3.Read and answer the questions I live in Leeds, in the north of England. Last month, I went to London. I stayed for two nights. I arrived on Monday afternoon and left on Wednesday afternoon. I stayed in a hotel near to the Tower of London. I went by train. It was fast and very convenient. I visited the Tower. I saw the Crown Jewels. I also saw the place where famous people, including a queen of England, Anne Boleyn, were beheaded. I had a trip to the British Museum. I wanted to see the Elgin marbles. The Elgin marbles are Greek sculptures. They were at the Parthenon in Athens, the capital of Greece, but a British man, Lord Elgin, brought them to Britain in 1816. Sadly, when I arrived, the Elgin Marble rooms were closed! Disappointing, but there was plenty other stuff to see. On Tuesday evening, I went to a show. It was 'The Windsors' - a comedy about the royal family. I didn't think it was funny, so I left at the interval. I ate at Brasserie Cote on Monday night and then on Tuesday night, I had fish and chips. I sat beside Tower Bridge and ate them while watching the world go by. The weather was fine, so I had a long walk along the Thames and I saw some famous sites. There are many Roman remains in London. The old sits comfortably next to the new and modern. Everyone was very friendly. I had a great stay and I would like to return soon. By Lou. 1. Who brought the Marbles to Britain? 2. When did he bring them? 3. What show did Lou go and see? 4. Why did she leave at the interval? 5. What did she have to eat on Tuesday night? 6. What was the weather like? 7. Where did she go walking? 8. How did she find the people? 9. How do the old and the new sit together in London? 10. Does Lou want to return?​ дам 60 балів
