Problem: Karl Popper:

Upon this basis, along with that of the logical content of assertions (where logical content is inversely proportional to probability), Popper went on to develop his important notion of verisimilitude or "truthlikeness". The intuitive idea behind verisimilitude is that the assertions or hypotheses of scientific theories can be objectively measured with respect to the amount of truth and falsity that they imply. And, in this way, one theory can be evaluated as more or less true than another on a quantitative basis which, Popper emphasises forcefully, has nothing to do with "subjective probabilities" or other merely "epistemic" considerations.

What can never be evaluated as more or less true than another on an quantitative basis?

A: unanswerable


Problem: The target audience of natural history was French polite society, evidenced more by the specific discourse of the genre than by the generally high prices of its works. Naturalists catered to polite society's desire for erudition – many texts had an explicit instructive purpose. However, natural history was often a political affair. As E. C. Spary writes, the classifications used by naturalists "slipped between the natural world and the social ... to establish not only the expertise of the naturalists over the natural, but also the dominance of the natural over the social". The idea of taste (le goût) was a social indicator: to truly be able to categorize nature, one had to have the proper taste, an ability of discretion shared by all members of polite society. In this way natural history spread many of the scientific developments of the time, but also provided a new source of legitimacy for the dominant class. From this basis, naturalists could then develop their own social ideals based on their scientific works.
The idea of what quality was a social indicator that provided a new source of legitimacy for the dominant class?

Answer: taste (le goût)


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
One of the most spectacular examples of obligate mutualism is between the siboglinid tube worms and symbiotic bacteria that live at hydrothermal vents and cold seeps. The worm has no digestive tract and is wholly reliant on its internal symbionts for nutrition. The bacteria oxidize either hydrogen sulfide or methane, which the host supplies to them. These worms were discovered in the late 1980s at the hydrothermal vents near the Galapagos Islands and have since been found at deep-sea hydrothermal vents and cold seeps in all of the world's oceans.
From where do the host obtain the hydrogen sulfide or methane?
A: unanswerable


Context and question: During the summers at Nohant, particularly in the years 1839–43, Chopin found quiet, productive days during which he composed many works, including his Polonaise in A-flat major, Op. 53. Among the visitors to Nohant were Delacroix and the mezzo-soprano Pauline Viardot, whom Chopin had advised on piano technique and composition. Delacroix gives an account of staying at Nohant in a letter of 7 June 1842:
Who wrote a letter on June 7, 1842 about a stay in Nohant?
Answer: Delacroix


Question: The consensus of modern scholarship is that the New Testament accounts represent a crucifixion occurring on a Friday, but a Thursday or Wednesday crucifixion have also been proposed. Some scholars explain a Thursday crucifixion based on a "double sabbath" caused by an extra Passover sabbath falling on Thursday dusk to Friday afternoon, ahead of the normal weekly Sabbath. Some have argued that Jesus was crucified on Wednesday, not Friday, on the grounds of the mention of "three days and three nights" in Matthew before his resurrection, celebrated on Sunday. Others have countered by saying that this ignores the Jewish idiom by which a "day and night" may refer to any part of a 24-hour period, that the expression in Matthew is idiomatic, not a statement that Jesus was 72 hours in the tomb, and that the many references to a resurrection on the third day do not require three literal nights.
Is there an answer to this question: On what day is it thought the first part of the New Testament was written?

Answer: unanswerable


Problem: Arena Football League:

In 2001, Jeff Foley published War on the Floor: An Average Guy Plays in the Arena Football League and Lives to Write About It. The book details a journalist's two preseasons (1999 and 2000) as an offensive specialist/writer with the now-defunct Albany Firebirds. The 5-foot-6 (170 cm), self-described "unathletic writer" played in three preseason games and had one catch for −2 yards.

In what year was War on the Floor released?
