Some context: Leonardo, nicknamed Leo, is a fictional character and one of the four main characters in Teenage Mutant Ninja Turtles comics and all related media. He is often depicted wearing a blue eye mask. His signature weapons are two katanas. Leonardo is the most serious, the most spiritual, the most disciplined, and the most in-line with Splinter's teachings and thoughts, and is the leader of the Turtles.
Leonardo again leads the team in Nickelodeon's 3D computer-animated series. He was voiced by actor Jason Biggs up until "The Wrath of Tiger Claw", Dominic Catrambone for the remainder of the second season and Seth Green beginning in the third season. In this latest version, Leonardo seems to be more experienced and still perfecting his fighting skills and leadership abilities to make more solid decisions and gain more trust from his three younger brothers. He regularly watches an animated science fiction show called Space Heroes (a parody of Star Trek: The Animated Series) and uses it as a guide for his leadership skills, often attempting to quote from the show in an attempt to sound intimidating and heroic, even if most of his attempts fall flat due to him sounding overly cliche.  Leonardo immediately developed romantic feelings for Karai since their first encounter, even though she is his adoptive sister by Splinter; she was taken in by the Shredder after her mother's death and was tasked with destroying her birth family (including Leo) before changing sides upon discovering her true heritage as his adopted sister. His weapons here are purely dual katanas, which he uses in the Niten Ryu style of kenjutsu, making him an excellent swordsman. Despite the fact the other three turtles have added traits in this series, Leonardo is almost completely normal but now has blue eyes. Upon the sudden demise of his adopted father and master, he reluctantly steps up as sensei in addition to being leader, which puts even more pressure on him. He is visited, on occasion, by the spirit of Splinter who encourages him to lead his family and friends to stopping new evils.  In addition to his natural ninjitsu skills, he eventually developed the strong innate ability to heal via an enchanted mantra known as "the healing hands." By chanting the incantation and making the right hand seals, Leo is fully capable of revitalizing his inner strength and counteract even the most lethal of poisons and venom of "the healing hands." He managed to develop and utilize it to counteract the lethal venom of Karai, and attempted to use it on her to release her from the Shredder's control but failed. He then succeeded in saving Casey and Michelangelo from death. According to Splinter, he shows great gifts as a healer, and that being at the edge of his life had given him "a power that few martial artists can tap."
Did he defeat karai?
A: attempted to use it on her to release her from the Shredder's control but failed.

Some context: Hoagland Howard "Hoagy" Carmichael (November 22, 1899 - December 27, 1981) was an American composer, pianist, singer, actor, and bandleader. American composer and author Alec Wilder described Carmichael as the "most talented, inventive, sophisticated and jazz-oriented of all the great craftsmen" of pop songs in the first half of the twentieth century. Carmichael was one of the most successful Tin Pan Alley songwriters of the 1930s, and was among the first singer-songwriters in the age of mass media to utilize new communication technologies, such as television and the use of electronic microphones and sound recordings. Carmichael composed several hundred songs, including fifty that achieved hit record status.
Carmichael and lyricist Johnny Mercer received an Academy Award for Best Music, Song, for "In the Cool, Cool, Cool of the Evening," which was featured in the 1951 film Here Comes the Groom. "Ole Buttermilk Sky" received an Oscar nomination for Best Music, Song, of 1946, but it was not the winner. Carmichael's recording of "Star Dust" in 1927 at the Gennett Records studio that includes him playing the piano solo was inducted into the Grammy Hall of Fame. In addition, it was selected for inclusion in the National Recording Registry at the Library of Congress in 2004.  Carmichael was inducted into the Hollywood Walk of Fame on February 8, 1960. (His sidewalk star tribute is located at 1720 Vine Street in Hollywood.) In 1971 Carmichael was inducted into the Songwriters Hall of Fame as one of its initial ten inductees. In 2007 Carmichael was inducted into the Gennett Records Walk of Fame in Richmond, Indiana. Bronze and ceramic medallions, one for each of the inductees, have been placed near the location of the Starr Piano Company's manufacturing complex, the site of the Gennett Records studio where he first recorded "Star Dust" in 1927. On July 5, 2008, a mural with his portrait was dedicated to him on the south wall of the Readmore building in Richmond, Indiana.  Carmichael is memorialized with an Indiana state historical marker, installed in 2007 in front of the former Book Nook (one of Carmichael's favorite local hangouts) on South Indiana Avenue, near the corner of Kirkwood and Indiana Streets in Bloomington. The marker is located across the street from the heart of the Indiana University campus. In 2008 the bronze Hoagy Carmichael Landmark Sculpture by artist Michael McAuley was installed at the northeast corner of the IU Auditorium on IU's Bloomington campus.  On June 27, 1979, the Newport Jazz Festival honored Carmichael with a tribute concert, "The Star Dust Road: A Hoagy Carmichael Jubilee", at New York City's Carnegie Hall.  "Georgia On My Mind", composed by Carmichael with lyrics by Stuart Gorrell, is the U.S. state of Georgia's official song.
