Input: Consider Input: story: Czechoslovakia or Czecho-Slovakia (; Czech and , "Česko-Slovensko") was a sovereign state in Central Europe that existed from October 1918, when it declared its independence from the Austro-Hungarian Empire, until its peaceful dissolution into the Czech Republic and Slovakia on 1 January 1993. 

From 1939 to 1945, following its forced division and partial incorporation into Nazi Germany, the state did not "de facto" exist but its government-in-exile continued to operate. 

From 1948 to 1990, Czechoslovakia was part of the Soviet bloc with a command economy. Its economic status was formalized in membership of Comecon from 1949, and its defense status in the Warsaw Pact of May 1955. A period of political liberalization in 1968, known as the Prague Spring, was forcibly ended when the Soviet Union, assisted by several other Warsaw Pact countries, invaded. In 1989, as Marxist–Leninist governments and communism were ending all over Europe, Czechoslovaks peacefully deposed their government in the Velvet Revolution; state price controls were removed after a period of preparation. In 1993, Czechoslovakia split into the two sovereign states of the Czech Republic and Slovakia. 



The country was of generally irregular terrain. The western area was part of the north-central European uplands. The eastern region was composed of the northern reaches of the Carpathian Mountains and lands of the Danube River basin., question: What kind of economy did they have from 48-90

Output: a command economy.

Input: Consider Input: story: CHAPTER XXX 

FERN Mullins rushed into the house on a Saturday morning early in September and shrieked at Carol, "School starts next Tuesday. I've got to have one more spree before I'm arrested. Let's get up a picnic down the lake for this afternoon. Won't you come, Mrs. Kennicott, and the doctor? Cy Bogart wants to go--he's a brat but he's lively." 

"I don't think the doctor can go," sedately. "He said something about having to make a country call this afternoon. But I'd love to." 

"That's dandy! Who can we get?" 

"Mrs. Dyer might be chaperon. She's been so nice. And maybe Dave, if he could get away from the store." 

"How about Erik Valborg? I think he's got lots more style than these town boys. You like him all right, don't you?" 

So the picnic of Carol, Fern, Erik, Cy Bogart, and the Dyers was not only moral but inevitable. 

They drove to the birch grove on the south shore of Lake Minniemashie. Dave Dyer was his most clownish self. He yelped, jigged, wore Carol's hat, dropped an ant down Fern's back, and when they went swimming (the women modestly changing in the car with the side curtains up, the men undressing behind the bushes, constantly repeating, "Gee, hope we don't run into poison ivy"), Dave splashed water on them and dived to clutch his wife's ankle. He infected the others. Erik gave an imitation of the Greek dancers he had seen in vaudeville, and when they sat down to picnic supper spread on a lap-robe on the grass, Cy climbed a tree to throw acorns at them. , question: What was said about Erik?


Output: he's got lots more style than town boys
