Поставьте все части текста в нужной логической последовательности.

A.This modern festival started in California in the United States in 1960s because some black people wanted to celebrate their original history and culture in their new country. Some Africans in the USA, especially those living in white areas, want their children to value their African-American history. Kwanzaa is not a religious festivals, but a festival that celebrates several important ideas and principles like unity, cooperation and creativity, for example.

B.As Kwanzaa becomes popular, it is also becoming more commercialized. There are now Kwanzaa cards, books on Kwanzaa, poetry and recipes. Parents are buying more expensive gifts for their children. Now there is also ‘ Nia umoja’ a kind old man, rather like Father Christmas, who attracts children to the festival. Kwanzaa is an interesting balance of African and modern American influence.

C.Kwanzaa is a modern festival celebrated by African Americans. It comes from traditional African agricultural festivals. In fact, the name ‘Kwanzaa’ comes from the Swahili word for the first fruit. African Americans also use a Swahil greeting, ‘What’s new?’ during their festival of Kwanzaa.

D.The festival lasts for seven days, from December 26. People light candles, give gifts, and talk about one special principle every day, on each day, on each night there is a dance, and on the final night there is a big feast.
