fame for its intricate choreography and its deployment of jazz hands, was credited by the Toronto Star as having started the "first major dance craze of both the new millennium and the Internet", triggering a number of parodies of the dance choreography and a legion of amateur imitators on YouTube. In 2013, Drake released a single titled "Girls Love Beyonce", which featured an interpolation from Destiny Child's "Say My Name" and discussed his relationship with women. In January 2012, research scientist Bryan Lessard named Scaptia beyonceae, a species of horse fly found in Northern Queensland, Australia after Beyonce due to the fly's unique golden hairs on its abdomen. In July 2014, a Beyonce exhibit was introduced into the "Legends of Rock" section of the Rock and Roll Hall of Fame. The black leotard from the "Single Ladies" video and her outfit from the Super Bowl half time performance are among several pieces housed at the museum.

The growth in women's football has seen major competitions being launched at both national and international level mirroring the male competitions. Women's football has faced many struggles. It had a "golden age" in the United Kingdom in the early 1920s when crowds reached 50,000 at some matches; this was stopped on 5 December 1921 when England's Football Association voted to ban the game from grounds used by its member clubs. The FA's ban was rescinded in December 1969 with UEFA voting to officially recognise women's football in 1971. The FIFA Women's World Cup was inaugurated in 1991 and has been held every four years since, while women's football has been an Olympic event since 1996.
Who voted to ban women's football from its grounds in 1919?
