Problem: Given the question: Given the following context:  "Single Ladies (Put a Ring on It)" was written by Beyoncé, Terius "The-Dream" Nash, Thaddis "Kuk" Harrell, and Christopher "Tricky" Stewart, and was produced by Nash and Stewart. Beyoncé recorded the song in May 2008 at the Boom Boom Room Studio in Burbank, California, and it was mixed by Jaycen Joshua and Dave Pensado, with assistance from Randy Urbanski and Andrew Wuepper. Nash conceptualized "Single Ladies" after Beyoncé's secret marriage to hip hop recording artist Jay-Z in April 2008. Stewart commented that the song was "the only public statement that [Beyoncé and Jay-Z had] ever made about marriage", and that while in the studio recording the song Beyoncé had remained tightlipped, even to the point of removing her wedding band. Beyoncé's marriage inspired Nash to compose a song about an issue that affected many people's relationships: the fear or unwillingness of men to commit. In an interview with Billboard magazine, Beyoncé added that she was drawn to the song because of the universality of the topic, an issue that "people are passionate about and want to talk about and debate". She stated that although "Single Ladies" is a playful uptempo song, it addresses an issue that women experience every day.In "Single Ladies", Beyoncé portrays her alter ego Sasha Fierce, which appears on the second part of I Am... Sasha Fierce. The song was released simultaneously with "If I Were a Boy"; as lead singles, they were meant to demonstrate the concept of the dueling personalities of the singer. This reinforced the theme of the album, which was created by placing its ballads and uptempo tracks on separate discs. The singles debuted on US radio on October 8, 2008; "Single Ladies" did so on mainstream urban New York radio station Power 105.1. Both singles were added to rhythmic contemporary radio playlists on October 12, 2008; "Single Ladies" was sent to urban contemporary playlists the same day, while "If I Were a Boy" was instead classified for contemporary hit radio. The two songs were released as a double A-side...  answer the following question:  Whose songs were meant to demonstrate the concept of the dueling personalities?

The answer is:
Beyoncé


Problem: Given the question: Given the following context:  Desegregation in Birmingham took place slowly after the demonstrations. King and the SCLC were criticized by some for ending the campaign with promises that were too vague and "settling for a lot less than even moderate demands". In fact, Sydney Smyer, president of the Birmingham Chamber of Commerce, re-interpreted the terms of the agreement. Shuttlesworth and King had announced that desegregation would take place 90 days from May 15.  Smyer then said that a single black clerk hired 90 days from when the new city government took office would be sufficient. By July, most of the city's segregation ordinances had been overturned.  Some of the lunch counters in department stores complied with the new rules. City parks and golf courses were opened again to black and white citizens.  Mayor Boutwell appointed a biracial committee to discuss further changes.  However, no hiring of black clerks, police officers, and firefighters had yet been completed and the Birmingham Bar Association rejected membership by black attorneys.The reputation of Martin Luther King Jr. soared after the protests in Birmingham, and he was lauded by many as a hero. The SCLC was much in demand to effect change in many Southern cities. In the summer of 1963, King led the March on Washington for Jobs and Freedom where he delivered his most famous speech, "I Have a Dream". King became Time's Man of the Year for 1963 and won the Nobel Peace Prize in 1964. Four months after the Birmingham campaign settlement, someone bombed the house of NAACP attorney Arthur Shores, injuring his wife in the attack. On September 15, 1963, Birmingham again earned international attention when Ku Klux Klan members bombed the 16th Street Baptist Church on a Sunday morning and killed four young girls.  FBI informant Gary Thomas Rowe was hired to infiltrate the KKK and monitor their activities and plans. Rowe was involved, along with the Birmingham Police, with the KKK attacks on the Freedom Riders, led by Fred Shuttlesworth, in Anniston, Alabama on May 14, 1961. In...  answer the following question:  What is the first name of the person who announced, with Shuttlesworth, that desegregation would take place 90 days from May 15?
