Article: In contrast, Botswana has recently been forced to ban trophy hunting following a precipitous wildlife decline. The numbers of antelope plummeted across Botswana, with a resultant decline in predator numbers, while elephant numbers remained stable and hippopotamus numbers rose. According to the government of Botswana, trophy hunting is at least partly to blame for this, but many other factors, such as poaching, drought and habitat loss are also to blame. Uganda recently did the same, arguing that "the share of benefits of sport hunting were lopsided and unlikely to deter poaching or improve [Uganda's] capacity to manage the wildlife reserves."

Question: What plummeting numbers of this species caused a decline in predator numbers?
Ans: antelope


Article: In 2016, Israel's population was an estimated 8,476,600 million people, of whom 6,345,400 (74.9%) were recorded by the civil government as Jews. 1,760,400 Arabs comprised 20.7% of the population, while non-Arab Christians and people who have no religion listed in the civil registry made up 4.4%. Over the last decade, large numbers of migrant workers from Romania, Thailand, China, Africa, and South America have settled in Israel. Exact figures are unknown, as many of them are living in the country illegally, but estimates run in the region of 203,000. By June 2012, approximately 60,000 African migrants had entered Israel. About 92% of Israelis live in urban areas.

Question: How many Israelis live in urban areas?
Ans: 92%


Article: Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors (at 265.9 pm) in its own plane and six others at a greater distance of 290.6 pm. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 °C. Above 210 °C, the metal becomes brittle again and can be pulverized by beating. Zinc is a fair conductor of electricity. For a metal, zinc has relatively low melting (419.5 °C) and boiling points (907 °C). Its melting point is the lowest of all the transition metals aside from mercury and cadmium.

Question: What is the boiling point of zinc?
Ans: 907 °C


Article: The city slopes gently from the northwest to southeast on a till plain composed largely of glacial and lake clay. The most notable topographical feature in the city is the Detroit Moraine, a broad clay ridge on which the older portions of Detroit and Windsor sit atop, rising approximately 62 feet (19 m) above the river at its highest point. The highest elevation in the city is located directly north of Gorham Playground on the northwest side approximately three blocks south of 8 Mile Road, at a height of 675 to 680 feet (206 to 207 m). Detroit's lowest elevation is along the Detroit River, at a surface height of 572 feet (174 m).

Question: What is the lowest point in Detroit along side?
Ans:
Detroit River
