Input: Materialism
Despite the large number of philosophical schools and subtle nuances between many, all philosophies are said to fall into one of two primary categories, which are defined in contrast to each other: Idealism, and materialism.[a] The basic proposition of these two categories pertains to the nature of reality, and the primary distinction between them is the way they answer two fundamental questions: "what does reality consist of?" and "how does it originate?" To idealists, spirit or mind or the objects of mind (ideas) are primary, and matter secondary. To materialists, matter is primary, and mind or spirit or ideas are secondary, the product of matter acting upon matter.

What is the second question to ask in order to define the two classes?
Output: "how does it originate?"

Input: Szlachta
The Polish nobility differed in many respects from the nobility of other countries.

What happened to nobility at expense of the king?
Output: actually gained power

Input: Norfolk Island
Norfolk Island was colonised by East Polynesians but was long unpeopled when it was settled by Great Britain as part of its settlement of Australia from 1788. The island served as a convict penal settlement from 6 March 1788 until 5 May 1855, except for an 11-year hiatus between 15 February 1814 and 6 June 1825, when it lay abandoned. On 8 June 1856, permanent civilian residence on the island began when it was settled from Pitcairn Island. In 1913, the UK handed Norfolk over to Australia to administer as an external territory.

What purpose did Norfolk Island serve for the majority of the time from 1788 until 1855?
Output:
a convict penal settlement
