Input: Department store
In 1877, John Wanamaker opened the United State's first modern department store in a former Pennsylvania Railroad freight terminal in Philadelphia. Wanamakers was the first department store to offer fixed prices marked on every article and also introduced electrical illumination (1878), the telephone (1879), and the use of pneumatic tubes to transport cash and documents (1880) to the department store business. Subsequent department stores founded in Philadelphia included Strawbridge and Clothier, Gimbels, Lit Brothers, and Snellenbergs.

How were important documents and money transported throughout the store? 
Output: pneumatic tubes

Input: Affirmative action in the United States
UCLA professor Richard H. Sander published an article in the November 2004 issue of the Stanford Law Review that questioned the effectiveness of racial preferences in law schools. He noted that, prior to his article, there had been no comprehensive study on the effects of affirmative action. The article presents a study that shows that half of all black law students rank near the bottom of their class after the first year of law school and that black law students are more likely to drop out of law school and to fail the bar exam. The article offers a tentative estimate that the production of new black lawyers in the United States would grow by eight percent if affirmative action programs at all law schools were ended. Less qualified black students would attend less prestigious schools where they would be more closely matched in abilities with their classmates and thus perform relatively better. Sander helped to develop a socioeconomically-based affirmative action plan for the UCLA School of Law after the passage of Proposition 209 in 1996, which prohibited the use of racial preferences by public universities in California. This change occurred after studies showed that the graduation rate of blacks at UCLA was 41%, compared to 73% for whites.

Which legislative work prohibited the use of racial preferences for admissions in the state of California?
Output: Proposition 209

Input: Marshall Islands
Although the Spanish Empire had a residual claim on the Marshalls in 1874, when she began asserting her sovereignty over the Carolines, she made no effort to prevent the German Empire from gaining a foothold there. Britain also raised no objection to a German protectorate over the Marshalls in exchange for German recognition of Britain's rights in the Gilbert and Ellice Islands. On October 13, 1885, SMS Nautilus under Captain Rötger brought German emissaries to Jaluit. They signed a treaty with Kabua, whom the Germans had earlier recognized as "King of the Ralik Islands," on October 15.

What nation formed a protectorate over the Marshall Islands?
Output: the German Empire
