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: The Willamette River ( (listen) wil-AM-it) is a major tributary of the Columbia River, accounting for 12 to 15 percent of the Columbia's flow. The Willamette's main stem is 187 miles (301 km) long, lying entirely in northwestern Oregon in the United States. Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia.
Originally created by plate tectonics about 35 million years ago and subsequently altered by volcanism and erosion, the river's drainage basin was significantly modified by the Missoula Floods at the end of the most recent ice age. Humans began living in the watershed over 10,000 years ago. There were once many tribal villages along the lower river and in the area around its mouth on the Columbia. Indigenous peoples lived throughout the upper reaches of the basin as well.
Rich with sediments deposited by flooding and fed by prolific rainfall on the western side of the Cascades, the Willamette Valley is one of the most fertile agricultural regions in North America, and was thus the destination of many 19th-century pioneers traveling west along the Oregon Trail. The river was an important transportation route in the 19th century, although Willamette Falls, just upstream from Portland, was a major barrier to boat traffic. In the 21st century, major highways follow the river, and roads cross it on more than 50 bridges.
Since 1900, more than 15 large dams and many smaller ones have been built in the Willamette's drainage basin, 13 of which are operated by the U.S. Army Corps of Engineers (USACE). The dams are used primarily to produce hydroelectricity, to maintain reservoirs for recreation, and to prevent flooding. The river and its tributaries support 60 fish species, including many species of salmon and trout; this is despite the dams, other alterations, and pollution (especially on the river's lower reaches). Part of the Willamette Floodplain was established as a National Natural Landmark in 1987 and the river was named as one of 14 American Heritage Rivers in 1998.

Answer: What organization operates 13 of the dams built in the river that is a major tributary of the Columbia river?


Question: Passage: When Ella Finch and her sister Kate inherit $30,000 each just after the end of World War I, Ella becomes dissatisfied with her dull life in South Bend, Indiana, and with Kate's butcher boyfriend Willis. She is convinced she can rectify both problems by taking Kate to New York City. Her wisecracking cigar salesman husband Ernie is unable to change her mind, so he reluctantly goes along, postponing a promotion at work by claiming to his boss, A. J. Gluskoter, that his wife is sick and needs a stay at a sanitarium. On the train, they meet New Yorker Francis Griffin. Ernie is less impressed with him than his wife and sister-in-law.
In New York, Ella helps Katie try to win over Francis, but it turns out that he is actually infatuated with Ella. She has to punch him to fend off his unexpected advances. Ernie shows up later and knocks him down too.
Ella then rents an apartment. Ella meets their wealthy neighbor, Lucius Trumball, who invites them all over for drinks. Ella is delighted, but Kate is not pleased when she discovers that Trumball is much older than her. Later she finds out he is also married when his wife returns unexpectedly from Timbuktu.
They return to the hotel they stayed at before, where they meet Herbert Daley, who owns race horses. At the track, Daley persuades them to bet on his horse. It wins, but then Daley's jockey, Sid Mercer, shows interest in Kate, much to Daley's annoyance. Kate secretly sees Sid while also going to the track with Daley with Ella and Ernie. Daley returns early from a trip and catches Sid kissing Kate, but Kate assures him there is nothing serious going on, and they become engaged.

Answer: What is the full name of the wife of the wisecracking cigar salesman?


Question: Passage: After moving to Los Angeles, Keenan met Adam Jones who had in college heard him singing on a demo. Impressed with Keenan's vocals, Jones suggested that they form a band. Reluctant, Keenan eventually agreed and, in 1990, Tool was formed. Fronted by Keenan, the eventual lineup included guitarist Jones; his neighbor, drummer Danny Carey; and bassist Paul D'Amour, who would later be replaced by Justin Chancellor.
Tool signed to Zoo Entertainment in November 1991 and released the Opiate EP the following year. To support this release, the band toured with Fishbone and Rage Against the Machine.
Fifteen years after the band's formation, Tool had acquired what Dan Epstein of Revolver described as a devoted "cult" following, and in May 2006 the band released 10,000 Days, an album in which Keenan sang about more personal issues in contrast to previous attempts to inspire change. His mother, who inspired the song "Jimmy" on Ænima, also served as the inspiration for "Jambi", and the two-part song "Wings for Marie" and "10,000 Days (Wings for Marie, Pt 2)", which deals with her 2003 death after 27 years, or around 10,000 days, of suffering. The album sold 564,000 copies in its opening week in the U.S. and was No. 1 on the Billboard 200 charts. However, 10,000 Days was received less favorably by critics than its predecessor Lateralus had been.Following 10,000 Days, Tool has one album remaining to fulfill the obligation of its record contract. Though there is little information available on plans for this album, the band is steadily working towards its fifth studio release.  Tool has worked around Keenan and his side projects since 1999, starting with the creation of A Perfect Circle, which has led to several years between projects. Regarding the future of Tool, Keenan stated in a 2007 interview with Spin, "We'll make music together until one of us is dead."On March 24, 2009, a summer tour was announced on Tool's website, and in a March 26 press release Tool was confirmed as a headliner for the second annual Mile High Music Festival in Commerce City, Colorado, with Widespread Panic and The Fray. Tool also headlined Lollapalooza 2009 in Chicago, Illinois.On December 12, 2012, Tool's webmaster posted on the band website:.

Answer:
What festival was the band that released 10,000 Days confirmed to headline on March 26?
