Problem: Dwight D. Eisenhower:

Soviet Premier Nikita Khrushchev announced that a "spy-plane" had been shot down but intentionally made no reference to the pilot. As a result, the Eisenhower Administration, thinking the pilot had died in the crash, authorized the release of a cover story claiming that the plane was a "weather research aircraft" which had unintentionally strayed into Soviet airspace after the pilot had radioed "difficulties with his oxygen equipment" while flying over Turkey. The Soviets put Captain Powers on trial and displayed parts of the U-2, which had been recovered almost fully intact.

According to the cover story, what did the "weather research" pilot have trouble with?
---
A: oxygen equipment

Problem: Polabian Slavs (Wends) settled in parts of England (Danelaw), apparently as Danish allies. Polabian-Pomeranian Slavs are also known to have even settled on Norse age Iceland. Saqaliba refers to the Slavic mercenaries and slaves in the medieval Arab world in North Africa, Sicily and Al-Andalus. Saqaliba served as caliph's guards. In the 12th century, there was intensification of Slavic piracy in the Baltics. The Wendish Crusade was started against the Polabian Slavs in 1147, as a part of the Northern Crusades. Niklot, pagan chief of the Slavic Obodrites, began his open resistance when Lothar III, Holy Roman Emperor, invaded Slavic lands. In August 1160 Niklot was killed and German colonization (Ostsiedlung) of the Elbe-Oder region began. In Hanoverian Wendland, Mecklenburg-Vorpommern and Lusatia invaders started germanization. Early forms of germanization were described by German monks: Helmold in the manuscript Chronicon Slavorum and Adam of Bremen in Gesta Hammaburgensis ecclesiae pontificum. The Polabian language survived until the beginning of the 19th century in what is now the German state of Lower Saxony. In Eastern Germany, around 20% of Germans have Slavic paternal ancestry. Similarly, in Germany, around 20% of the foreign surnames are of Slavic origin.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The men's basketball team has over 1,600 wins, one of only 12 schools who have reached that mark, and have appeared in 28 NCAA tournaments. Former player Austin Carr holds the record for most points scored in a single game of the tournament with 61. Although the team has never won the NCAA Tournament, they were named by the Helms Athletic Foundation as national champions twice. The team has orchestrated a number of upsets of number one ranked teams, the most notable of which was ending UCLA's record 88-game winning streak in 1974. The team has beaten an additional eight number-one teams, and those nine wins rank second, to UCLA's 10, all-time in wins against the top team. The team plays in newly renovated Purcell Pavilion (within the Edmund P. Joyce Center), which reopened for the beginning of the 20092010 season. The team is coached by Mike Brey, who, as of the 201415 season, his fifteenth at Notre Dame, has achieved a 332-165 record. In 2009 they were invited to the NIT, where they advanced to the semifinals but were beaten by Penn State who went on and beat Baylor in the championship. The 201011 team concluded its regular season ranked number seven in the country, with a record of 255, Brey's fifth straight 20-win season, and a second-place finish in the Big East. During the 2014-15 season, the team went 32-6 and won the ACC conference tournament, later advancing to the Elite 8, where the Fighting Irish lost on a missed buzzer-beater against then undefeated Kentucky. Led by NBA draft picks Jerian Grant and Pat Connaughton, the Fighting Irish beat the eventual national champion Duke Blue Devils twice during the season. The 32 wins were the most by the Fighting Irish team since 1908-09.
Which Notre Dame men's basketball player has the record for more points in one game?
A: Austin Carr

Context and question: In 1637 a small party of Puritans reconnoitered the New Haven harbor area and wintered over. In April 1638, the main party of five hundred Puritans who left the Massachusetts Bay Colony under the leadership of the Reverend John Davenport and the London merchant Theophilus Eaton sailed into the harbor. These settlers were hoping to establish a (in their mind) better theological community, with the government more closely linked to the church than the one they left in Massachusetts and sought to take advantage of the excellent port capabilities of the harbor. The Quinnipiacs, who were under attack by neighboring Pequots, sold their land to the settlers in return for protection.
Where did the settlers came from?
Answer: Massachusetts Bay Colony

Question: The end of the war, however, was to cause profound change in Bermuda, though some of those changes would take decades to crystallise. Following the war, with the buildup of Naval and military forces in Bermuda, the primary leg of the Bermudian economy became defence infrastructure. Even after tourism began later in the 19th century, Bermuda remained, in the eyes of London, a base more than a colony. The Crown strengthened its political and economic ties to Bermuda, and the colony's independence on the world stage was diminished.
Is there an answer to this question: What colony caused profound change to the end of the war?

Answer: unanswerable
