The 1967 Detroit riot, also known as the 12th Street riot or the 1967 Detroit rebellion, was one of 159 race riots that swept cities in the United States during the 'Long hot summer of 1967'. This riot was a violent public disorder that turned into a civil disturbance in Detroit, Michigan. It began in the early morning hours of Sunday July 23, 1967. The precipitating event was a police raid of an unlicensed, after-hours bar then known as a blind pig, just north of the corner of 12th Street (today Rosa Parks Boulevard) and Virginia Park Avenue, on the city's Near West Side. Police confrontations with patrons and observers on the street evolved into one of the deadliest and most destructive riots in the history of the United States, lasting five days and surpassing the violence and property destruction of Detroit's 1943 race riot just 24 years earlier.

Ex Output:
what started the riot in detroit in 1967

Ex Input:
The Galilean moons are the four largest moons of Jupiter -- Io, Europa, Ganymede, and Callisto. They were first seen by Galileo Galilei in January 1610, and recognized by him as satellites of Jupiter in March 1610. They are the first objects found to orbit another planet. Their names derive from the lovers of Zeus. They are among the largest objects in the Solar System with the exception of the Sun and the eight planets, with a radius larger than any of the dwarf planets. Ganymede is the largest moon in the Solar System, and is even bigger than the planet Mercury. The three inner moons -- Io, Europa, and Ganymede -- are in a 4: 2: 1 orbital resonance with each other. Because of their much smaller size, and therefore weaker self-gravitation, all of Jupiter's remaining moons have irregular forms rather than a spherical shape.

Ex Output:
