question:
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: Who it did gain independence from?
answer:
Austro-Hungarian Empire

story: CHAPTER XXV 

PERILS OF THE FLOOD 

"Dave! Dave!" yelled Ben, as he saw our hero disappear into the swiftly-flowing river. "Look out, or you'll both be drowned!" 

"What's the trouble?" yelled Jerry Blutt, as he turned back for the first time since leaving the island. 

"Buster slipped in, and Dave went after him," answered Ben. "Oh, what shall we do?" he went on, despairingly. 

"Here--we'll throw out the rope!" answered the camp-worker, and took from his shoulder a rope he carried. 

In the meantime Dave had come up and was striking out with might and main for his chum. Our hero realized that Buster must be hurt, otherwise he would swim to save himself. 

"Must have struck on his head, when he went over," he thought, and he was right, poor Buster had done just that and now lay half-unconscious as the current swept him further and further from his friends. 

It was too dark to see much, and Dave had all he could do to keep in sight of the unfortunate one. But presently the stout youth's body struck against a rock and was held there, and our hero came up and seized the lad by the arm. 

"Buster! Buster!" he called out. "What's wrong? Can't you swim?" 

"Hel--help me!" gasped the fat youth. "I--I got a knock on the head. I'm so--so dizzy I do--don't know what I--I'm do--doing!" 

The current now tore Buster away from the rock, and he and Dave floated along on the bosom of the river for a distance of fifty yards. It was impossible to do much swimming in that madly-rushing element and Dave wisely steered for shore. He continued to support his friend, who seemed unable to do anything for himself. , question: what was Ben's concern?
answer:
they'll both drown


question:
story: I'm writing this letter slowly because I know you can't read fast. We don't live where we did when you left home. Your dad read in the newspaper that most accidents happened within 20 miles from our home, so we moved. 

I won't be able to send you the address because the last family that lived here took the house numbers when they moved so that they wouldn't have to change their address. This place is really nice. It even has a washing machine. I'm not sure it works so well though: last week I put a load in and pulled the chain and haven't seen them since. The weather isn't bad here. It only rained twice last week; the first time for three days and the second time for four days. About that coat you wanted me to send you, your uncle Stanley said it would be too heavy to send in the mail with the buttons on so we cut them off and put them in the pockets. 

John locked his keys in the car yesterday. We were really worried because it took him two hours to get me and your father out. Your sister had a baby this morning, but I haven't found out what _ is yet. The baby looks just like your brother. 

Uncle Ted fell in a whiskey vat last week. Some men tried to pull him out, but he fought them off playfully and drowned. We had him cremated and he burned for three days. 

Three of your friends went off a bridge in a pick-up trunk. Ralph was driving. He rolled down the window and swam to safety. You other two friends were in back. They drowned because they couldn't get the tail gate down. 

There isn't much more news at this time. Nothing much has happened. 

Love, 

Mom 

P.S. I was going to send you some money but the envelope was already sealed., question: who was in the car?
answer:

his mom and father
