In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: Passage: Paraceratherium is an extinct genus of hornless rhinoceros, and one of the largest terrestrial mammals that has ever existed. It lived from the early to late Oligocene epoch (3423 million years ago); its remains have been found across Eurasia between China and the Balkans. It is classified as a member of the hyracodont subfamily Indricotheriinae. Paraceratherium means "near the hornless beast", in reference to Aceratherium, the genus in which the type species P. bugtiense was originally placed.
The exact size of Paraceratherium is unknown because of the incompleteness of the fossils. Its weight is estimated to have been 15 to 20 tonnes (33,000 to 44,000 lb) at most; the shoulder height was about 4.8 metres (15.7 feet), and the length about 7.4 metres (24.3 feet). The legs were long and pillar-like. The long neck supported a skull that was about 1.3 metres (4.3 ft) long. It had large, tusk-like incisors and a nasal incision that suggests it had a prehensile upper lip or proboscis (trunk). The lifestyle of Paraceratherium may have been similar to that of modern large mammals such as the elephants and extant rhinoceroses. Because of its size, it would have had few predators and a slow rate of reproduction. It was a browser, eating mainly leaves, soft plants, and shrubs. It lived in habitats ranging from arid deserts with a few scattered trees to subtropical forests. The reasons for the animal's extinction are unknown, but various factors have been proposed.
Question: What quality of Paraceratherium's probably meant it didn't have many animals trying to eat it?
Example Output: its size.

Example Input: Passage: After her husband Martin completes a four-year prison sentence for insider trading, Emily Taylor drives into a wall in an apparent suicide attempt. Jonathan Banks, her assigned psychiatrist, prescribes a series of antidepressants, but none work. Jonathan contacts Emily's previous psychiatrist, Victoria Siebert, who suggests an experimental new drug, Ablixa. The drug seems to help Emily, but gives her sleepwalking episodes as a side effect.
One night, Emily stabs Martin to death while sleepwalking. Jonathan fights for Emily's acquittal in court. She pleads insanity and is declared not guilty on the condition that she stays in a psychiatric hospital until cleared by Jonathan. The publicity destroys Jonathan's reputation, and his colleagues assume negligence on his part.
Jonathan discovers evidence that Emily is lying; she was not depressed and faked her suicide attempts. He also discovers someone may have profited from Ablixa's fall in stock value. He interviews Emily after administering what he claims is a truth serum that will make her drowsy. Though the serum is actually saline water, she feigns drowsiness, confirming Jonathan's suspicion that she is deceiving him. When he confronts Victoria with his findings, she mails photographs to his wife Deirdre implying he had an affair with Emily. Deirdre leaves him, taking her son with her.
Question: What is the full name of the person who begins sleepwalking?
Example Output: Emily Taylor.

Example Input: 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 is the first name of the person who wants to extract some money from someone?
Example Output:
Alfred.
