TASK DEFINITION: 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.
PROBLEM: 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?

SOLUTION: Pickering.

PROBLEM: Passage: Conquistadors often wore steel armour that included chainmail and helmets. The Spanish were sufficiently impressed by the quilted cotton armour of their Maya enemies that they adopted it in preference to their own steel armour. Maya weaponry was not sufficiently powerful to justify the discomfort of wearing European armour. Quilted cotton armour, although still uncomfortably hot, was flexible and weighed much less. The Maya armour was adapted by the Spanish, who used knee-length quilted cotton tunics and Spanish-style caps. Horsemen wore long quilted cotton leg protectors; their horses were also protected with padded cotton armour. After the final push to the Petén lakes in early 1697, the Spanish recorded that they left with their garrison over 50 Dutch- and French-made muskets, three 1-pound (0.45 kg) calibre light cannons (piezas) cast from iron and mounted on carriages, four iron and two bronze pedreros (2-chambered stone-launchers) and six of at least eight bronze light cannons (known as esmiriles). 
Question: Who had four iron and two bronze pedreros?

SOLUTION: the Spanish.

PROBLEM: Passage: In 1987, Doris Duke, considered the wealthiest woman in the world, hires Bernard Lafferty, who lists Elizabeth Taylor and Peggy Lee as former employers on his résumé, as her majordomo. He explains a six-month gap in his employment history was due to "health issues," a euphemism for time spent in rehab to deal with his addiction to alcohol. He assures Doris, who immediately suspects the truth, he is capable of performing his duties without any problems. As Bernard moves in, the viewer can quickly tell he is a little neurotic, first putting portraits of his former employers, Taylor and Lee, in his bedroom, then informing the rest of the staff he is now "Miss Duke's eyes and ears" and demanding they listen to him. Despite Bernard's growing affection for Doris, the brash and often crude Doris thinks little of him, not even remembering how to correctly pronounce his name. However, their situation slowly evolves into a more emotionally intimate but non-physical relationship as Doris returns from a plastic surgery center one evening, drunk and on painkillers, and is aided by Bernard who stays with her through the night. 
Question: What are the last names of the people who develop an emotionally intimate relationship?

SOLUTION:
Duke.
