Input: Charleston, South Carolina
In 1832, South Carolina passed an ordinance of nullification, a procedure by which a state could, in effect, repeal a federal law; it was directed against the most recent tariff acts. Soon, federal soldiers were dispensed to Charleston's forts, and five United States Coast Guard cutters were detached to Charleston Harbor "to take possession of any vessel arriving from a foreign port, and defend her against any attempt to dispossess the Customs Officers of her custody until all the requirements of law have been complied with." This federal action became known as the Charleston incident. The state's politicians worked on a compromise law in Washington to gradually reduce the tariffs.

After South Carolina passed an ordinance of nullification, who was sent to Charleston Harbor?
Output: five United States Coast Guard cutters

Input: Geological history of Earth
The Carboniferous was a time of active mountain building, as the supercontinent Pangea came together. The southern continents remained tied together in the supercontinent Gondwana, which collided with North America-Europe (Laurussia) along the present line of eastern North America. This continental collision resulted in the Hercynian orogeny in Europe, and the Alleghenian orogeny in North America; it also extended the newly uplifted Appalachians southwestward as the Ouachita Mountains. In the same time frame, much of present eastern Eurasian plate welded itself to Europe along the line of the Ural mountains. There were two major oceans in the Carboniferous the Panthalassa and Paleo-Tethys. Other minor oceans were shrinking and eventually closed the Rheic Ocean (closed by the assembly of South and North America), the small, shallow Ural Ocean (which was closed by the collision of Baltica, and Siberia continents, creating the Ural Mountains) and Proto-Tethys Ocean.

What geologic events took place when Pangea combined during the Carboniferous?
Output:
mountain building
