Task 1.  Read the text and circle the correct answer  

Nauryz

The most important Kazakh holiday of the year is "Nauryz" - the Kazakh New Year. People celebrate it on March 22. Families gather together. They help each other in constructing a "yurt" which is a traditional Kazakh home. As a guest you will sit at a long low table and eat such Kazakh dishes as "karta" (round pieces of dried horse meat), "plov", "baursak", "besbarmak" .

The main traditional meal of this holiday is "Nauryz Kozhe". It is made of 7 components: meat, water, salt, airan, wheat, rice and raisin. Nauryz Kozhe is cooked by a family or a group of families or the people of the whole aul, village or settlement. All grown-ups and children must eat Kozhe or at least taste it. In fact this kind of Kozhe is a wish, a hope for the New Year to be successful.

At the end of the meal you will sit and have tea and listen to musicians playing dombyras and kobyz and singing songs. One of the major features of "Nauryz” is the traditional costumes that men and women wear. This holiday is very popular like many other holidays you celebrate in spring.
