In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Hillsboro () is the fifth-largest city in the State of Oregon and is the county seat of Washington County. Lying in the Tualatin Valley on the west side of the Portland metropolitan area, the city hosts many high-technology companies, such as Intel, that comprise what has become known as the Silicon Forest. At the 2010 Census, the city's population was 91,611.For thousands of years before the arrival of European-American settlers, the Atfalati tribe of the Kalapuya lived in the Tualatin Valley near the later site of Hillsboro. The climate, moderated by the Pacific Ocean, helped make the region suitable for fishing, hunting, food gathering, and agriculture. Settlers founded a community here in 1842, later named after David Hill, an Oregon politician. Transportation by riverboat on the Tualatin River was part of Hillsboro's settler economy. A railroad reached the area in the early 1870s and an interurban electric railway about four decades later. These railways, as well as highways, aided the slow growth of the city to about 2,000 people by 1910 and about 5,000 by 1950, before the arrival of high-tech companies in the 1980s.
Hillsboro has a council–manager government consisting of a city manager and a city council headed by a mayor. In addition to high-tech industry, sectors important to Hillsboro's economy are health care, retail sales, and agriculture, including grapes and wineries. The city operates more than twenty parks and the mixed-use Hillsboro Stadium, and ten sites in the city are listed on the National Register of Historic Places (NRHP). Modes of transportation include private vehicles, public buses and light rail, and aircraft using the Hillsboro Airport. The city is home to Pacific University's Health Professions Campus. Notable residents include two Oregon governors.
What is on the east side of Hillsboro?

Passage: Nathan Ellis, a 9-year-old maths prodigy, has just lost his father in a car accident. Nathan is diagnosed with autism early in the film, and his father was the only one who was able to connect normally with him. Although Nathan values his mother, Julie, he shuns any physical contact with her and treats her as more of a caretaker than a parent. Wanting to make sure Nathan isn't distracted from his studies, Julie enrolls him in advanced classes at a new school. There, he comes under the tutelage of teacher Martin, also a math genius, who now suffers from multiple sclerosis. Martin sees himself in Nathan, once a promising young mind in the field of mathematics, who gave it all up once he was diagnosed with his illness.
Seven years later, Martin is preparing Nathan to compete for a place in the International Mathematical Olympiad, a prestigious high school competition consisting of the world's best young mathematicians. This year, it is to be held at Cambridge, after a two-week math camp in Taiwan where the students will study for the test that determines the winners. Nathan fears he's not good enough to qualify but ends up doing well enough to accompany 15 other British teenagers to Taiwan.
Suddenly thrust out of his comfort zone, Nathan finds himself no longer the smartest math whiz in the room, and his social anxieties nearly paralyze his performance. He has trouble reading the social cues of others and flinches at the slightest physical contact with another person. Nathan is paired with a female Chinese student, Zhang Mei, who slowly helps him adjust to his new surroundings and helps him fight through his fears. By the skin of their teeth, Nathan and Zhang make the cut to compete in Cambridge.
Who comes under the tutelage of a math genius teacher?

Passage: In the 14th century, diplomatic contact continued between the Franks and the Mongols, until the Ilkhanate dissolved in the 1330s, and the ravages of the Black Death in Europe caused contact with the East to be severed. A few marital alliances between Christian rulers and the Mongols of the Golden Horde continued, such as when the Byzantine emperor Andronicus II gave daughters in marriage to Toqto'a (d. 1312) and later to his successor Uzbek (1312–1341).After Abu Sa'id, relations between Christian princes and the Ilkhanate became very sparse. Abu Sa'id died in 1335 with neither heir nor successor, and the Ilkhanate lost its status after his death, becoming a plethora of little kingdoms run by Mongols, Turks, and Persians.In 1336, an embassy to the French Pope Benedict XII in Avignon was sent by Toghun Temür, the last Yuan emperor in Dadu. The embassy was led by two Genoese travelers in the service of the Mongol emperor, who carried letters representing that the Mongols had been eight years (since Archbishop John of Montecorvino's death) without a spiritual guide, and earnestly desired one. Pope Benedict appointed four ecclesiastics as his legates to the khan's court. In 1338, a total of 50 ecclesiastics were sent by the pope to Peking, among them John of Marignolli, who returned to Avignon in 1353 with a letter from the Yuan emperor to Pope Innocent VI. But soon, the Han Chinese rose up and drove the Mongols out of China, establishing the Ming Dynasty in 1368. By 1369, all foreign influences, from Mongols to Christians, Manichaeans, and Buddhists, were expelled by the Ming Dynasty.
In the early 15th century, Timur (Tamerlane) resumed relations with Europe, attempting to form an alliance against the Egyptian Mamluks and the Ottoman Empire, and engaged in communications with Charles VI of France and Henry III of Castile, but died in 1405.

What two things did Abu Sa'id not have when he died?
