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: All rock now exposed in the area of the park is volcanic, but this has not always been the case. For hundreds of millions of years, the Lassen region underwent repeated uplifting to form mountains, only to have them worn down and submerged under encroaching seas. During the periods of submersion, sand, mud and limestone were deposited. Occasionally volcanic activity was associated with the mountain building.
About 70 million years ago, the area where the Cascade Range is now situated was under the most recent encroachment by the Pacific Ocean. The rocks that make up the modern Sierra Nevada and the Klamath Mountains were already in existence but deeply buried. Some 70 million years before (140 million years before present), the rocks that now make up the Klamaths broke away from the rocks that now make up the Sierras and moved 60 mi (97 km) west, leaving the flooded 'Lassen Strait.' This broad depression was a seaway that connected the marine basin in California with that in east central Oregon.The entire western portion of North America was being deformed from the Laramide orogeny starting around 70 million years ago. Gradually during millions of years, crustal rocks were folded and fractured and the seas driven away. This same bending and breaking of rocks relieved pressure on the hot material beneath the Earth's crust and permitted magma to rise toward the surface. Volcanoes burst into activity starting 30 million years ago from Washington southward along the Cascades and in the area now occupied by the Sierra Nevada. This activity continued until approximately 11 or 12 million years ago. Lava and ash reached a thickness of up to 10,000 ft (3,000 m) in some areas, forming what is now known as the western Cascades. These have been eroded until they are now rolling hills.
Meanwhile, toward the end of this activity, eruptions of a different kind took place on an unprecedented scale in eastern Oregon and Washington. From innumerable cracks, floods of highly fluid basaltic lava spread to cover an area of over 200,000 sq mi (520,000 km2). Now known as the Columbia Plateau, this great lava bed of flood basalt covers much of Oregon, Washington and even parts of Idaho. Northern California's Modoc Plateau is a thinner basaltic flow which some geologists associate with the Columbia Plateau, but there are technical objections to this. The High Cascades took shape as a distinct mountain belt as a result of this upheaval and the bending of the thick blanket of volcanic rocks. During the next 10 million years, a series of new basaltic volcanic cones similar to the shield volcanoes now found in Hawaii were built.

Ex Output:
What is the modern name for the area that formed after floods of highly fluid basaltic lava spread to cover an area of over 200,000 sq mi?

Passage: The frustration at #1 Record's obstructed sales contributed to tension within the band. There was physical fighting between members: Bell, after being punched in the face by Hummel, retaliated by smashing Hummel's new bass guitar to pieces against the wall. Hummel took revenge at a later date: Finding Bell's acoustic guitar in the latter's unattended car, he repeatedly punched it with a screwdriver. In November 1972, Bell quit the band. When work continued on songs for a second album, Bell rejoined, but further conflict soon erupted. A master tape of the new songs inexplicably went missing, and Bell, whose heavy drug intake was affecting his judgment, attacked Fry's parked car. In late 1972, struggling with severe depression, Bell quit the band once more, and by the end of the year Big Star disbanded.
After a few months Chilton, Stephens, and Hummel decided to reform Big Star, and the three resumed work on the second album. The title chosen, Radio City, continued the play on the theme of a big star's popularity and success, expressing what biographer Robert Gordon calls the band's "romantic expectation". As Hummel put it,
This was probably pretty lame, but in those days putting any word in front of the noun "city" to sort of emphasize the totality and pervasiveness of it was just a way of talking people had. If someone suggested going to a store but you had gotten a bad deal there you might say, "Oh no, that place is 'rip off city'." Calling an LP Radio City would be kind of wishful thinking. I mean we hoped it would be played on the radio a lot, making it "radio city". Of course it didn't pan out that way... Stephens recalled: "Radio City, for me, was just an amazing record. Being a three-piece really opened things up for me in terms of playing drums. Drums take on a different role in a three-piece band, so it was a lot of fun. [...] Radio City was really more spontaneous, and the performances were pretty close to live performances."Although uncredited, Bell contributed to the writing of some of the album's songs, including "O My Soul" and "Back of a Car". Shortly before the album's release, Hummel left the band: judging that it would not last, and in his final year at college, he elected to concentrate on his studies and live a more normal life. He was replaced by John Lightman for a short tenure prior to the band dissolving.

Ex Output:
Who was replaced by John Lightman?

Passage: John Winston Ono Lennon (9 October 1940 8 December 1980) was an English singer, songwriter and peace activist who co-founded the Beatles, the most commercially successful band in the history of popular music. He and fellow member Paul McCartney formed a much-celebrated songwriting partnership. Along with George Harrison and Ringo Starr, the group achieved worldwide fame during the 1960s. In 1969, Lennon started the Plastic Ono Band with his second wife, Yoko Ono, and he continued to pursue a solo career following the Beatles' break-up in April 1970.
Born John Winston Lennon in Liverpool, he became involved in the skiffle craze as a teenager. In 1957, he formed his first band, the Quarrymen, which evolved into the Beatles in 1960. Further to his Plastic Ono Band singles such as "Give Peace a Chance" and "Instant Karma!", Lennon subsequently produced albums that included John Lennon/Plastic Ono Band and Imagine, and songs such as "Working Class Hero", "Imagine" and "Happy Xmas (War Is Over)". After moving to New York City in 1971, he never returned to England again. In 1975, he disengaged himself from the music business to raise his infant son Sean, but re-emerged with Ono in 1980 with the album Double Fantasy. He was shot and killed in the archway of his Manhattan apartment building three weeks after the album's release.
Lennon revealed a rebellious nature and acerbic wit in his music, writing, drawings, on film and in interviews. He was controversial through his political and peace activism. From 1971 onwards, his criticism of the Vietnam War resulted in a three-year attempt by the Nixon administration to deport him. Some of his songs were adopted as anthems by the anti-war movement and the larger counterculture.
By 2012, Lennon's solo album sales in the United States had exceeded 14 million units. He had 25 number-one singles on the US Billboard Hot 100 chart as a writer, co-writer or performer. In 2002, Lennon was voted eighth in a BBC poll of the 100 Greatest Britons and in 2008, Rolling Stone ranked him the fifth-greatest singer of all time. In 1987, he was posthumously inducted into the Songwriters Hall of Fame. Lennon was twice posthumously inducted into the Rock and Roll Hall of Fame: first in 1988 as a member of the Beatles and again in 1994 as a solo artist.

Ex Output:
What is the first name of the person who started the Plastic Ono Band with his second wife?
