Problem: Bermuda:

The only indigenous mammals of Bermuda are five species of bats, all of which are also found in the eastern United States: Lasionycteris noctivagans, Lasiurus borealis, Lasiurus cinereus, Lasiurus seminolus and Perimyotis subflavus. Other commonly known fauna of Bermuda include its national bird, the Bermuda petrel or cahow. It was rediscovered in 1951 after having been thought extinct since the 1620s. It is important as an example of a Lazarus species. The government has a programme to protect it, including restoration of a habitat area. The Bermuda rock skink was long thought to have been the only indigenous land vertebrate of Bermuda, discounting the marine turtles that lay their eggs on its beaches. Recently through genetic DNA studies, scientists have discovered that a species of turtle, the diamondback terrapin, previously thought to have been introduced, pre-dated the arrival of humans in the archipelago. As this species spends most of its time in brackish ponds, some question whether it should be classified as a land vertebrate to compete with the skink's unique status.

What animal has held the title of Bermuda's only native land vertabrate?

A: Bermuda rock skink

Problem: Microsoft Windows 3.0 was released in May 1990, and according to a common saying at the time "Windows was not as good as Macintosh, but it was good enough for the average user". Though still a graphical wrapper that relied upon MS-DOS, 3.0 was the first iteration of Windows which had a feature set and performance comparable to the much more expensive Macintosh platform. It also did not help matters that during the previous year Jean-Louis Gassee had steadfastly refused to lower the profit margins on Mac computers. Finally, there was a component shortage that rocked the exponentially-expanding PC industry in 1989, forcing Apple USA head Allan Loren to cut prices which dropped Apple's margins.
Who was Microsoft Windows 3.0 commonly said to be good enough for?

Answer: the average user

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Though it is the most played local derby in the history of La Liga, it is also the most unbalanced, with Barcelona overwhelmingly dominant. In the primera division league table, Espanyol has only managed to end above Barca on three occasions from 80 seasons (19282015) and the only all-Catalan Copa del Rey final was won by Barca in 1957. Espanyol has the consolation of achieving the largest margin win with a 60 in 1951, while Barcelona's biggest win was 50 on five occasions (in 1933, 1947, 1964, 1975 and 1992). Espanyol achieved a 21 win against Barca during the 200809 season, becoming the first team to defeat Barcelona at Camp Nou in their treble-winning season.
What team has beaten Barcelona three times in 80 seasons?
A: Espanyol

Context and question: Despite yet another offer from the Institute for Advanced Study, Feynman rejected the Institute on the grounds that there were no teaching duties: Feynman felt that students were a source of inspiration and teaching was a diversion during uncreative spells. Because of this, the Institute for Advanced Study and Princeton University jointly offered him a package whereby he could teach at the university and also be at the institute.[citation needed] Feynman instead accepted an offer from the California Institute of Technology (Caltech)and as he says in his book Surely You're Joking Mr. Feynman!because a desire to live in a mild climate had firmly fixed itself in his mind while he was installing tire chains on his car in the middle of a snowstorm in Ithaca.
Where did Feynman receive no inspiration?
Answer: unanswerable

Question: Dawa Norbu argues that modern Chinese Communist historians tend to be in favor of the view that the Ming simply reappointed old Yuan dynasty officials in Tibet and perpetuated their rule of Tibet in this manner. Norbu writes that, although this would have been true for the eastern Tibetan regions of Amdo and Kham's "tribute-cum-trade" relations with the Ming, it was untrue if applied to the western Tibetan regions of U-Tsang and Ngari. After the Phagmodrupa Changchub Gyaltsen, these were ruled by "three successive nationalistic regimes," which Norbu writes "Communist historians prefer to ignore."
Is there an answer to this question: Who believed the Ming reappointed old Yuan dynasty officials in Tibet?

Answer: Dawa Norbu

Question: According to the tradition, Virgil traveled to Greece in about 19 BC to revise the Aeneid. After meeting Augustus in Athens and deciding to return home, Virgil caught a fever while visiting a town near Megara. After crossing to Italy by ship, weakened with disease, Virgil died in Brundisium harbor on September 21, 19 BC. Augustus ordered Virgil's literary executors, Lucius Varius Rufus and Plotius Tucca, to disregard Virgil's own wish that the poem be burned, instead ordering it published with as few editorial changes as possible. As a result, the text of the Aeneid that exists may contain faults which Virgil was planning to correct before publication. However, the only obvious imperfections are a few lines of verse that are metrically unfinished (i.e. not a complete line of dactylic hexameter). Some scholars have argued that Virgil deliberately left these metrically incomplete lines for dramatic effect. Other alleged imperfections are subject to scholarly debate.
Is there an answer to this question: What date did Virgil die?

Answer:
September 21, 19 BC
