Input: Database
A DBMS has evolved into a complex software system and its development typically requires thousands of human years of development effort.[a] Some general-purpose DBMSs such as Adabas, Oracle and DB2 have been undergoing upgrades since the 1970s. General-purpose DBMSs aim to meet the needs of as many applications as possible, which adds to the complexity. However, the fact that their development cost can be spread over a large number of users means that they are often the most cost-effective approach. However, a general-purpose DBMS is not always the optimal solution: in some cases a general-purpose DBMS may introduce unnecessary overhead. Therefore, there are many examples of systems that use special-purpose databases. A common example is an email system that performs many of the functions of a general-purpose DBMS such as the insertion and deletion of messages composed of various items of data or associating messages with a particular email address; but these functions are limited to what is required to handle email and don't provide the user with all of the functionality that would be available using a general-purpose DBMS.

How long can it take to create a DBMS?
Output: thousands of human years

Input: Alaska
The climate of Western Alaska is determined in large part by the Bering Sea and the Gulf of Alaska. It is a subarctic oceanic climate in the southwest and a continental subarctic climate farther north. The temperature is somewhat moderate considering how far north the area is. This region has a tremendous amount of variety in precipitation. An area stretching from the northern side of the Seward Peninsula to the Kobuk River valley (i. e., the region around Kotzebue Sound) is technically a desert, with portions receiving less than 10 in (25 cm) of precipitation annually. On the other extreme, some locations between Dillingham and Bethel average around 100 in (250 cm) of precipitation.

Which area of Western Alaska is techincally a desert?
Output: the region around Kotzebue Sound

Input: Canon law
Other churches in the Anglican Communion around the world (e.g., the Episcopal Church in the United States, and the Anglican Church of Canada) still function under their own private systems of canon law.

What do extant churches of the Anglican Communion still operate with?
Output: their own private systems of canon law

Input: Hunting
In the 19th century, southern and central European sport hunters often pursued game only for a trophy, usually the head or pelt of an animal, which was then displayed as a sign of prowess. The rest of the animal was typically discarded. Some cultures, however, disapprove of such waste. In Nordic countries, hunting for trophies wasand still isfrowned upon. Hunting in North America in the 19th century was done primarily as a way to supplement food supplies, although it is now undertaken mainly for sport.[citation needed] The safari method of hunting was a development of sport hunting that saw elaborate travel in Africa, India and other places in pursuit of trophies. In modern times, trophy hunting persists and is a significant industry in some areas.[citation needed]

What types of trophies would hunters keep as trophies to be displayed as a sign of their prowess?
Output:
the head or pelt of an animal
