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.

Question: Passage: As a result of the Berlin Conference of 1884-1885, the Congo Basin is claimed by King Leopold II of the Belgians, who rules the Congo Free State in personal union with the Kingdom of Belgium. The country is on the verge of bankruptcy, Leopold having borrowed huge sums of money to finance the construction of railways and other infrastructure projects. He sends his envoy Leon Rom to secure the fabled diamonds of Opar. Rom's expedition is ambushed and massacred. A tribal leader, Chief Mbonga, offers Rom the diamonds in exchange for an old enemy: Tarzan.
The man once called "Tarzan", John Clayton III, has left Africa behind and settled down in London with his American-born wife, Jane Porter. He took up his birth name and ancestral family residence as Lord Greystoke. In the eight years since returning from Africa, John's story as Tarzan has become legendary among the Victorian public, although John wants to leave that past behind. Through the British Prime Minister, John is invited by King Leopold to visit Boma and report on the development of the Congo by Belgium; he declines to participate in the perceived publicity stunt.

Answer: What is the first name of the person who sends his envoy to secure diamonds?

Question: Passage: With an average flow at the mouth of about 37,400 cubic feet per second (1,060 m3/s), the Willamette ranks 19th in volume among rivers in the United States and contributes 12 to 15 percent of the total flow of the Columbia River. The Willamette's flow varies considerably season to season, averaging about 8,200 cubic feet per second (230 m3/s) in August to more than 79,000 cubic feet per second (2,200 m3/s) in December.
The U.S. Geological Survey (USGS) operates five stream gauges along the river, at Harrisburg, Corvallis, Albany, Salem, and Portland. The average discharge at the lowermost gauge, near the Morrison Bridge in Portland, was 33,220 cubic feet per second (941 m3/s) between 1972 and 2013. Located at river mile (RM) 12.8 or river kilometer (RK) 20.6, the gauge measures the flow from an area of 11,200 square miles (29,000 km2), roughly 97 percent of the Willamette basin. The highest flow recorded at this station was 420,000 cubic feet per second (11,893 m3/s) on February 9, 1996, during the Willamette Valley Flood of 1996, and the minimum was 4,200 cubic feet per second (120 m3/s) on July 10, 1978. The highest recorded flow of 635,000 cubic feet per second (18,000 m3/s) for the Willamette at a different gauge in Portland occurred during a flood in 1861. This and many other large flows preceded the Flood Control Act of 1936 and dam construction on the Willamette's major tributaries.The river below Willamette Falls, 26.5 miles (42.6 km) from the mouth, is affected by semidiurnal tides, and gauges have detected reverse flows (backwards river flows) upstream from Ross Island at RM 15 (RK 24). The National Weather Service issues tide forecasts for the river at the Morrison Bridge.

Answer: In what month is the flow of the WIllamette the lowest?

Question: Passage: In the city of Pittsburgh where Hamza Perez is seen walking through the streets while narrating about his two recurring life prophecies that would come to him in dreams. One of his dreams was experiencing death at the age of 21, the second was him being in jail. Later he reveals both prophecies had come true. Hamza explains that at the age of 21 he became a Muslim, therefore he experienced a death of all his past doings. According to Hamza, one day while he was on the street smoking marijuana, a sheikh approached him to talk about Islam and that is when he knew things were going to change.
While Hamza visits his brother Suliman to cook Boricua Halal cooking (Puerto Rican Kosher cooking) the two brothers talk about their cultural hybridity and how they communicate through Arabic spanglish ebonics since they don't speak Arabic, English, or Spanish fluently. In a family gathering, Hamza and Suliman's mother Gladys expresses her hesitation about the religion since both brothers were brought up in a Catholic home and attended private Catholic school. Gladys reveals that Hamza's birth given name is Jason, and although she is still unsure about the religion Gladys has accepts the decision of her two sons. The two brothers travel to Harlem to conduct an interview for a radio station where they talk about their music and religious message. While still in New York, Hamza visits the projects where he reaches out to young since he works for a social service agency as an anti-drug counselor.

Answer:
What are the Muslim names of Gladys' sons?
