Task: Question Generation
Input (English): Passage: Martin Luther King Jr.'s presence in Birmingham was not welcomed by all in the black community.  A local black attorney complained in Time that the new city administration did not have enough time to confer with the various groups invested in changing the city's segregation policies. Black hotel owner A. G. Gaston agreed. A white Jesuit priest assisting in desegregation negotiations attested the "demonstrations [were] poorly timed and misdirected".Protest organizers knew they would meet with violence from the Birmingham Police Department and chose a confrontational approach to get the attention of the federal government. Wyatt Tee Walker, one of the SCLC founders and the executive director from 1960 to 1964, planned the tactics of the direct action protests, specifically targeting Bull Connor's tendency to react to demonstrations with violence: "My theory was that if we mounted a strong nonviolent movement, the opposition would surely do something to attract the media, and in turn induce national sympathy and attention to the everyday segregated circumstance of a person living in the Deep South." He headed the planning of what he called Project C, which stood for "confrontation". Organizers believed their phones were tapped, so to prevent their plans from being leaked and perhaps influencing the mayoral election, they used code words for demonstrations.The plan called for direct nonviolent action to attract media attention to "the biggest and baddest city of the South". In preparation for the protests, Walker timed the walking distance from the 16th Street Baptist Church, headquarters for the campaign, to the downtown area. He surveyed the segregated lunch counters of department stores, and listed federal buildings as secondary targets should police block the protesters' entrance into primary targets such as stores, libraries, and all-white churches.
Output (English): What is the last name of the person who surveyed segregated lunch counters?
