Problem: Due to the 1973 spike in oil prices, the economy of Iran was flooded with foreign currency, which caused inflation. By 1974, the economy of Iran was experiencing double digit inflation, and despite many large projects to modernize the country, corruption was rampant and caused large amounts of waste. By 1975 and 1976, an economic recession led to increased unemployment, especially among millions of youth who had migrated to the cities of Iran looking for construction jobs during the boom years of the early 1970s. By the late 1970s, many of these people opposed the Shah's regime and began to organize and join the protests against it.
Why did millions of youth migrate to the urban areas of Iran in the mid 1970s?
The answer is the following: construction jobs

Problem: In the 16th century political and religious changes altered the attitude of historians towards John. Tudor historians were generally favourably inclined towards the king, focusing on John's opposition to the Papacy and his promotion of the special rights and prerogatives of a king. Revisionist histories written by John Foxe, William Tyndale and Robert Barnes portrayed John as an early Protestant hero, and John Foxe included the king in his Book of Martyrs. John Speed's Historie of Great Britaine in 1632 praised John's "great renown" as a king; he blamed the bias of medieval chroniclers for the king's poor reputation.
Which historians were favourably inclined towards the king?
The answer is the following: Tudor historians

Problem: During the Miocene continents continued to drift toward their present positions. Of the modern geologic features, only the land bridge between South America and North America was absent, the subduction zone along the Pacific Ocean margin of South America caused the rise of the Andes and the southward extension of the Meso-American peninsula. India continued to collide with Asia. The Tethys Seaway continued to shrink and then disappeared as Africa collided with Eurasia in the Turkish-Arabian region between 19 and 12 Ma (ICS 2004). Subsequent uplift of mountains in the western Mediterranean region and a global fall in sea levels combined to cause a temporary drying up of the Mediterranean Sea resulting in the Messinian salinity crisis near the end of the Miocene.
Which crisis occured towards the end of the Miocene period?
The answer is the following: Messinian salinity crisis

Problem: In the year 743 the synod in Leptines (Leptines is located near Binche in Belgium) spoke out furiously against the excesses in the month of February. Also from the same period dates the phrase: "Whoever in February by a variety of less honorable acts tries to drive out winter is not a Christian, but a pagan." Confession books from around 800 contain more information about how people would dress as an animal or old woman during the festivities in January and February, even though this was a sin with no small penance. Also in Spain, San Isidoro de Sevilla is written complaint in the seventh century that people coming out into the streets disguised in many cases the opposite gender.
In what year did the synod in Leptines rant against the excesses of the festival?
The answer is the following:
743
