Example Input: Passage: As part of the RAAF's reorganisation following the outbreak of World War II in September 1939, No. 2 Group was formed in Sydney on 20 November; Charlesworth was appointed its Senior Air Staff Officer (SASO). He continued to serve in this position when the group was re-formed as Central Area in March 1940. Posted to Western Australia to take command of RAAF Station Pearce in August, he was promoted to temporary group captain on 1 September 1940. He became Senior Administration Officer at the newly established Western Area, Perth, in January the following year. In September 1942, Charlesworth took over No. 2 Bombing and Gunnery School in Sale, Victoria. He handed over to Group Captain Charles "Moth" Eaton in August 1943, before briefly taking charge of RAAF Headquarters Forward Echelon in Brisbane. Charlesworth was appointed Air Officer Commanding (AOC) Eastern Area, headquartered at Bradfield Park, Sydney, in December 1943. Eastern Area was responsible for maritime patrol and anti-submarine warfare off the coast of New South Wales and southern Queensland. Japanese submarine activity had decreased in the months prior to Charlesworth taking command, and he was concerned that Allied ships were becoming complacent. He observed "a general slackening off in procedure; ships are seldom where they should be, and a minority of merchant ships identify themselves to aircraft". The RAAF's patrols had also settled into a predictable pattern that would have been easy for an observant submarine captain to avoid.

Example Input: Passage: The construction of the cathedral was approved in 1894 by the Ministry of Internal Affairs under Tsarist Russia. Groundbreaking was in 1899; construction work began in 1901 and was completed ten years later. Three-aisled and built from red brick, the cathedral is based on a design by architect Tomasz Bohdanowicz-Dworzecki. The style was influenced by Westminster Abbey and Milan Cathedral. With the help of funds from Catholic parishes in Russia and its neighbouring states, the church was consecrated as a chapel for Moscow's Polish parish in 1911. In the aftermath of the Russian Revolution in 1917, the Provisional Government was overthrown by the Bolsheviks and Russia eventually became part of the Soviet Union in 1922. Because the promotion of state atheism was a part of Marxist–Leninist ideology, the government ordered many churches closed; the cathedral was closed in 1938. During World War II, it was threatened with demolition, and was used after the war for civil purposes, as a warehouse and then a hostel. Following the fall of communism in 1991, it returned to being a church in 1996. In 2002 it was elevated to the status of cathedral. Following an extensive and costly programme of reconstruction and refurbishment, the cathedral was reconsecrated in 2005.
