Read the following article and answer the question. Article: Dolphins are interesting animals and researchers find them interesting to watch. They don't have hands, but can use tools to solve problems, just like us. Scientists have observed a dolphin trying to get a shy eel to come out of its hole by poking it with a dead fish. Many species of dolphin live in large societies. They have many different relationships and need a good communication system; they use a variety of sounds to communicate with each other. There is currently no evidence that dolphins have a language of their own. But scientists still have a lot to find out about these animals and so there are certain to be a few surprises in the future. At Kewalo Basin Marine Laboratory in Hawaii, the dolphin team have developed a sign langue to communicate with the dolphins, and the results are amazing. Not only do the dolphins understand the meaning of individual words, they also understand the significance of word order in a sentence. For example, when they were asked to 'touch the ball with your tail and then jump over it' they generally responded correctly and straight away, which showed that they understood the langue. Most mammals seem to enjoy play--but dolphins seems to like making their games as challenging as possible. On a beautiful day in 1997, researchers working at a beach, off the southern coast of Brazil, observed a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins approached the dog and then started throwing it into the air. The dog seemed to enjoy the 'game' and continued playing with the dolphins for more than an hour. From then on, different dogs were seem trying to interact with the dolphins. Dolphins live in a very different world to ourselves, but they are very good at our 'intelligence tests'. For example, they will jump out of the water when they hear a whistle noise. They do this because they will get a fish as a reward. There is still much to learn about these flexible problem-solvers, but from the evidence so far, it would seem as though... Question: Dolphins will jump out of the water when they hear a whistle noise in order to _ . Answer:

- watch people

Read the following article and answer the question. Article: LONDON (Reuters)--New faces given to a Chinese man after a bear tore off part of his face and a FrenchCaribbean man disfigured by a rare tumor show that such transplants can work and are not medical oddities ,researchers said.

In 2006,Chinese doctors performed a face transplant on a 30yearold hit by a bear.While there were some complications with tissue rejection following the operation,two years later the man was doing well,his doctors said."This case suggests that facial transplantation might be an option for _ a severely disfigured face,and could enable patients to bring themselves back into society," Shuzhong Guo and colleagues at Xijing Hospital in China wrote.

Read the following article and answer the question. Article: At least once a month one of my little kind kids and I try to have a father and daughter date night. Last night we were out for diner together after doing some fun things. We talked about some of her kind activities she did at school for their 100 Acts of Kindness challenge her class had. It was great to listen to the little things she and her classmates did to spread kindness. Many times on our date night we try to do an act of our own, as she is often my sidekick on our kindness adventures. My later smile card is one about anonymously buying a stranger's meal so I asked Rachel if we should find someone in the restaurant and buy their dinner. She loved the idea so we chose an older couple sitting behind us. I had a few Smile Cards on me (as always!) so we separately told our server our plan. He was new and wasn't sure how to do it but said he would go and find out. When he dropped off the checks, she smiled at us and told us he would give them the Smile Cards and that the world needed more people like us. Rachel got the biggest smile on her face when he said that to her and I love that he helped remind her that kindness matters. My daughter normally likes to stay and watch the reactions of our kindness "victims" but we had to get going. When we got home she was so excited to tell her Mom about what we did. My wife told Rachel how nice that was and how it would spread many smiles with the server, his manager, the couple and anyone else they told about the experience. We love any ripple of kindness we can send out into the world and I'm sure we made the couple smile with that one last night! Question: What's the main idea of the passage? Answer:
