Problem: Immigration to the United States of Spanish-speaking Cubans began because of Cuba's political instability upon achieving independence. The deposition of Fulgencio Batista's dictatorship and the ascension of Fidel Castro's government in 1959 increased Cuban immigration to the United States, hence there are some one million Cubans in the United States, most settled in southern and central Florida, while other Cubans live in the Northeastern United States; most are fluent in Spanish. In the city of Miami today Spanish is the first language mostly due to Cuban immigration.

The first indigenous group encountered by Columbus were the 250,000 Tainos of Hispaniola who represented the dominant culture in the Greater Antilles and the Bahamas. Within thirty years about 70% of the Tainos had died. They had no immunity to European diseases, so outbreaks of measles and smallpox ravaged their population. Increasing punishment of the Tainos for revolting against forced labour, despite measures put in place by the encomienda, which included religious education and protection from warring tribes, eventually led to the last great Taino rebellion.
What percentage of the Tainos were dead thirty years after contact with Columbus?
A: 70%

Context and question: Key personnel involved in the flight deck include the shooters, the handler, and the air boss. Shooters are naval aviators or Naval Flight Officers and are responsible for launching aircraft. The handler works just inside the island from the flight deck and is responsible for the movement of aircraft before launching and after recovery. The "air boss" (usually a commander) occupies the top bridge (Primary Flight Control, also called primary or the tower) and has the overall responsibility for controlling launch, recovery and "those aircraft in the air near the ship, and the movement of planes on the flight deck, which itself resembles a well-choreographed ballet." The captain of the ship spends most of his time one level below primary on the Navigation Bridge. Below this is the Flag Bridge, designated for the embarked admiral and his staff.
What are 3 key personnel not involved in the flight deck?
Answer: unanswerable

Due to the lack of success lately on the international level, in recent years, Armenia has rebuilt 16 Soviet-era sports schools and furnished them with new equipment for a total cost of $1.9 million. The rebuilding of the regional schools was financed by the Armenian government. $9.3 million has been invested in the resort town of Tsaghkadzor to improve the winter sports infrastructure because of dismal performances at recent winter sports events. In 2005, a cycling center was opened in Yerevan with the aim of helping produce world class Armenian cyclists. The government has also promised a cash reward of $700,000 to Armenians who win a gold medal at the Olympics.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What prize do Armenians receive from the government if they win a gold medal?
Ah, so..
$700,000
