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?
Wood.

Passage: At a London music hall theatre, Richard Hannay is watching a demonstration of the superlative powers of recall of "Mr. Memory" (Wylie Watson) when shots are fired. In the ensuing panic, Hannay finds himself holding a seemingly frightened Annabella Smith, who talks him into taking her back to his flat. There, she tells him that she is a spy, being chased by assassins, and that she has uncovered a plot to steal vital British military information, masterminded by a man with the top joint missing from one of his fingers. She mentions the "39 Steps", but does not explain its meaning.
Later that night Smith, fatally stabbed, bursts into Hannay's bedroom and warns him to flee. He finds a map of the Scottish Highlands clutched in her hand, showing the area around Killin, with a house or farm named "Alt-na-Shellach" circled. He sneaks out of his flat disguised as a milkman to avoid the assassins waiting outside. He then boards the Flying Scotsman express train to Scotland. He learns from a newspaper article (read by a pair of women's undergarment salesmen) that he is the target of a nationwide manhunt for Smith's murder. When he sees the police searching the train, he enters a compartment and kisses the sole occupant, Pamela, in a desperate attempt to hide his face and escape detection. She frees herself from his unwanted embrace and alerts the policemen, who stop the train on the Forth Bridge. Hannay then escapes, hiding behind the bridge's truss. 
Question: What is the full name of the person that the police are searching the train for?
Richard Hannay.

Passage: After the 1994 release of The Downward Spiral, the live band embarked on the Self-Destruct tour in support of the album. Chris Vrenna and James Woolley performed drums and keyboards respectively, Robin Finck replaced Richard Patrick on guitar and bassist Danny Lohner was added to the line-up. The stage set-up consisted of dirty curtains which would be pulled down for visuals shown during songs such as "Hurt". The back of the stage was littered with darker and standing lights, along with very little actual ones. The tour debuted the band's grungy and messy image in which they would come out in ragged clothes slathered in corn starch. The concerts were violent and chaotic, with band members often injuring themselves. They would frequently destroy their instruments at the end of concerts, attack each other, and stage-dive into the crowd.The tour included a set at Woodstock '94 broadcast on Pay-per-view and seen in as many as 24 million homes. The band being covered in mud was a result of pre-concert backstage play, contrary to the belief that it was an attention-grabbing ploy, thus making it difficult for Reznor to navigate the stage: Reznor pushed Lohner into the mud pit as the concert began and saw mud from his hair going into his eyes while performing. Nine Inch Nails was widely proclaimed to have "stolen the show" from its popular contemporaries, mostly classic rock bands, and its fan base expanded. The band received considerable mainstream success thereafter, performing with significantly higher production values and the addition of various theatrical visual elements. Its performance of "Happiness in Slavery" from the Woodstock concert earned the group a Grammy Award for Best Metal Performance in 1995. Entertainment Weekly commented about the band's Woodstock '94 performance: "Reznor unstrings rock to its horrifying, melodramatic core--an experience as draining as it is exhilarating". Despite this acclaim, Reznor attributed his dislike of the concert to its technical difficulties. 
Question: What did the back stage have very little of?

lights.
