Input: Read this: After the expulsion of the German population ethnic Russians, Belarusians, and Ukrainians were settled in the northern part. In the Soviet part of the region, a policy of eliminating all remnants of German history was pursued. All German place names were replaced by new Russian names. The exclave was a military zone, which was closed to foreigners; Soviet citizens could only enter with special permission. In 1967 the remnants of Konigsberg Castle were demolished on the orders of Leonid Brezhnev to make way for a new "House of the Soviets".
Question: Once the German populations was removed, what three groups settled into the nothern area?

Output: ethnic Russians, Belarusians, and Ukrainians

QUES: There are more than 100 freshwater fish species, varying from the giant European catfish (in the Tagus International Natural Park) to some small and endemic species that live only in small lakes (along the western portion of country, for example). Some of these rare and specific species are highly endangered because of habitat loss, pollution and drought. Up-welling along the west coast of Portugal makes the sea extremely rich in nutrients and diverse species of marine fish; the Portuguese marine waters are one of the richest in the world. Marine fish species are more common, and include thousands of species, such as the sardine (Sardina pilchardus), tuna and Atlantic mackerel. Bioluminescent species are also well represented (including species in different colour spectrum and forms), like the glowing plankton that are possible to observe in some beaches.

How many freshwater fish species can be found in Portugal?
What is the answer?
ANS: more than 100

QUES: Originating as a popular form of entertainment in 19th-century Europe and later as a sideshow exhibition in North American traveling carnivals and vaudeville halls, professional wrestling grew into a standalone genre of entertainment with many diverse variations in cultures around the globe, and is now considered a multimillion-dollar entertainment industry. While it has greatly declined in Europe, in North America it has experienced several different periods of prominent cultural popularity during its century and a half of existence. The advent of television gave professional wrestling a new outlet, and wrestling (along with boxing) was instrumental in making pay-per-view a viable method of content delivery.
What part of the world has wrestling become less popular in?

ANS: it has greatly declined in Europe

In 2001, Apple introduced Mac OS X, based on Darwin and NEXTSTEP; its new features included the Dock and the Aqua user interface. During the transition, Apple included a virtual machine subsystem known as Classic, allowing users to run Mac OS 9 applications under Mac OS X 10.4 and earlier on PowerPC machines. Apple introduced Mac OS X 10.8 in February, and it was made available in the summer of 2012. Mountain Lion includes many new features, such as Mission Control, the Mac App Store (available to Mac OS X v10.6.6 "Snow Leopard." users by software update), Launchpad, an application viewer and launcher akin to the iOS Home Screen, and Resume, a feature similar to the hibernate function found in Microsoft Windows. The most recent version is OS X El Capitan . In addition to Mavericks, all new Macs are bundled with assorted Apple-produced applications, including iLife, the Safari web browser and the iTunes media player. Apple introduced Mavericks at WWDC 2013 in June, and released it on October 15 of that year. It is free of charge to everyone running Snow Leopard or later and is compatible with most Macs from 2007 and later. Mavericks brought a lot of the iOS apps, functions, and feel to the Mac as well as better multi display support, iBooks, Maps, app nap, and other upgrades to improve performance and battery life.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What computers is Maverick incompatible with?
Ah, so.. unanswerable

Question: These symmetries are represented by functions. Each of these functions sends a point in the square to the corresponding point under the symmetry. For example, r1 sends a point to its rotation 90 clockwise around the square's center, and fh sends a point to its reflection across the square's vertical middle line. Composing two of these symmetry functions gives another symmetry function. These symmetries determine a group called the dihedral group of degree 4 and denoted D4. The underlying set of the group is the above set of symmetry functions, and the group operation is function composition. Two symmetries are combined by composing them as functions, that is, applying the first one to the square, and the second one to the result of the first application. The result of performing first a and then b is written symbolically from right to left as
Try to answer this question if possible: Both symmetries are applied to what?
Answer: unanswerable
