Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Before the introduction of the brown tree snake, Guam was home to several endemic bird species. Among them were the Guam rail (or ko'ko' bird in Chamorro) and the Guam flycatcher, both common throughout the island. Today the flycatcher is entirely extinct while the Guam rail is extinct in the wild but bred in captivity by the Division of Aquatic and Wildlife Resources. The devastation caused by the snake has been significant over the past several decades. As many as twelve bird species are believed to have been driven to extinction. According to many elders, ko'ko' birds were common in Guam before World War II.
What other bird was very common before WWII according to the elders?
A: ko'ko' birds


Context and question: In November 1790, François-Louis-Thibault de Menonville, a member of the National Assembly of France, wrote to Burke, praising Reflections and requesting more "very refreshing mental food" that he could publish. This Burke did in April 1791 when he published A Letter to a Member of the National Assembly. Burke called for external forces to reverse the revolution and included an attack on the late French philosopher Jean-Jacques Rousseau, as being the subject of a personality cult that had developed in revolutionary France. Although Burke conceded that Rousseau sometimes showed "a considerable insight into human nature" he mostly was critical. Although he did not meet Rousseau on his visit to Britain in 1766–7 Burke was a friend of David Hume, with whom Rousseau had stayed. Burke said Rousseau "entertained no principle either to influence of his heart, or to guide his understanding—but vanity"—which he "was possessed to a degree little short of madness". He also cited Rousseau's Confessions as evidence that Rousseau had a life of "obscure and vulgar vices" that was not "chequered, or spotted here and there, with virtues, or even distinguished by a single good action". Burke contrasted Rousseau's theory of universal benevolence and his having sent his children to a foundling hospital: "a lover of his kind, but a hater of his kindred".
What vice-filled book did Hume publish?
Answer: unanswerable


Question: The capital city of Windhoek plays a very important role in Namibia's tourism due to its central location and close proximity to Hosea Kutako International Airport. According to The Namibia Tourism Exit Survey, which was produced by the Millennium Challenge Corporation for the Namibian Directorate of Tourism, 56% of all tourists visiting Namibia during the time period, 2012 - 2013, visited Windhoek. Many of Namibia's tourism related parastatals and governing bodies such as Namibia Wildlife Resorts, Air Namibia and the Namibia Tourism Board as well as Namibia's tourism related trade associations such as the Hospitality Association of Namibia are also all headquartered in Windhoek. There are also a number of notable hotels in Windhoek such as Windhoek Country Club Resort and some international hotel chains also operate in Windhoek, such as Avani Hotels and Resorts and Hilton Hotels and Resorts.

Problem: Federal Bureau of Investigation:

Beginning in the 1940s and continuing into the 1970s, the bureau investigated cases of espionage against the United States and its allies. Eight Nazi agents who had planned sabotage operations against American targets were arrested, and six were executed (Ex parte Quirin) under their sentences. Also during this time, a joint US/UK code-breaking effort (the Venona project)—with which the FBI was heavily involved—broke Soviet diplomatic and intelligence communications codes, allowing the US and British governments to read Soviet communications. This effort confirmed the existence of Americans working in the United States for Soviet intelligence. Hoover was administering this project but failed to notify the Central Intelligence Agency (CIA) until 1952. Another notable case is the arrest of Soviet spy Rudolf Abel in 1957. The discovery of Soviet spies operating in the US allowed Hoover to pursue his longstanding obsession with the threat he perceived from the American Left, ranging from Communist Party of the United States of America (CPUSA) union organizers to American liberals.

How many Nazis were arrested?

A:
Eight
