[EX Q]: Passage: Wood was born in Oxford Street, London, the only child of Henry Joseph Wood and his wife Martha, née Morris. Wood senior had started in his family's pawnbroking business, but by the time of his son's birth he was trading as a jeweller, optician and engineering modeller, much sought-after for his model engines. It was a musical household: Wood senior was an amateur cellist and sang as principal tenor in the choir of St Sepulchre-without-Newgate, known as "the musicians' church".   His wife played the piano and sang songs from her native Wales. They encouraged their son's interest in music, buying him a Broadwood piano, on which his mother gave him lessons. The young Wood also learned to play the violin and viola.
Wood received little religious inspiration at St Sepulchre, but was deeply stirred by the playing of the resident organist, George Cooper, who allowed him into the organ loft and gave him his first lessons on the instrument. Cooper died when Wood was seven, and the boy took further lessons from Cooper's successor, Edwin M. Lott, for whom Wood had much less regard. At the age of ten, through the influence of one of his uncles, Wood made his first paid appearance as an organist at St Mary Aldermanbury, being paid half a crown.  In June 1883, visiting the Fisheries Exhibition at South Kensington with his father, Wood was invited to play the organ in one of the galleries, making a good enough impression to be engaged to give recitals at the exhibition building over the next three months. At this time in his life, painting was nearly as strong an interest as music, and he studied in his spare time at the Slade School of Fine Art. He remained a life-long amateur painter.After taking private lessons from the musicologist Ebenezer Prout, Wood entered the Royal Academy of Music at the age of seventeen, studying harmony and composition with Prout, organ with Charles Steggall, and piano with Walter Macfarren. It is not clear whether he was a member of Manuel Garcia's singing class, but it is certain that he became its accompanist and was greatly influenced by Garcia. Wood also accompanied the opera class, taught by Garcia's son Gustave. Wood's ambition at the time was to become a teacher of singing, and he gave singing lessons throughout his life. He attended the classes of as many singing teachers as he could, although by his own account, "I possess a terrible voice. Garcia said it would go through a brick wall. In fact, a real conductor's voice.". 
Question: What is the last name of the person whose mother gave him piano lessons?
[EX A]: Wood.

Question: What is the last name of the person who Tony rescues?

[EX Q]: Passage: Metallica was formed in Los Angeles, California, in late 1981 when Danish-born drummer Lars Ulrich placed an advertisement in a Los Angeles newspaper, The Recycler, which read, "Drummer looking for other metal musicians to jam with Tygers of Pan Tang, Diamond Head and Iron Maiden." Guitarists James Hetfield and Hugh Tanner of Leather Charm answered the advertisement. Although he had not formed a band, Ulrich asked Metal Blade Records founder Brian Slagel if he could record a song for the label's upcoming compilation album, Metal Massacre. Slagel accepted, and Ulrich recruited Hetfield to sing and play rhythm guitar. The band was officially formed on October 28, 1981, five months after Ulrich and Hetfield first met.The bandname came from Ulrich's friend Ron Quintana, who was brainstorming names for a fanzine and was considering MetalMania or Metallica. After hearing the two names, Ulrich wanted Metallica for his band, so he suggested Quintana use MetalMania instead. Dave Mustaine replied to an advertisement for a lead guitarist; Ulrich and Hetfield recruited him after seeing his expensive guitar equipment. In early 1982, Metallica recorded its first original song, "Hit the Lights", for the Metal Massacre I compilation. Hetfield played bass, rhythm guitar and sang while Lloyd Grant was credited with a guitar solo and Lars Ulrich played drums. Metal Massacre I was released on June 14, 1982; early pressings listed the band incorrectly as "Mettallica", angering the band. The song generated word of mouth and the band played its first live performance on March 14, 1982, at Radio City in Anaheim, California, with newly recruited bassist Ron McGovney. Their first live success came early; they were chosen to open for British heavy metal band Saxon at one gig of their 1982 US tour. This was Metallica's second gig. Metallica recorded its first demo, Power Metal, whose name was inspired by Quintana's early business cards in early 1982. 
Question: What was the full name of the person that asked Brian Slagel if he could record a song?
[EX A]:
Lars Ulrich.
