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.

Passage: Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago.  Whales consist of eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the grey whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales).
Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on. They use their throat pleats to expand the mouth to take in huge gulps of water. Balaenids have heads that can make up 40% of their body mass to take in water. Toothed whales, on the other hand, have conical teeth adapted to catching fish or squid. Baleen whales have a well developed sense of "smell", whereas toothed whales have well-developed hearing − their hearing, that is adapted for both air and water, is so well developed that some can survive even if they are blind. Some species, such as sperm whales, are well adapted for diving to great depths to catch squid and other favoured prey. 
Question: What are the types of whales that use throat pleats to expand the mouth?
Baleen.

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?
The Priestley property.

Passage: Despite his experience as an addict, Frusciante does not view his drug use as a "dark period" in his life. He considers it a period of rebirth, during which he found himself and cleared his mind. Frusciante has since stopped practicing yoga, due to its effects on his back, but he still tries to meditate daily.In early 1998, the Red Hot Chili Peppers fired guitarist Dave Navarro and were on the verge of breaking up. Flea told Kiedis, "the only way I could imagine carrying on [with the Red Hot Chili Peppers] is if we got John back in the band." With Frusciante free of his addictions and ailments, Kiedis and Flea thought it was an appropriate time to invite him back. When Flea visited him at his home and asked him to rejoin the band, Frusciante began sobbing and said "nothing would make me happier in the world." With Frusciante back on guitar, the Chili Peppers began recording their next album, Californication, released in 1999. Frusciante's return restored a key component of the Chili Peppers' sound, as well as a healthy morale. He brought with him his deep devotion to music, which affected the band's recording style during the album. Frusciante has frequently stated that his work on Californication was his favorite.During the Californication world tour, Frusciante continued to compose his own songs, many of which would be released in 2001 on his third solo album To Record Only Water for Ten Days. The album was stylistically unlike his previous records, less markedly stream-of-consciousness or avant-garde. However, the lyrics were still very cryptic and its sound was notably stripped down. The songwriting and production of To Record Only Water for Ten Days were more efficient and straightforward than on his previous recordings. The album strayed from the alternative rock he had just written with the Chili Peppers on Californication, focusing more on electronic and new wave elements. In addition to his guitar work, Frusciante experimented with a variety of synthesizers, a distinctive feature of the record.In 2001, Frusciante began recording his fourth album with Red Hot Chili Peppers, By the Way (2002); he considered the time to be among the happiest in his life. He relished the chance the album gave him to "keep writing better songs". While working on By the Way, he also composed most of what would become Shadows Collide with People, as well as the songs created for the movie The Brown Bunny. His goal to improve his guitar playing on the album was largely driven by a desire to emulate guitar players such as Johnny Marr, John McGeoch and Andy Partridge. He wanted to listen to these musicians "who weren't just about technique but more about textures", or as he put it, "people who used good chords". The album marked Frusciante's shift to a more group-minded mentality within the Chili Peppers, viewing the band as a cohesive unit rather than as four separate entities. 
Question: What guitar players did Frusciante want to emulate?

Johnny Marr.
