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: In February 1997, Wallace traveled to California to promote Life After Death and record a music video for its lead single, "Hypnotize". On March 5, 1997, he gave a radio interview with The Dog House on KYLD in San Francisco. In the interview, he stated that he had hired a security detail, since he feared for his safety; this was because he was a celebrity figure in general, not because he was a rapper.On March 8, 1997, Wallace presented an award to Toni Braxton at the 11th Annual Soul Train Music Awards in Los Angeles and was booed by some of the audience. After the ceremony, he attended an afterparty hosted by Vibe and Qwest Records at the Petersen Automotive Museum in Los Angeles. Guests included Evans, Aaliyah, Combs, and members of the Crips and Bloods gangs.On March 9, 1997, at 12:30 a.m. (PST), after the fire department closed the party early due to overcrowding, Wallace left with his entourage in two GMC Suburbans to return to his hotel. He traveled in the front passenger seat alongside his associates, Damion "D-Roc" Butler, Lil' Cease and driver Gregory "G-Money" Young. Combs traveled in the other vehicle with three bodyguards. The two trucks were trailed by a Chevrolet Blazer carrying Bad Boy's director of security, Paul Offord.By 12:45 a.m. (PST), the streets were crowded with people leaving the party. Wallace's truck stopped at a red light 50 yards (46 m) from the museum. A black Chevy Impala pulled up alongside Wallace's truck. The driver of the Impala, an African-American male dressed in a blue suit and bow tie, rolled down his window, drew a 9 mm blue-steel pistol and fired at the GMC Suburban. Four bullets hit Wallace. His entourage rushed him to Cedars-Sinai Medical Center, but he was pronounced dead at 1:15 a.m. (PST).Wallace's funeral was held on March 18, 1997, at the Frank E. Campbell Funeral Chapel in Manhattan. There were among 350 mourners at the funeral, including Queen Latifah, Flava Flav, Mary J. Blige, Lil' Kim, Lil' Cease, Run–D.M.C., DJ Kool Herc, Treach from Naughty by Nature, Busta Rhymes, Salt-N-Pepa, DJ Spinderella, Foxy Brown, Sister Souljah and others. After the funeral, his body was cremated and the ashes were given to his family.

SOLUTION: What is the last name of the person who was booed by some of the audience at the 11th Annual Soul Train Music Awards in Los Angeles?

PROBLEM: Passage: Ride the Lightning is the second studio album by American heavy metal band Metallica, released on July 27, 1984, by the independent record label Megaforce Records. The album was recorded in three weeks with producer Flemming Rasmussen at the Sweet Silence Studios in Copenhagen, Denmark. The artwork, based on a concept by the band, depicts an electric chair being struck by lightning flowing from the band logo. The title was taken from a passage in Stephen King's novel The Stand. Although rooted in the thrash metal genre, the album showcased the band's musical growth and lyrical sophistication. This was partly because bassist Cliff Burton introduced the basics of music theory to the rest of the band and had more input in the songwriting. Instead of relying strictly on fast tempos as on its debut Kill 'Em All, Metallica broadened its approach by employing acoustic guitars, extended instrumentals, and more complex harmonies. The overall recording costs were paid by Metallica's European label Music for Nations because Megaforce was unable to cover it. It was the last album to feature songwriting contributions from former lead guitarist Dave Mustaine, and the first to feature contributions from his replacement, Kirk Hammett.
Ride the Lightning received positive response from music critics, who saw it as a more ambitious effort than its predecessor. Metallica promoted the album on the Bang That Head That Doesn't Bang European tour in late 1984, and on its North American leg in the first half of 1985. The band performed at major music festivals such as Monsters of Rock and Day on the Green later that year. Two months after its release, Elektra Records signed Metallica to a multi-year deal and reissued the album. Ride the Lightning peaked at number 100 on the Billboard 200 with no radio exposure. Although 75,000 copies were initially pressed for the American market, the album sold half a million by November 1987. It was certified 6× platinum by the Recording Industry Association of America (RIAA) in 2012 for shipping six million copies in the United States. Many rock publications have ranked Ride the Lightning on their best album lists, saying it had a lasting impact on the genre.

SOLUTION: Who was unable to cover the recording costs?

PROBLEM: Passage: There are more than 20 major dams on the Willamette's tributaries, as well as a complex series of levees, dikes, and channels to control the river's flow.
The only dam on the Willamette's main stem is the Willamette Falls Dam, a low weir-type structure at Willamette Falls that diverts water into the headraces of the adjacent mills and a power plant.  The locks at Willamette Falls were completed in 1873.  Elsewhere on the main stem, numerous minor flow-regulation structures force the river into a narrower and deeper channel to facilitate navigation and flood control.The dams on the Willamette's major tributaries are primarily large flood-control, water storage, and power-generating dams. Thirteen of these dams were built from the 1940s through the 1960s to be operated by the United States Army Corps of Engineers (USACE), and 11 of those produce hydropower. Flood-control dams operated by the USACE are estimated to hold up to 27 percent of the Willamette's runoff. They are used to regulate river flows so as to cut peaks off floods and increase low flows in late summer and autumn, and to divert water into deeper, narrower channels to prevent flooding. In addition, a relatively small of amount of the water stored in the reservoirs is used for irrigation.
Detroit Dam on the North Santiam River is the second tallest dam in the Willamette River basin after Cougar Dam. It is 463 feet (141 m) high and stores 455,000 acre feet (561,000,000 m3) of water. Lookout Point Dam on the Middle Fork Willamette River, forming Lookout Point Lake, has the largest water storage capacity, at 477,700 acre feet (589,200,000 m3). The other 11 dams are Big Cliff on the North Santiam River; Green Peter and Foster on the Santiam River; Cougar on the South Fork McKenzie River;  Blue River on the Blue River; Fern Ridge on the Long Tom River; Hills Creek, Dexter on the Middle Fork Willamette River; Fall Creek on Fall Creek; Cottage Grove on the Coast Fork Willamette River, and Dorena on the Row River.A continuing controversy about these high dams involves Chinook salmon and steelhead blocked from roughly half of their historic habitat and spawning grounds on the Willamette's major tributaries. Unable to survive and reproduce as they once did, they have been "brought to the brink of extinction".  Endangered species listings and a subsequent lawsuit by Willamette Riverkeeper led to a plan to improve fish passage and other actions to help native fish recover in 2008. Since then, work has proceeded slowly, and the Corps, citing engineering difficulties and cost, may not meet the original agreed-upon deadline of 2023 for a system of effective remedies.Other major dams in the Willamette watershed are owned by other interests; for example, several hydroelectric facilities on the Clackamas River are owned by Portland General Electric. They include the River Mill Hydroelectric Project, the Oak Grove project, and the dam at Timothy Lake.

SOLUTION:
What structures are used to produce hydropower?
