TRUE OR FALSE.
A rich American went to Paris and bought a picture by a modern artist. He had paid a lot of money for the picture, so he thought the picture was very good. He came to the hotel where he stayed and wanted to hang the picture. To his surprise he could not tell what was the top and what was the bottom. So he thought of a plan and invited the artist to dinner. The artist looked at the picture many times. He put on his glasses and approached the picture to look at it more closely. And at last when they began to drink coffee, the artist told the American that the picture was upside down. The American was surprised and wondered why the artist had not told it to him at once. The artist had to admit that he himself was not sure about it at first. So the rich American left the picture on the wall as it was. He thought that nobody noticed that it was upside down. 1) The text describes modern French art. 2) The person who bought the picture by a modern artist was from the USA. 3) The picture was a water colour portrait of the American`s wife. 4) The picture was rather cheap but nice. 5) The American invited the artist to dinner in order to find out what was the name of the picture. 6) The artist noticed at once that the picture was upside down. 7) The rich American turned the picture over so that nobody would notice that it was upside down.
