Input: Read this: As this process continued, the missile found itself being used for more and more of the roles formerly filled by guns. First to go were the large weapons, replaced by equally large missile systems of much higher performance. Smaller missiles soon followed, eventually becoming small enough to be mounted on armored cars and tank chassis. These started replacing, or at least supplanting, similar gun-based SPAAG systems in the 1960s, and by the 1990s had replaced almost all such systems in modern armies. Man-portable missiles, MANPADs as they are known today, were introduced in the 1960s and have supplanted or even replaced even the smallest guns in most advanced armies.
Question: Small missiles were designed that could be mounted on what?

Output: armored cars and tank chassis

QUES: Detroit, like many places in the United States, developed racial conflict and discrimination in the 20th century following rapid demographic changes as hundreds of thousands of new workers were attracted to the industrial city; in a short period it became the 4th-largest city in the nation. The Great Migration brought rural blacks from the South; they were outnumbered by southern whites who also migrated to the city. Immigration brought southern and eastern Europeans of Catholic and Jewish faith; these new groups competed with native-born whites for jobs and housing in the booming city. Detroit was one of the major Midwest cities that was a site for the dramatic urban revival of the Ku Klux Klan beginning in 1915. "By the 1920s the city had become a stronghold of the KKK," whose members opposed Catholic and Jewish immigrants, as well as black Americans. The Black Legion, a secret vigilante group, was active in the Detroit area in the 1930s, when one-third of its estimated 20,000 to 30,000 members in Michigan were based in the city. It was defeated after numerous prosecutions following the kidnapping and murder in 1936 of Charles Poole, a Catholic Works Progress Administration organizer. A total of 49 men of the Black Legion were convicted of numerous crimes, with many sentenced to life in prison for murder.
By which decade had the KKK become very active in Detroit?

ANS: 1920s


A few centuries later, coinciding with the first waves of the invading Germanic peoples (Suevi, Vandals and Alans, and later the Visigoths) and the power vacuum left by the demise of the Roman imperial administration, the church assumed the reins of power in the city and replaced the old Roman temples with religious buildings. With the Byzantine invasion of the southwestern Iberian peninsula in 554 the city acquired strategic importance. After the expulsion of the Byzantines in 625, Visigothic military contingents were posted there and the ancient Roman amphitheatre was fortified. Little is known of its history for nearly a hundred years; although this period is only scarcely documented by archeology, excavations suggest that there was little development of the city. During Visigothic times Valencia was an episcopal See of the Catholic Church, albeit a suffragan diocese subordinate to the archdiocese of Toledo, comprising the ancient Roman province of Carthaginensis in Hispania.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who took power in Valencia after the Roman administration was gone?
Ah, so.. the church

Input: Read this: During World War II, the palace was bombed nine times, the most serious and publicised of which resulted in the destruction of the palace chapel in 1940. Coverage of this event was played in cinemas all over the UK to show the common suffering of rich and poor. One bomb fell in the palace quadrangle while King George VI and Queen Elizabeth were in residence, and many windows were blown in and the chapel destroyed. War-time coverage of such incidents was severely restricted, however. The King and Queen were filmed inspecting their bombed home, the smiling Queen, as always, immaculately dressed in a hat and matching coat seemingly unbothered by the damage around her. It was at this time the Queen famously declared: "I'm glad we have been bombed. Now I can look the East End in the face". The royal family were seen as sharing their subjects' hardship, as The Sunday Graphic reported:
