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.

Question: Passage: In support of Nine Inch Nails' third full-length studio album, The Fragile, the live-band reformed for the Fragility tour.  The lineup remained largely the same from the Self-Destruct tour, featuring Finck, Clouser, and Lohner.  To replace long-time member Vrenna, Reznor held open auditions to find a new drummer, eventually picking then-unknown Jerome Dillon.  Dillon would remain a member of the live band until 2005.
Nine Inch Nails' record label at the time, Interscope Records, reportedly refused to fund the promotional tour following The Fragile's lukewarm sales.  Reznor instead committed himself to fund the entire tour out of his own pocket, concluding that "The reality is, I’m broke at the end of the tour," but also adding "I will never present a show that isn’t fantastic."The Fragility tour began in late 1999, running until mid-2000, and was broken into two major legs, Fragility 1.0 and Fragility 2.0 respectively.  Destinations included Europe, Japan, New Zealand, Australia, and North America.  Before the first Fragility performance date in Spain, Nine Inch Nails opened their final rehearsal in London to 100 fans. Kick-starting the tour was a performance of the title track from The Fragile at the MTV Video Music Awards.  Atari Teenage Riot opened for Nine Inch Nails during Fragility 1.0, and A Perfect Circle for Fragility 2.0.  At the time, A Perfect Circle featured Josh Freese on drums, who would later replace Dillon and play drums for Nine Inch Nails from 2005 to 2007. The tour featured increasingly large production values, including a triptych video display created by contemporary video artist Bill Viola. Rolling Stone magazine named Fragility the best tour of 2000.In 2002, the tour documentary And All That Could Have Been was released featuring a collection of performances from the Fragility 2.0 tour.  While making the DVD, Reznor commented on the tour in retrospect by saying "I thought the show was really, really good when we were doing it", but later admitted that he "can't watch [the DVD] at all. I was sick for most of that tour and I really don't think it was Nine Inch Nails at its best".

Answer: What was the name of the drummer on the Self-Destruct tour?


Question: Passage: South Boston teenager Jason Tripitikas is a fan of martial arts films and awakens from a dream of a battle between the Monkey King and celestial soldiers in the clouds. He visits a pawn shop in Chinatown to buy wuxia DVDs and discovers a golden staff. On his way home, Tripitikas is harassed by some hooligans, whose leader Lupo attempts to use him to help them rob the shop-owner Hop, who is shot by Lupo. Hop tells Tripitikas to deliver the staff to its rightful owner and Tripitikas flees with the staff. He is cornered on the rooftop before being pulled off the roof by the staff.
When Tripitikas regains consciousness, he finds himself in a village in ancient China that is under attack by armored soldiers. The soldiers see his staff and attempt to seize it. He is saved by the inebriated traveling scholar Lu Yan, a supposed "immortal," who remains alert and agile even when drunk. Lu tells him the story of the rivalry between the Monkey King and the Jade Warlord. The Warlord tricked the King into setting aside his magic staff, Ruyi Jingu Bang, and transformed the immortal into a stone statue, but the King cast his staff far away before the transformation. Lu ends the tale with a prophecy about a "Seeker" who will find the staff and free the King. Just then, they are attacked by the Warlord's men again, but manage to escape with the help of Golden Sparrow, a young woman. She reveals that her family was murdered by the Warlord, against whom she has sworn revenge.

Answer: What is the last name of the person that Lupo tries to get to participate in the robbery?


Question: Passage: Jo Elizabeth Stafford (November 12, 1917 – July 16, 2008) was an American traditional pop music singer and occasional actress, whose career spanned five decades from the late 1930s to the early 1980s. Admired for the purity of her voice, she originally underwent classical training to become an opera singer before following a career in popular music, and by 1955 had achieved more worldwide record sales than any other female artist. Her 1952 song "You Belong to Me" topped the charts in the United States and United Kingdom, the record becoming the first by a female artist to reach number one on the U.K. Singles Chart.
Born in Coalinga, California, Stafford made her first musical appearance at age twelve. While still at high school she joined her two older sisters to form a vocal trio named The Stafford Sisters, who found moderate success on radio and in film. In 1938, while the sisters were part of the cast of Twentieth Century Fox's production of Alexander's Ragtime Band, Stafford met the future members of The Pied Pipers and became the group's lead singer. Bandleader Tommy Dorsey hired them in 1939 to perform back-up vocals for his orchestra.
In addition to her recordings with the Pied Pipers, Stafford featured in solo performances for Dorsey. After leaving the group in 1944, she recorded a series of pop standards for Capitol Records and Columbia Records. Many of her recordings were backed by the orchestra of Paul Weston. She also performed duets with Gordon MacRae and Frankie Laine. Her work with the United Service Organizations (USO) giving concerts for soldiers during World War II earned her the nickname "G.I. Jo". Starting in 1945, Stafford was a regular host of the National Broadcasting Company (NBC) radio series The Chesterfield Supper Club and later appeared in television specials—including two series called The Jo Stafford Show, in 1954 in the U.S. and in 1961 in the U.K.

Answer:
Who did Tommy Dorsey hire to perform back-up vocals?
