TASK DEFINITION: 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.
PROBLEM: Passage: Hilda Rix Nicholas (née Rix, later Wright, 1 September 1884 – 3 August 1961) was an Australian artist. Hilda Rix was born in the Victorian city of Ballarat. Her father was an education administrator and poet, her mother was a musician and artist. She studied under a leading member of the Heidelberg School, Frederick McCubbin, at the National Gallery of Victoria Art School from 1902 to 1905 and was an early member of the Melbourne Society of Women Painters and Sculptors. Following the death of her father in 1907, Hilda Rix, her only sibling Elsie and her mother travelled to Europe where she undertook further study in London and then in Paris. Her teachers during the period included John Hassall, Richard Emil Miller and Théophile Steinlen.
After travelling to Tangiers in 1912, Rix held several successful exhibitions of her work, with one drawing, Grande marche, Tanger, purchased by the French government. She was one of the first Australians to paint post-impressionist landscapes, was made a member of the Société des Peintres Orientalistes Français, and had works hung in the Paris Salon first in 1911 and again in 1913. The family evacuated from France to England after the outbreak of World War I. A period of personal tragedy followed, as Rix's sister died in 1914, then her mother in 1915. In 1916 she met and married George Matson Nicholas, only to be widowed the next month when he was killed on the Western Front.
Returning to Australia in 1918, Rix Nicholas once more took up professional painting, and held an exhibition of over a hundred works at Melbourne's Guild Hall. Many sold, including In Picardy, purchased by the National Gallery of Victoria. Following a period painting in rural locations in the early 1920s, Rix Nicholas returned to Europe. A 1925 exhibition in Paris led to the sale of her work In Australia to the Musée du Luxembourg, followed by an extensive tour of her paintings around regional British art galleries. There followed representation in other exhibitions, including at the International Society of Sculptors, Painters and Gravers, and the Royal Academy of Arts, both in London. Following the inclusion of several works in the 1926 Société Nationale des Beaux-Arts Spring exhibition in Paris she was made an Associate of that organisation.

SOLUTION: Who was killed on the Western Front?

PROBLEM: Passage: In early 2005, Frusciante entered the studio to work on his fifth and final studio album with the Chili Peppers, Stadium Arcadium. His guitar playing is dominant throughout the album, and he provides backing vocals on most of the tracks. Although usually following a "less is more" style of guitar playing, he began using a full twenty-four track mixer for maximum effect. In the arrangements, he incorporates a wide array of sounds and playing styles, similar to the funk-influenced Blood Sugar Sex Magik or the more melodic By the Way. He also changed his approach to his playing, opting to contribute solos and allow songs to be formed from jam sessions. In an interview from Guitar World, Frusciante explained how he approached his guitar solos for their album Stadium Arcadium completely differently from those for their previous albums. On Blood Sugar Sex Magik and Californication, Frusciante had a general idea how he wanted his guitar solos to sound. For Stadium Arcadium, almost every guitar solo was completely improvised by Frusciante on the spot. Several reviews have stressed that the influence of Hendrix is evident in his solos on the album, with Frusciante himself backing this up. He also expanded the use of guitar effects throughout the album, and used various other instruments such as the synthesizer and mellotron. He worked continuously with Rubin over-dubbing guitar progressions, changing harmonies and using all his technical resources.Frusciante began a series of collaborations with friend Omar Rodríguez-López and his band The Mars Volta, by contributing guitar and electronic instrumentation to song "Cicatriz ESP" off their album De-Loused in the Comatorium. He also contributed guitar solos on their 2005 album Frances the Mute. In 2006, he helped The Mars Volta complete their third album Amputechture by playing guitar on seven of its eight tracks. In return, Rodriguez-Lopez has played on several of Frusciante's solo albums, as well as making a guest appearance on Stadium Arcadium.

SOLUTION: What is the name of the group that Frusciante provides backing vocals for?

PROBLEM: Passage: A suicide bomber detonates himself at a party in Java, Indonesia, and a Javanese Sultan's daughter, Sultana, is believed to be one of the unidentified victims. Jake Travers, an American posing as a graduate student from Cornell University, was at the scene of the blast and is held as a witness by a police detective of Detachment 88, Lieutenant Hashim. 
After interviewing Jake at the crime scene, Hasim and Jake are attacked by terrorists led by Malik and his henchman Achmed. Jake saves Hashim and kills two terrorists, but Achmed manages to escape. Hashim becomes suspicious after he observes Jake's combat skills. Jake and Hashim are brought to the hospital where Hashim's wife meets Jake. At Hashim's wife's insistence, Hashim invites Jake to their house for breakfast. At the house, Hashim tells Jake that he ran a background check on him through Interpol. Jake tells Hashim he is an FBI agent conducting an undercover investigation, and suggests they cooperate with one another. 
Returning to his apartment, Jake faxes to a friend stateside a photo of a tattoo from the corpse believed to be Sultana's. Jake's friend informs him that the tattoo is typically used by Chinese high-class prostitutes, which confirms Jake's suspicion that the body is not Sultana's.
Jake follows a lead to a night club, where he brings home a prostitute bearing a similar tattoo. When the prostitute cooperates with Jake, they are ambushed by Hashim's terrorists and a Chinese gang operating the prostitution ring. The police, who had been covertly surveilling Jake, intervene and suffer casualties in the fight. Jake flees the scene, but the police eventually capture him.

SOLUTION:
Who begins to suspect an American posing as a graduate student after observing his combat skills?
