Problem: Background: Jumbo (about Christmas 1860 - September 15, 1885), also known as Jumbo the Elephant and Jumbo the Circus Elephant, was a 19th-century male African bush elephant born in Sudan. Jumbo was exported to Jardin des Plantes, a zoo in Paris and then transferred in 1865 to London Zoo in England. Despite public protest, Jumbo was sold to P. T. Barnum, who took him to the United States for exhibition in March 1882. The giant elephant's name has spawned the common word, "jumbo", meaning large in size.
Context: Jumbo was born at about Christmas 1860 in the Sudan and, after his mother was killed by hunters, the infant Jumbo was captured by Sudanese elephant hunter, Taher Sheriff. The calf was sold to Lorenzo Casanova, an Italian animal dealer and explorer. Casanova transported the animals that he had bought north from Sudan to Suez, and then across the Mediterranean to Trieste. This collection was sold to Gottlieb Christian Kreutzberg's "Menagerie Kreutzberg" in Germany. Soon after, the elephant was imported to France and kept in the Paris zoo, Jardin des Plantes. In 1865 he was transferred to London Zoo, arriving on 26 June, and becoming famous for giving rides to visitors, especially children. The London zookeeper association leader Anoshan Anathajeyasri gave Jumbo his name; it is likely a variation of one of two Swahili words: jambo, which means "hello"; or jumbe, meaning "chief". If Anoshan Anathajeyasri was from India, it is possible that he named Jumbo after a gigantic rose-apple tree, called jambu (which at that time would be transliterated as 'jumboo')which grows on the mythical Mount Meru and whose fruits were said to be as large as elephants. While at London, Jumbo broke both tusks, and when they regrew, ground them down against the stonework of his enclosure. His keeper at London was Matthew Scott, whose 1885 autobiography details his life with Jumbo. Jumbo was sold in February 1882 to the Barnum & Bailey Circus for PS2,000. There was popular objection when Barnum's proposal became known; 100,000 school children wrote to Queen Victoria begging her not to sell the elephant. Despite a lawsuit against the Zoological Gardens alleging the sale was in violation of multiple zoo bylaws, and the zoo's attempt to renege on the sale, the court upheld the sale and Barnum refused to sell Jumbo back. Matthew Scott elected to go with Jumbo to the USA. In New York, Barnum exhibited the elephant at Madison Square Garden, earning enough in three weeks from the enormous crowds to recoup the money he spent to buy the animal. In the 31-week season, the circus earned $1.75M, largely due to its star attraction. On 30 May 1884, Jumbo was one of Barnum's 21 elephants that crossed the Brooklyn Bridge to prove that it was safe after 12 people died during a stampede caused by mass panic over collapse fears a year earlier.
Question: Why was he grinding his tusks? Was he going crazy or sick?
Answer:

Problem: Background: Born in Dallas, Texas, into a family of Mexican ancestry, Trevino was raised by his mother, Juanita Trevino, and his grandfather, Joe Trevino, a gravedigger. Trevino never knew his father, Joseph Trevino, who left when his son was small. Trevino's childhood consisted of attending school occasionally and working to earn money for the family. At age 5, he started working in the cotton fields.
Context: At age 49 in the 1989 Masters, Trevino shot an opening round five-under-par 67 to become the oldest man ever to lead the field after a round in the tournament. It came despite Trevino's words 20 years earlier, when he said after the 1969 Masters: "Don't talk to me about the Masters. I'm never going to play there again. They can invite me all they want, but I'm not going back. It's just not my type of course." Trevino said that he felt uncomfortable with the atmosphere at the Augusta National club and that he disliked the course because his style of play, where he liked to fade shots left to right, was not suited to the course. Trevino did not accept invitations to the Masters in 1970, 1971 and again in 1974. In 1972, after forgoing the previous two Masters tournaments, he stored his shoes and other items in the trunk of his car, rather than use the locker room facilities in the clubhouse. Trevino complained that had he not qualified as a player, the club would not have let him onto the grounds except through the kitchen. But he later described his boycott of the Masters as "the greatest mistake I've made in my career" and called Augusta National "the eighth wonder of the world." After his opening round of 67 in the 1989 Masters, Trevino finished the tournament tied for 18th place. His best finish at the Masters was a tie for 10th place twice: in 1975 and in 1985.
Question: How old was he?
Answer: age 49

Problem: Background: Count Dracula is the title character of Bram Stoker's 1897 gothic horror novel Dracula. He is considered to be both the prototypical and the archetypal vampire in subsequent works of fiction. He is also depicted in the novel to be the origin of werewolf legends. Some aspects of the character are believed to have been inspired by the 15th-century Wallachian Prince Vlad the Impaler, who was also known as Dracula.
Context: Count Dracula is portrayed in the novel using many different supernatural abilities, and is believed to have gained his abilities through dealings with the Devil. Chapter 18 of the novel describes many of the abilities, limitations and weaknesses of vampires and Dracula in particular. Dracula has superhuman strength which, according to Van Helsing, is equivalent to that of 20 strong men. He does not cast a shadow or have a reflection from mirrors. He is immune to conventional means of attack; a sailor tries to stab him in the back with a knife, but the blade goes through his body as though it is air. Why Harker's and Morris' physical attacks are able to harm him in other parts of the book is never explained although it is noteworthy that the failed stabbing by the sailor occurred at night and the successful attacks were during daylight hours. The Count can defy gravity to a certain extent and possesses superhuman agility, able to climb vertical surfaces upside down in a reptilian manner. He can travel onto "unhallowed" ground such as the graves of suicides and those of his victims. He has powerful hypnotic, telepathic and illusionary abilities. He also has the ability to "within limitations" vanish and reappear elsewhere at will. If he knows the path, he can come out from anything or into anything regardless of how close it is bound even if it is fused with fire. He has amassed cunning and wisdom throughout centuries, and he is unable to die by the mere passing of time alone. He can command animals such as rats, owls, bats, moths, foxes and wolves. However, his control over these animals is limited, as seen when the party first enters his house in London. Although Dracula is able to summon thousands of rats to swarm and attack the group, Holmwood summons his trio of terriers to do battle with the rats. The dogs prove very efficient rat killers, suggesting they are Manchester terriers trained for that purpose. Terrified by the dogs' onslaught, the rats flee and any control which Dracula had over them is gone. Dracula can also manipulate the weather and, within his range, is able to direct the elements, such as storms, fog and mist.
Question: Is that all the power he have ?
Answer:
The Count can defy gravity to a certain extent and possesses superhuman agility, able to climb vertical surfaces upside down in a reptilian manner.
