Problem: Background: The Riddler (Edward Nigma) is a fictional supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. The character made his first appearance in Detective Comics #140 (October, 1948) and was created by Bill Finger and Dick Sprang. Depicted as a Gotham City criminal mastermind, the Riddler takes delight in incorporating riddles and puzzles into his plots, and leaves them as clues for the authorities and Batman to solve. The character is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery.
Context: The Riddler makes his first true appearance in the new DC continuity relaunch, DC Rebirth, in Batman #19. An inmate of Arkham once again, he rather cooperatively assists Bane in unlocking a high tech door, allowing Bane access to confront Batman. In the eight-part story-arc "War of Jokes and Riddles", commencing with Batman Vol. 3 #25, flashbacks to a year after the events of "Zero Year" have Batman recounting the details of a war between Riddler and Joker. He is first seen in custody at the GCPD, assisting them in solving a variety of crimes, including locating Joker's whereabouts, before stabbing a police officer to death 26 times. Blackmailing the approaching guards with details of their children and families, Riddler walks out freely before intruding into Joker's office. Riddler seemingly offers the Joker a partnership, acknowledging that if either of the two men individually kill Batman, the other will be left forever unsatisfied. However the Joker shoots Riddler in the stomach and quickly departs, Batman appearing through the window and giving chase. Left in a pool of his own blood, Riddler rose to his feet and limped out of the office, seemingly unfazed. Edward quickly healed from the wound, carving a question marked shaped scar over the wound, before murdering Dr. Jaime Knowles. Riddler is then seen meeting with Poison Ivy, discussing the Joker's need to rid anyone who could potentially kill Batman before him. The duo are then ambushed by gunmen working for Carmine Falcone under the orders of the Joker to kill Riddler within the hour. However Poison Ivy attacks the gunmen with her vines, allowing Edward and herself to leave. Riddler eventually formed his team, consisting on himself, Poison Ivy, Scarecrow, Deathstroke, Clayface, Killer Croc, Two-Face, Firefly, and Victor Zsasz. Waging war on Joker's team across Gotham, Riddler is responsible for poisoning Charles Brown's son, resulting in his transformation into Kite Man who joins up with Joker's team consisting of Cluemaster, Deadshot, Mad Hatter, Man-Bat, Mr. Freeze, Penguin, Solomon Grundy, and Ventriloquist. The war continues, with Riddler and Joker claiming territories across Gotham, before Riddler, who'd convinced Batman to side with him during the conflict, blackmails and interrogates Kite Man into giving up Joker's location. However Batman, after a brief fight between him, Riddler and Joker, becomes disgusted by Riddler's actions and quickly grabs a blade, breaking his one rule of No Killing in order to stab Riddler. However Joker, who finally begins to laugh again, prevents Batman from doing so. The present day Riddler shows up next in 'Deathstroke #25' as a member of The Society who have placed Deathstroke on trial for appearing to have reformed. Riddler, using Hector Hammond's abilities, convinces the Society that Deathstroke is indeed evil by showcasing a simulation of Deathstroke killing them all right before Deathstroke himself is kidnapped.
Question: What happened after that?
Answer: healed from the wound, carving a question marked shaped scar over the wound, before murdering Dr. Jaime Knowles.

Problem: Background: Toru Takemitsu (Wu Man Che , Takemitsu Toru, October 8, 1930 - February 20, 1996) pronounced [takemitsW to:rW] was a Japanese composer and writer on aesthetics and music theory. Largely self-taught, Takemitsu possessed consummate skill in the subtle manipulation of instrumental and orchestral timbre. He is famed for combining elements of oriental and occidental philosophy to create a sound uniquely his own, and for fusing opposites together such as sound with silence and tradition with innovation. He composed several hundred independent works of music, scored more than ninety films and published twenty books.
Context: In 1948, Takemitsu conceived the idea of electronic music technology, or in his own words, to "bring noise into tempered musical tones inside a busy small tube." During the 1950s, Takemitsu had learned that in 1948 "a French [engineer] Pierre Schaeffer invented the method(s) of musique concrete based on the same idea as mine. I was pleased with this coincidence." In 1951, Takemitsu was a founding member of the anti-academic Jikken Kobo (Shi Yan Gong Fang , "experimental workshop"): an artistic group established for multidisciplinary collaboration on mixed-media projects, who sought to avoid Japanese artistic tradition. The performances and works undertaken by the group introduced several contemporary Western composers to Japanese audiences. During this period he wrote Saegirarenai Kyusoku I ("Uninterrupted Rest I", 1952: a piano work, without a regular rhythmic pulse or barlines); and by 1955 Takemitsu had begun to use electronic tape-recording techniques in such works as Relief Statique (1955) and Vocalism A*I (1956). Takemitsu also studied in the early 1950s with the composer Fumio Hayasaka, perhaps best known for the scores he wrote for films by Kenji Mizoguchi and Akira Kurosawa, the latter of whom Takemitsu would collaborate with decades later. In the late 1950s chance brought Takemitsu international attention: his Requiem for string orchestra (1957 listen ), written as an homage to Hayasaka, was heard by Igor Stravinsky in 1958 during his visit to Japan. (The NHK had organised opportunities for Stravinsky to listen to some of the latest Japanese music; when Takemitsu's work was put on by mistake, Stravinsky insisted on hearing it to the end.) At a press conference later, Stravinsky expressed his admiration for the work, praising its "sincerity" and "passionate" writing. Stravinsky subsequently invited Takemitsu to lunch; and for Takemitsu this was an "unforgettable" experience. After Stravinsky returned to the U.S., Takemitsu soon received a commission for a new work from the Koussevitsky Foundation which, he assumed, had come as a suggestion from Stravinsky to Aaron Copland. For this he composed Dorian Horizon, (1966), which was premiered by the San Francisco Symphony Orchestra, conducted by Copland.
