Input: The story of the rise of politician Willie Stark from a rural county seat to the governor's mansion is depicted in the film. He goes into politics, railing against the corruptly run county government, but loses his race for county treasurer, in the face of unfair obstacles placed by the local machine. Stark teaches himself law, and as a lawyer, continues to fight the local establishment, championing the local people and gaining popularity. He eventually rises to become a candidate for governor, narrowly losing his first race, then winning on his second attempt. Along the way he loses his innocence and becomes as corrupt as the politicians he once fought against. When his son becomes paralyzed following a drunk driving accident that kills a female passenger, Stark's world starts to unravel and he discovers that not everyone can be bought off. The story has a complex series of relationships. All is seen through the eyes of the journalist, Jack Burden, who admires Stark and even when disillusioned still sticks by him. Stark's campaign assistant, Sadie is clearly in love with Stark and wants him to leave his wife, Lucy. Meanwhile, Stark philanders and gets involved with many women, taking Jack's own girlfriend, Anne Stanton, as his mistress. When Stark's reputation is brought into disrepute by Judge Stanton (Anne's uncle), he seeks to blacken the judge's name. When Jack finds evidence of the judge's possible wrongdoing, a quarter century earlier, he hides it from Stark. Anne gives the evidence to Stark, who uses it against her uncle, who immediately commits suicide. Anne seems to forgive Stark, but her brother, the surgeon who helped save Stark's son's life after the car crash, cannot. The doctor eventually assassinates Stark after Stark wins an impeachment investigation. The doctor in turn is shot down by Sugar Boy, Stark's fawning assistant. The main plot is a thinly disguised version of the rise of real-life 1930s Louisiana Governor, Huey Long, Long's efforts to blacken the name of Judge Benjamin Pavy, and Long's assassination by the Judge's son-in-law (compared to nephew, as in the film), Dr. Carl Weiss.

Now complete the following example -
Input: The Czech lands were among the first industrialized countries in continental Europe during the German Confederation era. The Czech industrial tradition dates back to the 19th century, when the Lands of the Bohemian Crown were the economic and industrial heartland of the Austrian Empire and later the Austrian side of Austria-Hungary. The Czech lands produced a majority  of all industrial goods in the Empire, some of which were almost monopolistic. The Czechoslovak crown was introduced in April 1919. Introduced at a 1:1 ratio to the Austro-Hungarian currency, it became one of the most stable currencies in Europe. The First Republic became one of the 10 most developed countries of the world . The consequences of the 1938 Munich Agreement and subsequent occupation were disastrous for the economy. After the occupation and forced subordination of the economy to German economic interests, the crown was officially pegged to the mark at a ratio of 1:10, even though the unofficial exchange rate was 1 to 6-7 and Germans immediately started buying Czech goods in large quantities. In accordance with Stalin's development policy of planned interdependence, all the economies of the socialist countries were tightly linked to that of the Soviet Union. Czechoslovakia was the most prosperous country in the Eastern Bloc, however it continued to lag further behind the rest of the developed world. With the disintegration of the communist economic alliance in 1991, Czech manufacturers lost their traditional markets among former communist countries in the east. Today, this heritage is both an asset and a liability. The Czech Republic has a well-educated population and a well-developed infrastructure. 
Question: Which happened first, the crown introduced to Czechslovakia or the crown set at an exchange rate at 1 to 10?
Output: 


Output: crown was introduced
