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.

Passage: On a train trip, lawyer Richard Grant tells fellow passengers that, based on his long experience both prosecuting and defending murder cases, murder is sometimes justified and a clever man should be able to commit it undetected. He is traveling to the isolated estate of his wealthy client and friend, Gordon Rich; his young adult daughter Barbara surprises him at the train station, where she informs him that she has already been there a week.
Grant's view is soon put to the test. Rich asks him to rewrite his will, including bequests to all his former mistresses (except one who is dead already; she was just 16, and Grant believes it was suicide). When Rich explains that he wants a new will because he intends to marry Barbara, Grant is appalled. He repeats what he said on the train. Rich deserves to be murdered, and if that is what it takes to stop the marriage, Grant will do it and get away with it. Rich retorts that if necessary he will retaliate from beyond the grave.
Grant pleads with his daughter, pointing out the great age difference and Rich's indecent character. But she loves Rich and is adamant. Nor has Tommy Osgood, a young man Barbara had been seeing, been able to change her mind.
At a dinner party that night, Rich announces the wedding and says it will take place in the morning. His longtime girlfriend, Marjorie West, is dismayed, but after the party he assures her that, as usual, he will return to her once he exhausts his obsession with Barbara. He is only marrying Barbara because she would not go to bed with him otherwise.
Rich orders two servants to watch Grant's bungalow on the estate, but Grant uses a cutout mounted on a record player to cast a moving shadow on the curtain to make it appear that he is pacing restlessly, and slips back to the main house. Meanwhile, Rich goes to Barbara's room. He loses control and grabs her roughly; she recoils in disgust and he leaves.
Question: What is the full name of the person who is surprised by someone at the train station?
Richard Grant.

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?
its size.

Passage: When Mary Beekman loses her waitress job, after a fight with her loutish boyfriend, trucker Mike O'Reilly she stands at a bridge on a windy night, losing her pay check through a windblown and leans over the guardrail of the bridge to catch it. Socialite Kenneth Alden catches her, thinking she wants to jump the bridge. He's lost everything that is not already mortgaged. Both down on their luck, they assume that the other is there to jump off the bridge.
Instead, Mary has an idea. If Ken sells shares to a syndicate of his wealthy friends, in a phoney beauty product, they'll have enough money for some clothes to pass Mary off in society, long enough to meet and marry a wealthy bachelor. Then, they can pay everyone back, with interest. The con might work, except that Ken has too much integrity to marry for money to Clarissa (whom he loves for years), and Mary is beginning to see his point when she falls for Pat, who has secrets of his own.
The plot boils over when Mike shows up to blow the lid off. Pat's valet is a thief, who promised not to act foolishly. But he escapes with a stolen Tiara. Meantime Mary thinks to leave as things do not work out, so she shares the taxi to the station with Pat's valet escaping with the Tiara. After a police chase, Mary is hauled off to the station.
It looks like no one is going to end up with anything, but a bad reputation; but, it's not over yet, in this curious, romantic comedy, about the social set, in 1930's America, from Chesterfield films.
Question: What is the last name of the person who lost her check?
Beekman.
