Question: What is the population difference between the place where Atkinson visited his parents in 1975 and the place where he found a job with The Morning Sun Newspaper? Passage:While visiting his parents for Christmas at Fort Riley, Kansas, in 1975, Atkinson found a job as a newspaper reporter for The Morning Sun in Pittsburg, Kansas, covering crime, local government, and other topics in southeast Kansas, an area known as “the Little Balkans” for its ethnic diversity and fractious politics. In April 1977, he joined the staff of The Kansas City Times, working nights in suburban Johnson County, Kansas, before moving to the city desk and eventually serving as a national reporter; in 1981, he joined the newspaper's bureau in Washington, D.C. He won the Pulitzer Prize for national reporting in 1982 for a "body of work" that included a series about the West Point class of 1966, which lost more men in Vietnam than any other Military Academy class. He also contributed to the newspaper's coverage of the Hyatt Regency walkway collapse in Kansas City, Missouri, for which the paper's staff in 1982 was awarded a Pulitzer Prize for local spot news reporting.

Question: In what countries are the headquarters of the churches that venerate Mari as a saint? Passage:Saint Mari, also known as Mares and originally named Palut, is a saint of the Church of the East. He was converted by Thaddeus of Edessa (a.k.a. Addai) and is said to have had Mar Aggai as his spiritual director. He is believed to have done missionary work around Nineveh, Nisibis, and along the Euphrates, and is said to have been one of the great apostles to Syria and Persia. He was buried in Dair-Kuni. His feast day is 5 August in the Christian calendar. He and Thaddeus are credited with the Liturgy of Addai and Mari. Despite the fact that there is little, if any, concrete information on Mari, he is still venerated as a saint by the Assyrian Church of the East, the Chaldean Catholic Church, the Roman Catholic Church, and the Syro-Malabar Catholic Church. He is distinct from St Mari of the seventy disciples with whom the Apocryphal Acts of Mar Mari are connected.
