Переведите текст пожалуйста. Levi Strauss came to America from Germany. In the 1850 he arrived in San Francisco. San Francisco is a large city in the United Satesof America. It is situated in California. There were many people in California in those days because they wanted to find gold and become rich. They worked a lot looking for gold and spend much time in the water of the rivers. They needed strong trousers. Levi Strause had a lot of strong material. He hoped people could build tents with it. So he decided to make special trousers of this mateial. They were stong and people liked them. In one day Strause sold all the trousers he had. But they had no colour and became dirty very easily. So Strause decided to colour them blue. Now people all over the world wear blue jeans. They think they are good for work and travel, they are practical
