Background: Sandman (Wesley Dodds) is a fictional character, a superhero who appears in American comic books published by DC Comics. The first of several DC characters to bear the name Sandman, he was created by writer Gardner Fox and artist Bert Christman. Attired in a green business suit, fedora, and gas mask, the Sandman used a gun emitting a sleeping gas to sedate criminals. He was originally one of the mystery men to appear in comic books and other types of adventure fiction in the 1930s but later was outfitted with a unitard/cowl costume and developed into a proper superhero, acquiring sidekick Sandy, and founding the Justice Society of America.
Context: Dodds is one of a number of Justice Society members who finds themselves in the "Ragnarok Dimension" during the early Modern Age of comic books. The Last Days of the Justice Society of America Special (1986) wrote the post-Crisis tale of a time-warped wave of destruction ready to engulf the world. Dodds and his JSA teammates enter into a limbo to engage in an eternal battle that would allow the universe to continue its existence. This was later revealed to be a simulation created by Odin, which he intended to give to Dream as a bribe. Dodds, Dream's protege, and Hawkman, the grandfather of Dream's appointed successor are the only JSA members we see at this time. This lasted only until 1992 when DC published Armageddon: Inferno. This mini-series ended with the JSA members leaving limbo and entering the 'real' world. Justice Society of America (1992-1993) showed how the JSA members handled returning to normal life. For the Sandman, the series depicted him as an old, thin man with a balding scalp and a sharp wit. Starting with issue #1 his physical condition became important as writer Len Strazewski had him suffer a stroke at the first sign of a villainous attack. Both his age and his physical limitations became a theme writers would use in this character's post-Crisis stories. During Zero Hour, Dodds is returned to his proper age by the Extant. Later, Wesley Dodds is shown as retired and living with Dian Belmont though occasionally coming out of it, most notably in a team-up with Jack Knight, the son of Dodds' JSA teammate Starman. When Dian is diagnosed with a terminal disease, the two travel the world together until her death. Towards the end of his life, Dodds' prophetic dreams alert him to the identity and location of the new Doctor Fate, prompting him to contact the Gray Man, a being created from the residue of others' dreams, as well as his old friend Speed Saunders to instruct them to warn his former teammates about what he has discovered. Waiting on a clifftop, he is subsequently confronted by the powerful villain Mordru, who intends to force Dodds to tell him the identity of the new Doctor Fate, only for Dodds to distract Mordru with his gas-gun long enough to commit suicide by jumping off the cliff rather than allow Mordru to torture him into submission. His last thoughts were that his final slumber would be free of nightmares as he is reunited with Dian. His youthful but now grown-up sidekick, Sandy the Golden Boy, becomes known simply as Sand and takes his mentor's place as a member of the Justice Society of America as well as his prophetic dreams. Eventually, he takes the name of Sandman.
Question: Who was his mentor?
Answer: Mordru

Problem: Background: The Replacements were an American rock band formed in Minneapolis, Minnesota in 1979. Initially a punk rock band, they are considered pioneers of alternative rock. The band was composed of the guitarist and vocalist Paul Westerberg, guitarist Bob Stinson, bass guitarist Tommy Stinson and drummer Chris Mars for most of its career. Following several acclaimed albums, including Let It Be and Tim, Bob Stinson left the band in 1986, and Slim Dunlap joined as lead guitarist.
Context: When the band's first album, Sorry Ma, Forgot to Take Out the Trash, was released in August 1981, it received positive reviews in local fanzines. Option's Blake Gumprecht wrote, "Westerberg has the ability to make you feel like you're right in the car with him, alongside him at the door, drinking from the same bottle." The album contained the band's first single, "I'm in Trouble", Westerberg's "first truly good song". Sorry Ma included the song, "Somethin to Du", a homage to another Minneapolis punk band, Husker Du. The Replacements had a friendly rivalry with the band, which started when Twin/Tone chose the Replacements over Husker Du, and Husker Du landed an opening slot at a Johnny Thunders gig that the Replacements had wanted. Husker Du also influenced the band's music. The Replacements began playing faster and became more influenced by hardcore punk. Despite this, the band did not feel part of the hardcore scene. As Mars later stated, "We were confused about what we were." Sometime in late 1981, the Replacements played a song called "Kids Don't Follow". Jesperson was convinced the song sounded like a hit and pleaded with the Twin/Tone co-owners Stark and Hallman, "I will do anything to get this out. I will hand-stamp jackets if I have to." The partners agreed to fund the recording, but Jesperson and virtually everyone he knew had to hand-stamp ten thousand white record jackets. The band recorded eight tracks within a week, with Jesperson as producer. Their "balls-to-the-wall hardcore punk attempt", their first EP Stink, containing "Kids Don't Follow" and seven other songs, was released in June 1982, six months after the Chicago show. The Replacements began to distance themselves from the hardcore punk scene after the release of Stink. "We write songs rather than riffs with statements," Westerberg later stated. Inspired by other rock subgenres, he had been writing songs that incorporated a wide range of musical styles. He even wrote an acoustic ballad, "You're Getting Married One Night", but when he played it to the rest of the band, it was met with silence. "Save that for your solo album, Paul," Bob Stinson said. "That ain't the Replacements". The track remained unreleased for years. Westerberg realized his toughest audience was the band itself, later saying, "If it doesn't rock enough, Bob will scoff at it, and if it isn't catchy enough, Chris won't like it, and if it isn't modern enough, Tommy won't like it."
