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: The attribution of the panel reflects the progression and trends of 19th and 20th-century scholarship on Early Netherlandish art. It is now thought to have been completed c. 1438–40, but there are still arguments for dates as early as 1424–29. As with the pages ascribed to Hand G in the Turin-Milan Hours manuscript, the panel was attributed to Jan's brother Hubert van Eyck in the 1875 Gemäldegalerie catalogue, and by a 1911 claim by art historian Georges Hulin de Loo. This is no longer considered credible and Hubert, today, is credited with very few works. By 1912 the painting had been definitively attributed to Jan in the museum catalogue.Attempts to date it have undergone similar shifts of opinion. In the 19th century the panel was believed to be an early work by Jan completed as early as c. 1410, although this view changed as scholarship progressed. In the early 20th century, Ludwig von Baldass placed it around 1424–29, then for a long period it was seen as originating from the early 1430s. Erwin Panofsky provided the first detailed treatise on the work and placed it around 1432–34. However, following research from Meyer Schapiro, he revised his opinion to the late 1430s in the 1953 edition of his Early Netherlandish Painting. A 1970s comparative study of van Eyck's 1437 Saint Barbara concluded that Madonna in the Church was completed after c. 1437. In the 1990s, Otto Pächt judged the work as probably a late van Eyck, given the similar treatment of an interior in the 1434 Arnolfini Portrait. In the early 21st century, Jeffrey Chipps Smith and John Oliver Hand placed it between 1426 and 1428, claiming it as perhaps the earliest extant signed work confirmed as by Jan. 
Question: What is the full name of the person who is credited with very few works?
Example Output: Hubert van Eyck.

Example Input: Passage: After busting a human trafficking ring led by Sheriff Wood, Jack Reacher returns to his old military headquarters to meet Major Susan Turner, whom he has been working with during his travels and has become his closest friend – only to learn from Colonel Sam Morgan that Turner has been accused of espionage and detained.
Turner's attorney, Colonel Bob Moorcroft, reveals that there is evidence that Turner is involved in the murders of two soldiers in Afghanistan, but Reacher believes she is being framed. Moorcroft also reveals an old acquaintance of Reacher, Candice Dutton, has filed a paternity suit against him, claiming he is the biological father of her 15-year-old daughter, Samantha Dutton. Reacher tries to reach out to Samantha, but she rebuffs him, believing he is after her biological mother due to her past as a prostitute.
Moorcroft is later killed by an unknown assassin known as the Hunter. Reacher is framed for Moorcroft's murder and arrested and transported to the prison where Turner is being detained. Two hitmen arrive to kill her, but Reacher neutralizes them, rescues her and they escape to Morgan's house, having deduced he is involved in the conspiracy, to extract information. After they leave, the Hunter, revealed to be working with Morgan, kills Morgan and frames Reacher which he learns about from a friend, Sergeant Leach, when he asks her to investigate a military contractor.
Reacher and Turner uncover surveillance pictures of Samantha and surmise she is in danger, arriving at her home to find her foster parents dead and Samantha hiding in the kitchen. Reacher and Turner decide to escort Samantha to Turner's old private school for protection, but discover that she has her mobile phone with her and that the enemy probably knows exactly where they are. They discard the phone and make a quick exit, during which Samantha steals a backpack from one of the students to use the credit cards. 
Question: What is the full name of the person that Reacher believes is being framed?
Example Output: Major Susan Turner.

Example Input: Passage: Metallica is an American heavy metal band. The band was formed in 1981 in Los Angeles, California by drummer Lars Ulrich and vocalist/guitarist James Hetfield, and has been based in San Francisco, California for most of its career. The group's fast tempos, instrumentals and aggressive musicianship made them one of the founding "big four" bands of thrash metal, alongside Megadeth, Anthrax and Slayer. Metallica's current lineup comprises founding members Hetfield and Ulrich, longtime lead guitarist Kirk Hammett and bassist Robert Trujillo. Guitarist Dave Mustaine (who went on to form Megadeth) and bassists Ron McGovney, Cliff Burton and Jason Newsted are former members of the band.
Metallica earned a growing fan base in the underground music community and won critical acclaim with its first five albums. The band's third album, Master of Puppets (1986), was described as one of the heaviest and most influential thrash metal albums; its eponymous fifth album, Metallica (1991), the band's first to root predominantly in heavy metal, appealed to a more mainstream audience, achieving substantial commercial success and selling over 16 million copies in the United States to date, making it the best-selling album of the SoundScan era. After experimenting with different genres and directions in subsequent releases, the band returned to its thrash metal roots with the release of its ninth album, Death Magnetic (2008), which drew similar praise to that of the band's earlier albums.
In 2000, Metallica led the case against the peer-to-peer file sharing service Napster, in which the band and several other artists filed lawsuits against the service for sharing their copyright-protected material without consent; after reaching a settlement, Napster became a pay-to-use service in 2003. Metallica was the subject of the acclaimed 2004 documentary film Some Kind of Monster, which documented the troubled production of the band's eighth album, St. Anger (2003), and the internal struggles within the band at the time. In 2009, Metallica was inducted into the Rock and Roll Hall of Fame. The band wrote the screenplay for and starred in the 2013 IMAX concert film Metallica: Through the Never, in which the band performed live against a fictional thriller storyline. 
Question: What were the founding "big four" bands of thrash metal?
Example Output:
Metallica.
