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.

Q: 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.

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

Q: Passage: The 19th-century antiquarian Angharad Llwyd, who wrote a history of Anglesey in 1833, recorded the story noted by Gerald of Wales in the late 12th century that the church once possessed a stone "resembling a human thigh" which would return "of its own accord" however far away it was carried. It was sometimes known as the "homing stone". Gerald said that Hugh d'Avranches, 1st Earl of Chester (who died in 1101) had tested this story by throwing the stone into the sea, chained to a large rock, only to discover that the stone had returned by the next morning. As a result, the Norman earl issued an order that no-one was to attempt to move it.  It was popularly believed that if a couple had sexual intercourse near the stone (something that Gerald said happened "frequently"), it would "sweat large drops of water" and the woman would not become pregnant. Henry Rowlands wrote that the stone had been stolen from the wall of the churchyard (into which it had been set) during his time at St Nidan's.When Rowlands was vicar of St Nidan's, a small chest was found buried about 2 feet (60 cm) under the altar, containing some bone pieces.  His view was that it contained the relics of a saint from St Nidan's or another church in the region (St Beuno's Church, Clynnog Fawr or St Dwynwen's Church, Llanddwyn), and that the chest had placed in St Nidan's during the time of Edward VI for safe keeping. The sandstone reliquary is now kept at the new church, where local tradition maintains that it holds the remains of St Nidan. Jones said that it was "unique, as far as Wales is concerned." The 13th-century font, which Jones described as "a singularly beautiful specimen", was moved to the new church in about 1860.

A: What is the full name of the person who died in 1101?

Q: Passage: Jackson's fifth studio album Janet, was released in May 1993. The record opened at number one on the Billboard 200, making Jackson the first female artist in the Nielsen SoundScan era to do so. Certified sixfold platinum by the RIAA, it sold over 14 million copies worldwide.Janet spawned five singles and four promotional singles, receiving various certifications worldwide. The lead single "That's the Way Love Goes" won the Grammy Award for Best R&B Song and topped the Billboard Hot 100 for eight consecutive weeks. "Again" reached number one for two weeks, while "If" and "Any Time, Any Place" peaked in the top four. "Because of Love" and "You Want This" charted within the top ten.The album experimented with a diverse number of genres, including contemporary R&B, deep house, swing jazz, hip hop, rock, and pop, with Billboard describing each as being "delivered with consummate skill and passion." Jackson took a larger role in songwriting and production than she did on her previous albums, explaining she found it necessary "to write all the lyrics and half of the melodies" while also speaking candidly about incorporating her sexuality into the album's content. Rolling Stone wrote "[a]s princess of America's black royal family, everything Janet Jackson does is important. Whether proclaiming herself in charge of her life, as she did on Control (1986), or commander in chief of a rhythm army dancing to fight society's problems (Rhythm Nation 1814, from 1989), she's influential. And when she announces her sexual maturity, as she does on her new album, Janet., it's a cultural moment."In July 1993, Jackson made her film debut in Poetic Justice. While the film received mixed reviews, her performance was described as "beguiling" and "believably eccentric." Jackson's ballad "Again", which was written for the film, received Golden Globe and Academy Award nominations for "Best Original Song."In September 1993, Jackson appeared topless on the cover of Rolling Stone, with her breasts covered by her then-husband, René Elizondo, Jr. The photograph is the original version of the cropped image used on the Janet album cover, shot by Patrick Demarchelier. The Vancouver Sun reported, "Jackson, 27, remains clearly established as both role model and sex symbol; the Rolling Stone photo of Jackson ... became one of the most recognizable, and most lampooned, magazine covers."The Janet World Tour launched in support of the studio album garnered criticism for Jackson's lack of vocal proficiency and spontaneity, but earned critical acclaim for her showmanship. It was described as erasing the line between "stadium-size pop music concerts and full-scale theatrical extravaganzas.".
