In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: Passage: Following the Seven Years' War (1756–63) and the forced migration of Native American tribes westward, German, Scots-Irish, and other European immigrants settled in the central Susquehanna Valley, including in the area that would become Northumberland, Pennsylvania. Northumberland was laid out around a central village green in 1772, on land originally purchased from the Iroquois by the Province of Pennsylvania in 1768, as part of the first Treaty of Fort Stanwix. During the American Revolution, the village was evacuated as part of the Big Runaway in 1778, and only finally resettled in 1784. In 1794, when the Priestleys moved there, it included Quaker and Wesleyan meeting houses, a brewery, two potteries, a potash manufacturer, a clock maker, a printer (who issued a weekly newspaper), several stores, and approximately one hundred houses.
The Priestley property, purchased in 1794 at a total cost of £500 (£ 56,400 in 2019) from Reuben Haines, who had secured the patent to the land for Northumberland, comprised four lots of the original village plan (numbers 29–32). Currently, the house and grounds occupy 1 acre (4,000 m²) at 472 Priestley Avenue. (The address of the house was originally "North Way", but the street was later renamed in honor of Joseph Priestley.) This street forms the northwest boundary of the property; the other boundaries are Hanover Avenue to the northeast, Wallis Street to the southwest, and the North Shore Railroad to the southeast. Beyond the railroad line is a baseball field, and beyond that lies the Susquehanna River, which was the original southeastern boundary of the property. The confluence of the West Branch Susquehanna River with the main (or North) branch of the Susquehanna is a short distance southwest of the property, which is at an elevation of 456 feet (139 m).The property's original area was 2 acres (8,000 m²), but this was reduced by about half around 1830 when the Pennsylvania Canal (North Branch Division) was dug through the house's front yard, between the house and river. On May 31, 1860, the Lackawanna and Bloomsburg Railroad opened with a train from Danville. This was the second railroad track in Northumberland, and ran behind the house. The canal closed in 1902 and was later filled in. The modern railroad line approximates the canal's course through the front yard; the track behind the house no longer exists. 
Question: What was reduced from 2 acres to 1 when the Pennsylvania Canal was dug?
Example Output: The Priestley property.

Example Input: Passage: Chrismansyah Rahadi ([xrisˈmanʃah raˈhadi]; 16 September 1949 – 30 March 2007), born Christian Rahadi but better known by his stage name of Chrisye ([xəˈriʃə]), was an Indonesian progressive pop singer and songwriter. In his 40-year career he won many awards and accolades; in 2011 Rolling Stone Indonesia declared him the third-greatest Indonesian musician of all time.
Born in Jakarta of mixed Chinese-Indonesian descent, Chrisye became interested in music at an early age. At high school he played bass guitar in a band he formed with his brother, Joris. In the late 1960s he joined Sabda Nada (later Gipsy), a band led by his neighbours, the Nasutions. In 1973, after a short hiatus, he rejoined the band to play in New York for a year. He briefly returned to Indonesia and then went back to New York with another band, the Pro's. After once again returning to Indonesia, he collaborated with Gipsy and Guruh Sukarnoputra to record the 1976 indie album Guruh Gipsy.
Following the success of Guruh Gipsy, in 1977 Chrisye recorded two of his most critically acclaimed works: "Lilin-Lilin Kecil" by James F. Sundah, which eventually became his signature song, and the soundtrack album Badai Pasti Berlalu. Their success landed him a recording contract with Musica Studios, with whom he released his first solo album, Sabda Alam, in 1978. Over his almost 25-year career with Musica he recorded a further eighteen albums, and in 1980 acted in a film, Seindah Rembulan. Chrisye died in his Jakarta home on 30 March 2007 after a long battle with lung cancer.
Known for his stiff stage persona and smooth vocals, Chrisye was critically acclaimed in Indonesia. Five albums to which he contributed were included in Rolling Stone Indonesia's list of the 150 Best Indonesian Albums of All Time; another four of his songs (and a fifth to which he contributed) were classified as some of the best Indonesian songs of all time in a later issue of the same magazine. Several of his albums received certification of silver or gold. He received two lifetime achievement awards, one in 1993 from the BASF Awards and another posthumously in 2007 from Indonesian television station SCTV. 
Question: What is the stage name of the person who joined Sabda Nada in the late 1960s?
Example Output: Chrisye.

Example Input: Passage: Stereolab introduced easy-listening elements into their sound with the EP Space Age Bachelor Pad Music, released in March 1993. The work raised the band's profile and landed them a major-label American record deal with Elektra Records. Their first album under Elektra, Transient Random-Noise Bursts with Announcements (August 1993), was an underground success in both the US and the UK. Mark Jenkins commented in Washington Post that with the album, Stereolab "continues the glorious drones of [their] indie work, giving celestial sweep to [their] garage-rock organ pumping and rhythm-guitar strumming". In the UK, the album was released on Duophonic Ultra High Frequency Disks, which is responsible for domestic releases of Stereolab's major albums.In January 1994, Stereolab achieved their first chart entry when the 1993 EP Jenny Ondioline, entered at number 75 on the UK Singles Chart. (Over the next three years, four more releases by the band would appear on this chart, ending with the EP Miss Modular in 1997.) Their third album, Mars Audiac Quintet, was released in August 1994. The album contains the single "Ping Pong", which gained press coverage for its allegedly explicit Marxist lyrics. The band focused more on pop and less on rock, resulting in what AllMusic described as "what may be the group's most accessible, tightly-written album". It was the last album to feature O'Hagan as a full-time member. He would continue to make guest appearances on later releases. The group issued an EP titled Music for the Amorphous Body Study Center in April 1995. The EP was their musical contribution to an interactive art exhibit put on in collaboration with New York City artist Charles Long. Their second compilation of rarities, titled Refried Ectoplasm (Switched On, Vol. 2), was released in July 1995. 
Question: What was the last album to feature O'Hagan as a full-time member?
Example Output:
Mars Audiac Quintet.
