Question: Article: In October on the east coast of Australia migrating humpback whales pass very close to the shore. With the help of Max Egan, we went to film them near Byron Bay. It was extremely exciting to spot the little puffs of spray on the horizon. When migrating, the whales can be traveling at speeds of about 12km/h and can dive under anywhere between five and forty minutes, but with many years of experience Max usually guided our boat to exactly the right place to provide us with amazing sighting. As the whales break the surface like submarines , the water spills off their broad dark backs and huge tails. Then, with a powerful down stroke, they dive back into the depths of the sea, leaving just a smooth glassy patch of water or "footprint" on the surface to show where they had been. One day we had traveled up and down the shore and far out to the sea in search of whales, but the horizon was deserted. There was no report of whales in the area so we decided to test out Max's new, highly sensitive hydrophone and the result was astonishing. As soon as the hydrophone was in the water, we found ourselves listening to the most beautiful voices. What may have seemed like a vast empty ocean was filled with the singing of whales. It is the males which sing, as they migrate between feeding and breeding grounds. No one knows for sure what the purpose of these songs is, whether they are love songs to the females or warnings to other males to stay away. It was thought that each population of humpbacks had its own song which remained regular but recent findings suggest that the whales appreciate a memorable tune and quickly adopt any new songs they hear.
Answer: The songs of whales.

Answer: Which finding about whales is beyond the writer's expectation?

Question: Article: What's your dream vacation? Watching wildlife in Kenya? Boating down the Amazon? Sunbathing in Malaysia? New chances are opening up all the time to explore the world. So we visit travel agents, compare packages and prices, and pay our money. We know what our vacation costs us. But do we know what it might cost someone else? It's true that many poorer countries now depend on tourism for foreign income. Unfortunately, though, tourism often harms the local people more than it helps them. It might cost their homes and lands. In Myanmar, 5,200 people were forced to leave their homes among the pagodas in Bagan so that tourists could visit the pagodas. Tourism might also cost the local people their livelihood and dignity. Local workers often find only menial jobs in the tourist industry. And most of the profits do not help the local economy. Instead, profits return to the tour operators in wealthier countries, When the Maasai people in Tanzania were driven from their lands, some moved to city slums. Others now make a little money selling souvenirs or posing for photos. Problems like these were observed more than 20 years ago. But now some non-government organizations, tour operators and local governments are working together to begin correcting them. Tourists, too, are putting on the pressure. The result is responsible tourism, or "ethical tourism." Ethical tourism has people at its heart. New international agreements and codes of conduct can help protect the people's lands, homes, economies and cultures. The beginnings are small, though, and the problems are complex. But take heart. The good news is that everyone, including us, can play a part to help the local people in the places we visit. Tour operators and companies can help by making sure that local people work in good conditions and earn reasonable wages. They can make it a point to use only locally owned hotel, restaurants and guide services. They can share profits fairly to help the local economy. And they can involve the local people in planning and managing tourism. What can tourists do? First, we can ask tour companies to provide information about the conditions of local citizens. We can then make our choices and tell them why. And while we're abroad, we can: Buy local foods and products, not imported ones. Pay a fair price for goods and services and not bargain for the cheapest price. Avoid flaunting wealth. Ask before taking photographs of people. They are not just part of the landscape! Let's enjoy our vacation and make sure others do, too.
