Problem: Indigenous peoples of the Americas:

Following years of mistreatment, the Tainos began to adopt suicidal behaviors, with women aborting or killing their infants and men jumping from the cliffs or ingesting untreated cassava, a violent poison. Eventually, a Taino Cacique named Enriquillo managed to hold out in the Baoruco Mountain Range for thirteen years, causing serious damage to the Spanish, Carib-held plantations and their Indian auxiliaries. Hearing of the seriousness of the revolt, Emperor Charles V (also King of Spain) sent captain Francisco Barrionuevo to negotiate a peace treaty with the ever-increasing number of rebels. Two months later, after consultation with the Audencia of Santo Domingo, Enriquillo was offered any part of the island to live in peace.

How many years was a Tainos Cacique able to hold ou in the Baoruco Mountain Range?
---
A: thirteen

Problem: The evolution of seed plants and later angiosperms appears to be the result of two distinct rounds of whole genome duplication events. These occurred at 319 million years ago and 192 million years ago. Another possible whole genome duplication event at 160 million years ago perhaps created the ancestral line that led to all modern flowering plants. That event was studied by sequencing the genome of an ancient flowering plant, Amborella trichopoda, and directly addresses Darwin's "abominable mystery."
When did the first whole genome duplication event occur?
---
Answer: 319 million years ago

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Parallel to the military developments emerged also a constantly more elaborate chivalric code of conduct for the warrior class. This new-found ethos can be seen as a response to the diminishing military role of the aristocracy, and gradually it became almost entirely detached from its military origin. The spirit of chivalry was given expression through the new (secular) type of chivalric orders; the first of these was the Order of St. George, founded by Charles I of Hungary in 1325, while the best known was probably the English Order of the Garter, founded by Edward III in 1348.
In what year was the Order of St. George founded?
A: 1325

Context and question: The term comics refers to the comics medium when used as an uncountable noun and thus takes the singular: "comics is a medium" rather than "comics are a medium". When comic appears as a countable noun it refers to instances of the medium, such as individual comic strips or comic books: "Tom's comics are in the basement."
The term comedies refers to what?
Answer: unanswerable

Question: Some scientific studies suggest that ozone depletion may have a dominant role in governing climatic change in Antarctica (and a wider area of the Southern Hemisphere). Ozone absorbs large amounts of ultraviolet radiation in the stratosphere. Ozone depletion over Antarctica can cause a cooling of around 6 C in the local stratosphere. This cooling has the effect of intensifying the westerly winds which flow around the continent (the polar vortex) and thus prevents outflow of the cold air near the South Pole. As a result, the continental mass of the East Antarctic ice sheet is held at lower temperatures, and the peripheral areas of Antarctica, especially the Antarctic Peninsula, are subject to higher temperatures, which promote accelerated melting. Models also suggest that the ozone depletion/enhanced polar vortex effect also accounts for the recent increase in sea ice just offshore of the continent.
Is there an answer to this question: What can the wind changes due to cooling cause in the Antarctic ice?

Answer: accelerated melting

Problem: Geological history of Earth:

A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was glaciated throughout the period, though it is uncertain if the ice sheets were a holdover from the Devonian or not. These conditions apparently had little effect in the deep tropics, where lush coal swamps flourished within 30 degrees of the northernmost glaciers. A mid-Carboniferous drop in sea-level precipitated a major marine extinction, one that hit crinoids and ammonites especially hard. This sea-level drop and the associated unconformity in North America separate the Mississippian Period from the Pennsylvanian period.

The Pennsylvania period is separated by the drop in Carboniferous era sea levels from what other period?
---
A:
Mississippian Period
