Q: Question: How many plays did MacQueen-Pope's former employer, who MacQueen-Pope was a private secretary for, write? Passage 1:On July 10, 1961, Shehan returned to Baltimore as its Coadjutor Archbishop (with right of succession) and Titular Archbishop of Nicopolis ad Nestum. He succeeded Francis Patrick Keough as Archbishop of Baltimore on December 8 of that same year. In this position, he led the nation's first diocese and held precedence, except for Cardinals created earlier and without the honorary title of primacy, over the Church in America. After the Supreme Court ruled to remove prayer from public schools in 1962, Shehan warned that "secularization threatens to become a sort of state religion established by court decree". He was also a strong advocate of civil rights, banning segregation in all of Baltimore's Catholic institutions and walking in the March on Washington for Jobs and Freedom in 1963. He also maintained relations with Judaism and Eastern Orthodoxy. Cardinal Shehan worked with his friend Harry Lee Doll, Episcopal Bishop of Maryland and President of the Maryland Council of Churches on both civil rights and ecumenical issues. Along with the President of St. Mary's Seminary and University, Cardinal Shehan and Bishop Doll in 1968 founded Baltimore's Ecumenical Institute, in the city's Roland Park neighborhood.
 Passage 2:Antoni Chruściel was born on 16 July 1895 in the village of Gniewczyna Łańcucka halfway between Łańcut and Przeworsk, to Andrzej Chruściel, a local farmer and the vogt of that village. In 1909, while still a student at a local gymnasium in Jarosław, Chruściel joined the secret scouting troop; he was also active in the Zarzewie movement. In 1914, after the outbreak of the First World War he moved to Lwów, where he joined the Eastern Legion. Soon afterwards, as a citizen of Austria-Hungary, he was drafted into the Austro-Hungarian Army. After graduating from an NCO school in May 1915 he served at various posts, including his service as a commanding officer of a company of the 90th Infantry Regiment. After the dissolution of Austria-Hungary and the chaos at the eastern front, Chruściel's regiment was the only unit in the entire Austro-Hungarian Army to return to the barracks as an organized entity and with arms. Few weeks later Chruściel, together with most of his unit, joined the newly formed Polish Army.
 Passage 3:MacQueen-Pope, always known by his initials or, familiarly, as "Popie", was the eldest son of Walter George Pope and Frederica MacQueen. He was educated privately and at Tollington School. He first worked in a shipping office but became connected with the theatre as private secretary to George Dance, the playwright, manager and theatrical philanthropist. He tried his hand as a playwright, with limited success: The Times was dismissive of his short play, The Punctual Sex, in 1919. Sir Alfred Butt appointed him business manager at the Queen's Theatre, and after holding similar posts at other West End theatres, and holding the post of manager and secretary of Alexandra Palace from 1922 to 1925, he was appointed general manager of the Duke of York's Theatre in 1927, and was put in charge of the new Whitehall Theatre before it opened in 1930. The Times said of his career, "it was as press representative at the Palladium in 1925 that he began to develop his special talent for passing on to others ... his love and knowledge of the theatre generally and in particular of Drury Lane, of the Haymarket (Theatre of Perfection) and of the Gaiety (Theatre of Enchantment)."
