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 (34–23 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: The titular Mindhunters are a group of young FBI students who are undergoing training as profilers. Their instructor, experienced profiler Jake Harris, employs a highly realistic training approach by assigning the group variants of real investigations, including elaborate sets, props, and FBI actors to play out each scenario. 
The students include Bobby, a young man with a talent for fixing things; Vince, a wheelchair-using ex-cop who goes nowhere without his gun; Nicole, a smoker who is attempting to quit; Sara, a talented but insecure profiler who is terrified of drowning; Rafe, a very intelligent, caffeine-powered British investigator; Lucas, a supposedly fearless man whose parents were killed when he was a child; and J.D., their leader and Nicole's lover. Nearing the end of their training, the group's over-all morale is high, though Vince discovers that neither he, nor Sara, will make the rank of "Profiler" after secretly reading their training evaluations. 
Question: What are the names of some of the profilers in training?
Example Output: Bobby.

Example Input: Passage: Robert and Cathy Wilson (Robert Donat and Deborah Kerr) are a timid married couple in 1940 London. He is a bookkeeper, she a bored housewife. However, their tedium-filled lives are drastically changed by the war. He enlists in the Royal Navy, while she (against his wishes) joins the Wrens. During the three years the couple are apart, they are transformed, each becoming much more self-confident.
Cathy's assertive new friend, Dizzy Clayton, helps her break out of her shell. She begins going out with Dizzy's cousin, naval architect Richard, who falls in love with her. However, she remains faithful (if unenthusiastically) to her husband.
Meanwhile, Robert toughens up on sea duty and in time becomes a petty officer. His hands are badly burned when his ship is sunk, but he stoically rows in the lifeboat for five days without complaint. He recuperates in a hospital, tended by Elena, a beautiful nurse. On the last night of his stay, he asks her out to dinner. He is attracted to her, but she informs him that she lost her beloved husband only six months earlier, kisses him, and leaves.
Robert and Cathy both receive ten-day leaves, but each dreads being reunited with the dowdy spouse each remembers and being forced back into the dreary life they shared. 
Question: What is the first name of the person who joins the Wrens?
Example Output:
Cathy.
