Article: The interceptor aircraft (or simply interceptor) is a type of fighter aircraft designed specifically to intercept and destroy enemy aircraft, particularly bombers, usually relying on high speed and altitude capabilities. A number of jet interceptors such as the F-102 Delta Dagger, the F-106 Delta Dart, and the MiG-25 were built in the period starting after the end of World War II and ending in the late 1960s, when they became less important due to the shifting of the strategic bombing role to ICBMs. Invariably the type is differentiated from other fighter aircraft designs by higher speeds and shorter operating ranges, as well as much reduced ordnance payloads.

Question: What kind of aircraft is used to intercept and destroy other aircraft?
Ans: The interceptor aircraft

Here is a question about this article: The mandolin orchestras never completely went away, however. In fact, along with all the other musical forms the mandolin is involved with, the mandolin ensemble (groups usually arranged like the string section of a modern symphony orchestra, with first mandolins, second mandolins, mandolas, mandocellos, mando-basses, and guitars, and sometimes supplemented by other instruments) continues to grow in popularity. Since the mid-nineties, several public-school mandolin-based guitar programs have blossomed around the country, including Fretworks Mandolin and Guitar Orchestra, the first of its kind. The national organization, Classical Mandolin Society of America, founded by Norman Levine, represents these groups. Prominent modern mandolinists and composers for mandolin in the classical music tradition include Samuel Firstman, Howard Fry, Rudy Cipolla, Dave Apollon, Neil Gladd, Evan Marshall, Marilynn Mair and Mark Davis (the Mair-Davis Duo), Brian Israel, David Evans, Emanuil Shynkman, Radim Zenkl, David Del Tredici and Ernst Krenek.
What is the answer to this question: Who found the Classical Mandolin Society of America?
****
So... Norman Levine

The problem: Answer a question about this article:
Association football is played in accordance with a set of rules known as the Laws of the Game. The game is played using a spherical ball of 68.569.5 cm (27.027.4 in) circumference, known as the football (or soccer ball). Two teams of eleven players each compete to get the ball into the other team's goal (between the posts and under the bar), thereby scoring a goal. The team that has scored more goals at the end of the game is the winner; if both teams have scored an equal number of goals then the game is a draw. Each team is led by a captain who has only one official responsibility as mandated by the Laws of the Game: to be involved in the coin toss prior to kick-off or penalty kicks.
What would you describe the shape of the football?
****
The answer: spherical

Problem: Please answer a question about the following article about Franco-Prussian War:
The German states proclaimed their union as the German Empire under the Prussian king, Wilhelm I, uniting Germany as a nation-state. The Treaty of Frankfurt of 10 May 1871 gave Germany most of Alsace and some parts of Lorraine, which became the Imperial territory of Alsace-Lorraine (Reichsland Elsa-Lothringen).The German conquest of France and the unification of Germany upset the European balance of power, that had existed since the Congress of Vienna in 1815 and Otto von Bismarck maintained great authority in international affairs for two decades. French determination to regain Alsace-Lorraine and fear of another Franco-German war, along with British apprehension about the balance of power, became factors in the causes of World War I.
Following the unification of Germany, who maintained great authority in international affairs for two decades?
A: Otto von Bismarck

Historians trace the earliest Baptist church back to 1609 in Amsterdam, with John Smyth as its pastor. Three years earlier, while a Fellow of Christ's College, Cambridge, he had broken his ties with the Church of England. Reared in the Church of England, he became "Puritan, English Separatist, and then a Baptist Separatist," and ended his days working with the Mennonites. He began meeting in England with 6070 English Separatists, in the face of "great danger." The persecution of religious nonconformists in England led Smyth to go into exile in Amsterdam with fellow Separatists from the congregation he had gathered in Lincolnshire, separate from the established church (Anglican). Smyth and his lay supporter, Thomas Helwys, together with those they led, broke with the other English exiles because Smyth and Helwys were convinced they should be baptized as believers. In 1609 Smyth first baptized himself and then baptized the others.

Who was the pastor of the earliest Baptist church?
Answer:
John Smyth
