Task: Question Answering
Input (English): Passage: In London, Professor Henry Higgins, a scholar of phonetics, believes that the accent and tone of one's voice determines a person's prospects in society ("Why Can't the English?"). At Covent Garden one evening, he meets Colonel Hugh Pickering, himself a phonetics expert who had come all the way from India to see him. Higgins boasts he could teach anyone to speak so well he could pass them off as a duke or duchess at an embassy ball, even the young woman with a strong Cockney accent named Eliza Doolittle who tries to sell them flowers. Eliza's ambition is to work in a flower shop, but her accent makes that impossible ("Wouldn't It Be Loverly"). The following morning, Eliza shows up at Higgins' home, seeking lessons. Pickering is intrigued and offers to cover all the attendant expenses if Higgins succeeds. Higgins agrees, and describes how women ruin lives ("I'm an Ordinary Man").
Eliza's father, Alfred P. Doolittle, a dustman, learns of his daughter's new residence ("With a Little Bit of Luck"). He shows up at Higgins' house three days later, ostensibly to protect his daughter's virtue, but in reality simply to extract some money from Higgins, and is bought off with £5. Higgins is impressed by the man's honesty, his natural gift for language, and especially his brazen lack of morals. Higgins recommends Alfred to a wealthy American who is interested in morality. 
Eliza endures Higgins' demanding teaching methods and treatment of her personally ("Just You Wait"). She makes little progress, but just as she, Higgins, and Pickering are about to give up, Eliza finally "gets it" ("The Rain in Spain"); she instantly begins to speak with an impeccable upper class accent ("I Could Have Danced All Night"). 
Question: What's the last name of the man that will pay for Eliza's lessons, if successful?
Output (English): Pickering.
