Here is a question about this article: Many early immigrant groups traveled to America to worship freely, particularly after the English Civil War and religious conflict in France and Germany. They included nonconformists like the Puritans, who were Protestant Christians fleeing religious persecution from the Anglican King of England. Despite a common background, the groups' views on religious toleration were mixed. While some such as Roger Williams of Rhode Island and William Penn of Pennsylvania ensured the protection of religious minorities within their colonies, others like the Plymouth Colony and Massachusetts Bay Colony had established churches. The Dutch colony of New Netherland established the Dutch Reformed Church and outlawed all other worship, though enforcement was sparse. Religious conformity was desired partly for financial reasons: the established Church was responsible for poverty relief, putting dissenting churches at a significant disadvantage.
What is the answer to this question: What were Protestant Christians fleeing from?

So... religious persecution


Here is a question about this article: Fryderyk may have had some piano instruction from his mother, but his first professional music tutor, from 1816 to 1821, was the Czech pianist Wojciech Żywny. His elder sister Ludwika also took lessons from Żywny, and occasionally played duets with her brother. It quickly became apparent that he was a child prodigy. By the age of seven Fryderyk had begun giving public concerts, and in 1817 he composed two polonaises, in G minor and B-flat major. His next work, a polonaise in A-flat major of 1821, dedicated to Żywny, is his earliest surviving musical manuscript.
What is the answer to this question: Who was Frédéric's first professional teacher in music?

So... Wojciech Żywny


Here is a question about this article: Mac OS continued to evolve up to version 9.2.2, including retrofits such as the addition of a nanokernel and support for Multiprocessing Services 2.0 in Mac OS 8.6, though its dated architecture made replacement necessary. Initially developed in the Pascal programming language, it was substantially rewritten in C++ for System 7. From its beginnings on an 8 MHz machine with 128 KB of RAM, it had grown to support Apple's latest 1 GHz G4-equipped Macs. Since its architecture was laid down, features that were already common on Apple's competition, like preemptive multitasking and protected memory, had become feasible on the kind of hardware Apple manufactured. As such, Apple introduced Mac OS X, a fully overhauled Unix-based successor to Mac OS 9. OS X uses Darwin, XNU, and Mach as foundations, and is based on NeXTSTEP. It was released to the public in September 2000, as the Mac OS X Public Beta, featuring a revamped user interface called "Aqua". At US$29.99, it allowed adventurous Mac users to sample Apple's new operating system and provide feedback for the actual release. The initial version of Mac OS X, 10.0 "Cheetah", was released on March 24, 2001. Older Mac OS applications could still run under early Mac OS X versions, using an environment called "Classic". Subsequent releases of Mac OS X included 10.1 "Puma" (2001), 10.2 "Jaguar" (2002), 10.3 "Panther" (2003) and 10.4 "Tiger" (2005).
