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.

PROBLEM: Passage: Daphne Blake is a high school student who has a semi-popular web show discussing the possibility of aliens and supernatural occurrences. Velma Dinkley is Daphne's supportive yet critical online friend, who believes there is a logical explanation for everything. After Velma web chats Daphne following her latest episode, she reveals to Velma that her parents will be moving to Ridge Valley, where Velma currently goes to high school.
After having a perfect morning at home, Daphne embarks on her first day at Ridge Valley High. She quickly meets Carol, her senior advisor, who shows her the school's expansive collection of advanced technology from Bloom Innovative, a famous technology company. While on her tour, Daphne runs into Velma, who does not speak to her. Later that afternoon, Daphne sees a student named Spencer walk into an open locker as if he were in a trance.
At home, Daphne's father reveals that he has sheltered Daphne all her life, going to extreme lengths to follow her around everywhere in an attempt to make Daphne's life "perfect". Shocked and frustrated at her father, Daphne vows to do everything on her own without her father's assistance. The next day, Daphne gets into a heated argument with Velma over their science project, which Velma intentionally sabotaged. The argument results in the girls getting sent to the principal's office, who puts them on "the best couch for conflict resolution". The couch helps the girls put aside their differences, and Velma reveals she was protecting Daphne because she knew of the strange happenings at the school. Daphne and Velma vow to solve the mystery of the disappearing students.

SOLUTION: What are the full names of the friends who go to Ridge Valley High?

PROBLEM: Passage: "Missing My Baby" is a mid-tempo R&B ballad with influences of urban and soul music. It is in the key of D major, at 144 beats per minute in common time. The recording incorporates melisma, with sung poetry during the downtempo part of the song. The melody is accompanied by backing vocals, and instrumentation is provided by an electric piano, drums, a keyboard, a synthesizer and strings. Contemporary music critics praised Selena's emotive enunciation, which emphasized the song's title and central theme. R&B duo Full Force were the backing vocalists for the original and remix versions of "Missing My Baby".J.R. Reynolds, formerly of Billboard, called "Missing My Baby" a "dreamy ballad" with an "R&B-styled melody under Selena's pop vocals". Ramiro Burr of the Austin American-Statesman described it as a soul ballad. Jerry Johnston of the Deseret News thought that Selena displayed a "Leslie Gore [sic] baby-voice" in "Missing My Baby" and that she "displays a wonderful suppleness in her voice". The Virginian-Pilot said that the song was built on hooks that recall Diana Ross's "Missing You", which is a tribute to Marvin Gaye, and the Beach Boys' "Good to My Baby".The song begins with a drum solo before the other instruments enter to form the musical foundation. Selena sings to her absent lover about how much she misses him, saying that he is "always on [her] mind" and that she feels lonely when he is not with her. Three times she sings, "I often think of the happy times we spent together / And I just can't wait to tell you that I love you". In the chorus, she sings of wanting to hold him tight and feel his heartbeat.

SOLUTION: About whom is Selena singing of wanting to hold him tight and feel his heartbeat?

PROBLEM: Passage: George Roger Waters (born 6 September 1943) is an English songwriter, singer, bassist, and composer. In 1965, he co-founded the progressive rock band Pink Floyd. Waters initially served solely as the bassist, but following the departure of songwriter Syd Barrett in 1968, he also became their lyricist, co-lead vocalist, and conceptual leader.
Pink Floyd achieved international success with the concept albums The Dark Side of the Moon (1973), Wish You Were Here (1975), Animals (1977), and The Wall (1979). By the early 1980s, they had become one of the most critically acclaimed and commercially successful groups in popular music; by 2013, they had sold more than 250 million albums worldwide. Amid creative differences, Waters left in 1985 and began a legal dispute with the remaining members over the use of the band's name and material. They settled out of court in 1987.
Waters' solo work includes the studio albums The Pros and Cons of Hitch Hiking (1984), Radio K.A.O.S. (1987), Amused to Death (1992), and Is This the Life We Really Want? (2017). In 2005, he released Ça Ira, an opera translated from Étienne and Nadine Roda-Gils' libretto about the French Revolution.
In 1990, Waters staged one of the largest rock concerts in history, The Wall – Live in Berlin, with an attendance of 450,000. As a member of Pink Floyd, he was inducted into the U.S. Rock and Roll Hall of Fame in 1996 and the UK Music Hall of Fame in 2005. Later that year, he reunited with Pink Floyd bandmates Mason, Wright and David Gilmour for the Live 8 global awareness event, the group's first appearance with Waters since 1981. He has toured extensively as a solo act since 1999; he performed The Dark Side of the Moon in its entirety for his world tour of 2006–2008, and in 2010 began the Wall Live tour, the highest-grossing of all time by a solo artist.

SOLUTION:
What is the last name of the person who co-founded Pink Floyd?
