In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.

Let me give you an example: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lo during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,

Question: How many years did the Commonwealth of England exist? Passage:After the execution of the King, a republic was declared, known as the "Commonwealth of England". The "Rump Parliament" exercised both executive and legislative powers, with a smaller Council of State also having some executive functions. Cromwell remained a member of the "Rump" and was appointed a member of the Council. In the early months after the execution of Charles I, Cromwell tried but failed to unite the original "Royal Independents" led by St John and Saye and Sele, which had fractured during 1648. Cromwell had been connected to this group since before the outbreak of civil war in 1642 and had been closely associated with them during the 1640s. However, only St John was persuaded to retain his seat in Parliament. The Royalists, meanwhile, had regrouped in Ireland, having signed a treaty with the Irish known as "Confederate Catholics". In March, Cromwell was chosen by the Rump to command a campaign against them. Preparations for an invasion of Ireland occupied Cromwell in the subsequent months. In the latter part of the 1640s, Cromwell came across political dissidence in the "New Model Army". The "Leveller" or "Agitator" movement was a political movement that emphasised popular sovereignty, extended suffrage, equality before the law, and religious tolerance. These sentiments were expressed in the manifesto "Agreement of the People" in 1647. Cromwell and the rest of the "Grandees" disagreed with these sentiments in that they gave too much freedom to the people; they believed that the vote should only extend to the landowners. In the "Putney Debates" of 1647, the two groups debated these topics in hopes of forming a new constitution for England. There were rebellions and mutinies following the debates, and in 1649, the Bishopsgate mutiny resulted in the execution of Leveller Robert Lockyer by firing squad. The next month, the Banbury mutiny occurred with similar results. Cromwell led the charge in quelling these rebellions. After quelling Leveller mutinies within the English army at Andover and Burford in May, Cromwell departed for Ireland from Bristol at the end of July.
