Problem: Please answer a question about the following article about Treaty:
Prior to 1871, the government of the United States regularly entered into treaties with Native Americans but the Indian Appropriations Act of March 3, 1871 (ch. 120, 16 Stat. 563) had a rider (25 U.S.C. § 71) attached that effectively ended the President’s treaty making by providing that no Indian nation or tribe shall be acknowledged as an independent nation, tribe, or power with whom the United States may contract by treaty. The federal government continued to provide similar contractual relations with the Indian tribes after 1871 by agreements, statutes, and executive orders.
Prior to what year did the United States regularly enter into treaties with Native Americans?
A: 1871
Problem: Please answer a question about the following article about Professional wrestling:
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?
A: it has greatly declined in Europe
Problem: Please answer a question about the following article about Light-emitting diode:
LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.
What LEDs have a very steep I/V curve?
A: Nitride-based LEDs
Problem: Please answer a question about the following article about Florida:
The first post-Reconstruction era Republican elected to Congress from Florida was William C. Cramer in 1954 from Pinellas County on the Gulf Coast, where demographic changes were underway. In this period, African Americans were still disenfranchised by the state's constitution and discriminatory practices; in the 19th century they had made up most of the Republican Party. Cramer built a different Republican Party in Florida, attracting local white conservatives and transplants from northern and midwestern states. In 1966 Claude R. Kirk, Jr. was elected as the first post-Reconstruction Republican governor, in an upset election. In 1968 Edward J. Gurney, also a white conservative, was elected as the state's first post-reconstruction Republican US Senator. In 1970 Democrats took the governorship and the open US Senate seat, and maintained dominance for years.
Who was Claude R Kirk 
A:
966 Claude R. Kirk, Jr. was elected as the first post-Reconstruction Republican governor, in an upset election
