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.

Passage: Hillsboro () is the fifth-largest city in the State of Oregon and is the county seat of Washington County. Lying in the Tualatin Valley on the west side of the Portland metropolitan area, the city hosts many high-technology companies, such as Intel, that comprise what has become known as the Silicon Forest. At the 2010 Census, the city's population was 91,611.For thousands of years before the arrival of European-American settlers, the Atfalati tribe of the Kalapuya lived in the Tualatin Valley near the later site of Hillsboro. The climate, moderated by the Pacific Ocean, helped make the region suitable for fishing, hunting, food gathering, and agriculture. Settlers founded a community here in 1842, later named after David Hill, an Oregon politician. Transportation by riverboat on the Tualatin River was part of Hillsboro's settler economy. A railroad reached the area in the early 1870s and an interurban electric railway about four decades later. These railways, as well as highways, aided the slow growth of the city to about 2,000 people by 1910 and about 5,000 by 1950, before the arrival of high-tech companies in the 1980s.
Hillsboro has a council–manager government consisting of a city manager and a city council headed by a mayor. In addition to high-tech industry, sectors important to Hillsboro's economy are health care, retail sales, and agriculture, including grapes and wineries. The city operates more than twenty parks and the mixed-use Hillsboro Stadium, and ten sites in the city are listed on the National Register of Historic Places (NRHP). Modes of transportation include private vehicles, public buses and light rail, and aircraft using the Hillsboro Airport. The city is home to Pacific University's Health Professions Campus. Notable residents include two Oregon governors.
What is on the east side of Hillsboro?

Passage: Two days after the events of the first film, a traumatized and blood-covered Sarah escapes the cave with no memory of the events. She is taken to a hospital, where it is found that some of the blood on her belongs to Juno Kaplan. Sheriff Vaines takes his deputy Elen Rios, Sarah, and three spelunking specialists – Dan, Greg, and Cath – to the cave to find the missing women. The team members are sent down via an old mine shaft operated by the old, mysterious Ed Oswald.
The group discovers Rebecca's mutilated body, causing Sarah to have flashbacks of the crawlers and causing Vaines to believe Sarah may be responsible for the girls' disappearance.  While crawling through a tunnel, she attacks Vaines and the others, causing the others to split up. Vaines runs to search for Sarah, and in the process is surprised by a crawler, and fires his gun in a panic, causing a minor collapse in the cavern which traps Cath, separating her from Rios, Dan, and Greg.  The three decide to find an alternate way around in order to try to free Cath and arrive in a room full of bones, where they find Holly's video camera. They watch it and realize the women were attacked by the crawlers. The three are then themselves attacked by crawlers and separated.
Rios starts calling for help, alerting the crawlers to her location, but is rescued by Sarah.  The two then watch as a crawler kills Dan and drags his body away, prompting Sarah to inform Rios that the crawlers are blind and hunt via sound. After escaping from and killing a crawler, Cath finds Greg before the two escape from another crawler and find Sam's body. They decide to try to use her to swing across a chasm, but are attacked again. Greg sacrifices himself to buy time for Cath, but she ultimately does not survive.
Who attacks someone, causing the group to split up?

Passage: Radiohead finished recording their eighth album, The King of Limbs, in January 2011. Following the protracted recording and more conventional rock instrumentation of In Rainbows, Radiohead developed The King of Limbs by sampling and looping their recordings with turntables. Radiohead announced the album on Valentine's Day and released it as a download on 18 February 2011 through their website. It was followed by a retail release on CD and vinyl formats in March on XL, and a special "newspaper album" edition in May. The King of Limbs sold an estimated 300,000 to 400,000 copies through Radiohead's website; the retail edition debuted at number six on the US Billboard 200 and number seven on the UK Albums Chart. It was nominated for five categories in the 54th Grammy Awards. Two tracks not included on The King of Limbs, "Supercollider" and "The Butcher", were released as a double A-side single for Record Store Day in April. A compilation of King of Limbs remixes by various artists, TKOL RMX 1234567, was released in September.To perform the rhythmically complex King of Limbs material live, Radiohead enlisted a second drummer, Clive Deamer, who had worked with Portishead and Get the Blessing. Deamer has joined Radiohead on subsequent tours. In June, Radiohead played a surprise performance on the Park stage at the 2011 Glastonbury Festival, performing songs from The King of Limbs for the first time. With Deamer, Radiohead recorded The King of Limbs: Live from the Basement, released online in August 2011. It was also broadcast by international BBC channels and released on DVD and Blu-ray in January 2012. The performance included two new songs, "The Daily Mail" and "Staircase", released as a double A-side download single in December 2011. In February 2012, they began their first extended North American tour in four years, including dates in the United States, Canada and Mexico. On tour, they recorded material at Jack White's studio Third Man Records, but discarded the recordings.On 16 June 2012, an hour before gates were due to open at Toronto's Downsview Park for the final concert of Radiohead's North American tour, the roof of the venue's temporary stage collapsed, killing drum technician Scott Johnson and injuring three other members of Radiohead's road crew. After rescheduling the tour, Radiohead paid tribute to Johnson at their next concert, in Nîmes, France, in July. In June 2013, Live Nation Canada Inc, two other organisations and an engineer were charged with 13 charges under Ontario health and safety laws. In September 2017, after several delays, the case was dropped under the Jordan ruling, which sets strict timelines on trials. Radiohead released a statement condemning the decision. A 2019 inquest returned a verdict of accidental death.
What was the name of the album released as a download on 18 February 2011?
