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?

Ex Output:
its size.

Passage: Tex Hanlon is in charge of a wildly successful and mysterious advertising campaign for "The Three Springs".  People everywhere are curious what the ads refer to, and even Malcolm Tauber the head of the company Hanlon works for, is in the dark. It's revealed that Tauber's assistant (and Hanlon's girlfriend) Gwen Hughes has created some secret sketches of women's fashion for Tex that will be used in the final Three Springs ad. 
However, other forces are at work. Attracted by the attention given the campaign, Renee Beauchamps asks for a chance to begin work with Hanlon. He agrees, but begins to receive threatening notes related to The Three Springs. A passing motorist, Julian Leighton, picks him up and offers him twenty-thousand dollars to spill the secret. Another wealthy man, Alexander Cardovsky, also asks for information. He's later pressured by two thugs, Mr. Warren and Bert to reveal everything. He buys a toy puppet from a poor woman, Jenny, and finds another note in the toy, asking him to meet her. When he does, he discovers Jenny has been murdered, and he's been set up to take the blame. However, Gwen can vouch for Hanlon's whereabouts at the time of the murder.
The next day Tauber is anxious to run the final Three Springs ad. He's upset when Hanlon balks, but grateful Hanlon kept The Three Springs campaign out of his conversation with the police. Hanlon tells Gwen they need to delay because he needs answers to force the criminals out in the open. Gwen convinces him otherwise and arranges to have the final proofs rushed from the printers that evening. Then Hanlon discovers that Renee has been writing the threatening notes, and she claims she'd hope to frighten him into working with her. Renee says she's being followed and must speak with him later. Gwen sees Renee kiss Hanlon goodbye and is furious. 
Question: Who does the passing motorist pick up?

Ex Output:
Tex Hanlon.
