Input: Article: The largest single execution in United States history was the hanging of 38 American Indians convicted of murder and rape during the Dakota War of 1862. They were executed simultaneously on December 26, 1862, in Mankato, Minnesota. A single blow from an axe cut the rope that held the large four-sided platform, and the prisoners (except for one whose rope had broken and who had to be re-hanged) fell to their deaths. The second-largest mass execution was also a hanging: the execution of 13 African-American soldiers for taking part in the Houston Riot of 1917. The largest non-military mass execution occurred in one of the original thirteen colonies in 1723, when 26 convicted pirates were hanged in Newport, Rhode Island by order of the Admiralty Court.

Now answer this question: In what state did the largest American mass execution occur?

Output: Minnesota

Input: Article: Hydrogen can be prepared in several different ways, but economically the most important processes involve removal of hydrogen from hydrocarbons. Commercial bulk hydrogen is usually produced by the steam reforming of natural gas. At high temperatures (1000–1400 K, 700–1100 °C or 1300–2000 °F), steam (water vapor) reacts with methane to yield carbon monoxide and H
2.

Now answer this question: The most economical way to prepare hydrogen involves removing it from what?

Output: hydrocarbons

Input: Article: In the original city plan, the interstate buses should also stop at the Central Station. Because of the growth of Brasília (and corresponding growth in the bus fleet), today the interstate buses leave from the older interstate station (called Rodoferroviária), located at the western end of the Eixo Monumental. The Central Bus Station also contains a main metro station. A new bus station was opened in July 2010. It is on Saída Sul (South Exit) near Parkshopping Mall and with its metro station, and it's also an inter-state bus station, used only to leave the Federal District.

Now answer this question: What mall is Brasilia's newest bus station near?

Output:
Parkshopping Mall
