Article: There's a big zoo in our city. It's about five kilometres away from my house. I like all kinds of animals. I often go to the zoo by bus on Sundays. In the zoo, I can see many different kinds of animals, such as monkeys, bears, pandas, tigers, lions and dolphins. Some animals are friendly, but some are not. Tigers, lions and bears are dangerous, so they have to stay in cages. But I don't think it's good for animals to stay in cages. They are not happy. They should be free. Tigers and lions usually live in forests. They can run very fast there. They catch and eat small animals like deer and rabbits. But now in the zoo, they live in small rooms. They walk round and round in the cages, and they want to get out. I feel sorry for them. Of all the animals I like dolphins best. The most interesting animals in the zoo that I like are dolphins. I like watching them swim and jump. They swim fast and they jump very high. They are very clever. They can play with balls. They are very friendly to people. If you fall into the water and can't swim, they may come to help you. Question: I like dolphins best because _ . Yes or no, is the answer "they are interesting, clever and friendly"?
No
