You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Joseph Bolitho Johns, better known as Moondyne Joe, was Western Australia's best known bushranger. In July 1865, Johns was sentenced to ten years penal servitude for killing a steer.  He and another prisoner absconded from a work party in early November, and were on the run for nearly a month, during which time Johns adopted the nickname Moondyne Joe. For absconding and for being in possession of a firearm, Moondyne Joe was sentenced to twelve months in irons, and transferred to Fremantle Prison. In July 1866 he received a further six months in irons for trying to cut the lock out of his door, but in August Moondyne Joe succeeded in escaping again. Moondyne Joe formulated a plan to escape the colony by travelling overland to South Australia, but was captured on 29 September about 300 kilometres (190 mi) north-east of Perth.As punishment for escaping and for the robberies committed while on the run, Moondyne Joe received five years hard labour on top of his remaining sentence.  Extraordinary measures were taken to ensure that he did not escape again. He was transferred to Fremantle Prison where a special "escape-proof" cell was made for him, built from stone, lined with jarrah sleepers and over 1000 nails. In early 1867 Moondyne Joe was set to work breaking stone, but rather than permit him to leave the prison, the acting comptroller-general ordered that the stone be brought in and dumped in a corner of the prison yard, where Moondyne Joe worked under the constant supervision of a warder.
Governor John Hampton was so confident of the arrangements, he was heard to say to Moondyne Joe: "If you get out again, I'll forgive you". However, the rock broken by Moondyne Joe was not removed regularly, and eventually a pile grew up until it obscured the guard's view of him below the waist. Partially hidden behind the pile of rocks, he occasionally swung his sledgehammer at the limestone wall of the prison. On 7 March 1867, Moondyne Joe escaped through a hole he had made in the prison wall. A few days before the second anniversary of his escape, Moondyne Joe was recaptured, returned to prison, and sentenced to an additional four years in irons. Eventually, Governor Frederick Weld heard of his predecessor Hampton's promise, and decided that further punishment would be unfair. Moondyne Joe was given a ticket of leave in May 1871.
Output:
In what year did Joseph Bolitho Johns escape from prison for the second time?
