Q: 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?

A: its size.

Q: Passage: Chicago DEA agent John Hatcher returns from Colombia, where drug dealers killed his partner Chico. As a result of Chico's death and years of dead end work, John retires and heads to his family's home town of Lincoln Heights in suburban Chicago. He visits the local school to meet his old friend and former U.S. Army buddy Max who works there as a football coach and physical education teacher.
As John and Max celebrate their reunion at a club, a gunfight breaks out between local drug dealers and a Jamaican gang at the venue. The gang, known as the Jamaican Posse, is led by a notorious psychotic drug kingpin named Screwface full of West African Vodun and sadism. John arrests one of Screwface's henchmen as the gunfight ends. News of Posse crimes occurring in Chicago and across the United States spread as the Posse expands its operations and recruits more members. The next day, Screwface and his henchmen do a drive-by shooting on the house where John, his sister Melissa, and Melissa's 12-year-old daughter Tracey live. Tracey is injured and hospitalized in critical condition.
John encounters a gangster named Jimmy whom he is forced to kill. A Jamaican gangster named Nesta arrives and is subdued by John, who asks about Screwface. Nesta gives information but tells him to go after Screwface alone and jumps out the window to his death. The next day, John discovers a strange symbol engraved on a carpet, and with the help of Jamaican voodoo and gang expert Leslie, a detective for the Chicago Police Department, he learns that it is an African blood symbol used to mark their crimes. John decides to come out of retirement to join Max in a battle against Screwface. 
Question: What is the first name of the person who visits Max after retiring?

A: John.

Q: Passage: Yale grad Dan Brooks is expected to marry wealthy boss J.L. Higgins' (Charles Bickford) daughter Margaret and join the family box-making business. He is far more interested in racing a horse he owns, Broadway Bill.
Doing poorly at work, Dan and his groom Whitey leave town to enter Bill in the Imperial Derby, but first must find money for the entry fee. He and old pal Professor Pettigrew each try to con the other out of a few bucks, then end up singing the Yale school song to get out of a restaurant tab they cannot pay.
Maggie's younger sister Alice is secretly in love with Dan, so she offers him some money, pawning her belongings. Whitey is beaten up trying to win some in a craps game, and Broadway Bill is carted away because Dan does not pay his feed bill. Dan is jailed, too.
A rich man makes a bet on 100-to-1 shot Bill, leading to false rumors that the horse is a shoo-in. The odds drop fast, but gamblers and a crooked jockey try to make sure their own favorites win the race. Broadway Bill somehow manages to win, but collapses at the finish line and suffers a fatal heart attack.
A saddened Dan takes comfort in deciding to buy and race Broadway Bill II. His enthusiasm persuades Alice and even her dad to lend Dan a hand. 
Question: Who is Margaret's fathers name?

A:
J.L. Higgins.
