question:
Passage: Stefen "Stef" Djordjevic is a Serbian American high school defensive back who is gifted in both sports and academics. He is seeking a college football scholarship to escape the economically depressed small western Pennsylvania town of Ampipe and a dead-end job and life working at the mill like his father and brother Greg. He dreams of becoming an engineer right after he graduates from college. Ampipe is a company town whose economy is dominated by the town's main employer, American Pipe & Steel, a steel mill struggling through the downturn of the early 1980s recession. Stef gets through his days with the love of his girlfriend, Lisa Lietzke, and his strong bond with his teammates.
Most of the film takes place after the big football game against undefeated Walnut Heights High School. Ampipe appears headed to win the game, when a fumbled handoff in the closing seconds—as well as Stefen's pass interference penalty earlier in the game—leads to a Walnut Heights victory. Following the game, Coach Burt Nickerson lambastes the fumbler in the locker room, telling him he "quit" the game. When Stefen retorts that the coach himself quit, the coach kicks him off the team.
In the aftermath, disgruntled Ampipe fans vandalize Coach Nickerson's house and yard. Stefen is present and is a reluctant participant, but is nonetheless seen by Nickerson as the vandals flee. From there, Stefen deals with personal battles, including dealing with the coach blackballing him among colleges because of his attitude and participation in the desecration of Nickerson's yard and house. Stefen gets in an argument with Lisa, and his best friend Brian declines a scholarship offer to USC and plans to marry his pregnant girlfriend. 
Question: What's the nickname of the person who gets removed from the team after standing up to the coach?
answer:
Stef.


question:
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?
answer:
its size.
