Problem: Umayyad Caliphate:

Muawiyah also encouraged peaceful coexistence with the Christian communities of Syria, granting his reign with "peace and prosperity for Christians and Arabs alike", and one of his closest advisers was Sarjun, the father of John of Damascus. At the same time, he waged unceasing war against the Byzantine Roman Empire. During his reign, Rhodes and Crete were occupied, and several assaults were launched against Constantinople. After their failure, and faced with a large-scale Christian uprising in the form of the Mardaites, Muawiyah concluded a peace with Byzantium. Muawiyah also oversaw military expansion in North Africa (the foundation of Kairouan) and in Central Asia (the conquest of Kabul, Bukhara, and Samarkand).

Who group of Christians rose up against Muawiyah?

A: Mardaites

Problem: The most recent major entrant to the browser market is Chrome, first released in September 2008. Chrome's take-up has increased significantly year by year, by doubling its usage share from 8% to 16% by August 2011. This increase seems largely to be at the expense of Internet Explorer, whose share has tended to decrease from month to month. In December 2011, Chrome overtook Internet Explorer 8 as the most widely used web browser but still had lower usage than all versions of Internet Explorer combined. Chrome's user-base continued to grow and in May 2012, Chrome's usage passed the usage of all versions of Internet Explorer combined. By April 2014, Chrome's usage had hit 45%.
When was Chrome released?

Answer: September 2008

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
For example, consider electronpositron annihilation, in which the rest mass of individual particles is destroyed, but the inertia equivalent of the system of the two particles (its invariant mass) remains (since all energy is associated with mass), and this inertia and invariant mass is carried off by photons which individually are massless, but as a system retain their mass. This is a reversible process the inverse process is called pair creation in which the rest mass of particles is created from energy of two (or more) annihilating photons. In this system the matter (electrons and positrons) is destroyed and changed to non-matter energy (the photons). However, the total system mass and energy do not change during this interaction.
What is the process in which the rest mass of particles is created from energy of two or more annihilating photons?
A: pair creation

Context and question: In the Ottoman Empire, these ideological reforms did not take place and these views did not integrate into common thought until much later. As well, there was no spread of this doctrine within the New World and the advanced civilizations of the Aztec, Maya, Inca, Mohican, Delaware, Huron and especially the Iroquois. The Iroquois philosophy in particular gave much to Christian thought of the time and in many cases actually inspired some of the institutions adopted in the United States: for example, Benjamin Franklin was a great admirer of some of the methods of the Iroquois Confederacy, and much of early American literature emphasized the political philosophy of the natives.
Who was a great admirer of some of the methods of the Iroquois Confederacy?
Answer: Benjamin Franklin

Question: At the end of November, Chopin returned to Paris. He passed the winter in unremitting illness, but gave occasional lessons and was visited by friends, including Delacroix and Franchomme. Occasionally he played, or accompanied the singing of Delfina Potocka, for his friends. During the summer of 1849, his friends found him an apartment in Chaillot, out of the centre of the city, for which the rent was secretly subsidised by an admirer, Princess Obreskoff. Here in June 1849 he was visited by Jenny Lind.
Is there an answer to this question: When did Chopin return to Paris?

Answer: November

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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was Microsoft Windows 3.0's performance comparable to?
Ah, so..
Macintosh platform
