Составьте краткий пересказ текста (Sammary):
Congratulations, Roy!" said Elmer heartily. "You missed only one question. I announce you as the winner of this World Airways Contest!"

The audience applauded.

"You know that the prize is a trip, all expenses paid, to any place in the world. We are all interested to hear your choice. You can go anywhere you like between the North and South Poles!"

I had made my plans long ago. However, my voice trembled when I answered.

"I want to go to the Inner Station."

Elmer looked puzzled and surprised. It was clear that he didn't know what to say. Then he decided to make a joke of it.

"Ha, ha, very amusing, Roy! But the prize is a trip to any place on earth. You must stick to the rules, you know!"

He was laughing at me and that made me angry.

"I've read the rules very carefully," I said. "And they don't say 'on earth'. They say, 'to any partof the earth'. There's a big difference."

Elmer's smile disappeared. He looked anxiously at the TV cameras.

"Go on," he said. I cleared my throat.

"In 2054," I continued, "the United States signed a Convention which decided how far into space any planet's rights extended. Under that Convention, the Inner Station is part of earth, because it is inside the thousand kilometer limit."

The audience was on my side. Elmer made a few attempts to make me change my mind, but finally he gave up and said with a laugh:

"Well, you're a very determined young man, and you've won the prize after all. I hope they'll let you go."

Mom and Pop were pretty mad about the whole business, but it was too late for them to stop me. The only one who understood me was Uncle Jim (that's Pop's brother). He was counsellor for a big atomic energy combine, and he'd been to Mars two or three times, to Venus once, and to the moon so often he could not count the times.

I had wanted to go out into space ever since I was five. I was sixteen now, and rather big for my age. I had read everything I could find about aviation and astronautics. I had seen all the movies and telecasts from space. I had made models of famous spaceships. In my room I had hundreds of photographs not only of most of the famous ships, but all the important places on the planets as well.
