Question: Article: Most people think of a camel as an obedient beast of burden, because it is best known for its ability to carry heavy loads across vast stretches of desert without requiring water. In reality, the camel is considerably more than just the Arabian equivalent of mule . It also possesses a great amount of intelligence and sensitivity. The Arabs say that camels are so acutely aware of injustice and ill-treatment that a camel owner who punishes one of the beasts too hard finds it difficult to escape the camel's revenge .Apparently, the animal will remember an injury and wait for an opportunity to get revenge. In order to protect themselves from the vengeful beasts, Arabian camel drivers have learned to trick their camels into believing they have achieved revenge. When an Arab realizes that he has excited a camel's rage, he places his own garments on the ground in the animal's path. He arranges the clothing so that it appears to cover a man's body. When the camel recognizes its master's clothing on the ground, it seizes the pile with its teeth, shakes the garments angrily and steps on them in a rage again and again. In the end, after its rage has died away, the camel leaves, believing its revenge is completed. Only then does the owner of the garments comes out of hiding, safe for the time being, thanks to this clever trick.
Answer: camels try to punish people who ill-treated them

Question: Article: Great white sharks! Just hearing that name _ . In reality, these big fish have more to fear from us than we do from them. For many years, people killed countless great white sharks in the waters around the United States. But thanks to conservation efforts, great whites are making a comeback in the U.S. Two recent studies show that the population of these sharks is rising along the east and west coast. Why is the growing population of a killer fish something to celebrate? "When you fish too many of them, you start to lose balance in the environment," says shark researcher Tobey Curtis. As the biggest killer, sharks help keep the populations of fish, seals, and other creatures they eat from growing too large. In spite of their importance, great white sharks had long been hunted for their meat and their fins . Then, in 1997, the U.S. government passed a law that didn't allow the hunting of great whites. Afterwards, the numbers of these sharks in the U.S. waters started to increase. The law wasn't the only thing that has helped great whites. Conservationists have also played a part in the sharks' comeback. The research group OCEARCH is using a method called tagging to help change people's attitudes about great white. They let the public follow each shark as it travels the world's oceans. OCEARCH also gives each tagged shark a name to help people form a closer connection with the big fish. The group's most well-known shark is named Katharine. She was tagged last year near Cape Cod, Massachusetts. Since then, thousands of people have tracked Katharine's movements on Twitter and the OCEARCH website. This helps people see sharks in a new way. Chris Fischer, the founder of OCEARCH believes learning to appreciate great whites will encourage people to do more to protect them.
