Прочитайте текст. Определите, какие из приведенных утверждений A5-A8 соответствуют содержанию текста (1 — True), какие не соответствуют (2 — False) и о чем в тексте не сказано, то есть на основании текста нельзя дать ни положительного, ни отрицательного ответа (3 — Not stated).
Every nation and country has a reputation of some kind. The Englishmen are believed to be cold, reserved, rather naughty, easy-going and fond of sport. They are the nation of stay-at- homes. «There is no place like home», they say. The English man’s home is his castle is a saying known all over the world.
They prefer a small house built for one family, with a small garden and a fire in the centre of the house. They like animals very much and follow many traditions especially concerning food and manners. We know much about English traditions and Customs but now I’d like to say a few words about the traditions of my native land-Russia.
First, some words about Russian people. To my mind, the main traits of their characters are their hospitality, their «open heartedness» and inventiveness. Russian fairytales reflect this. Our people are hardworking, patient, never loosing hope for better life. The Russians are the talented nation. Russia gave the world thousands of the world famous writers, composers, scientists, inventors and explorers. All of them are the pride of the nation.
Such names of Gzhel and Khokhloma are considered to be the symbols of Russia as well as matryoshkas and samovars. The history of Khokhloma goes back to the 17th century. The production of tableware-dishes, spoons, mugs was begun at that time in the villages of Suomino and Khokhloma in the Nizhniy Novgorod Province. Many carpenters, painters have been working since then reviving traditions of old masters.
The Khokhloma style is characterized by using plant elements in painting the tableware. The prevailing colors are black, yellow, golden, green and red.
Nowadays this craft is sure to be saved; it will be developed and brought into the future by the new generation of painters.

1) True 2) False 3) Not stated
