They show a strong interest in the bones of their own kind.They are often seen gently touching the bones with their trunks and feet while remaining very quiet.Sometimes elephants completely unrelated to the dead will still visit their graves. Elephant researcher Meredith recalls something in his book about a typical elephant death ritual.The entire family of a dead elephant,including her young baby,were all gently touching her body with their trunks,trying to lift her. The elephant herd were all rumbling :The baby elephant was even observed to be weeping and made sounds that sounded like a scream,but then the entire herd fell incredibly silent.Then they began to throw leaves and dirt over the body and broke off tree branches to cover her.They spent the next two days quietly standing over her body.They sometimes had to leave to get water or food,but they would always return. Events of elephants behaving this way around human beings are common throughout Africa. On many occasions,they have buried dead or sleeping humans or helped them when they are hurt. An old woman fell asleep under a tree.When she woke up,there was an elephant standing over her,gently touching her.She kept very still because she was frightened.As other elephants arrived,they began to scream loudly and buried her under branches.She was found the next morning by the local people,unharmed. George Adamson also recalls when he shot all elephant from a herd that kept breaking into the farmers'gardens.George gave the:elephant's meat to 1ocal men and then dragged the rest of the body miles away.That night,the other elephants found the body,took the leg bones,returned them to the exact spot the elephant was killed,and made the death ritual.

Read the article and select the best answer. Article: The Future of Technology William, a businessman, arrives in a foreign airport. He doesn't show his passport. Instead, a machine in the wall reads the computer chip in his arm. This contains information about him: his name, age, and I.D number. He exits the airport, and a car door opens when it "sees" him. The car takes him to his hotel. His room "knows" he has entered the building and it "reads" his body. He is cold, so the room becomes warmer. William then watches a business presentation on a video wall. When he takes a bath, the presentation "follows him and continues on the bathroom wall. Finally, the room plays music to help him sleep. It turns off the music when it "sees" him sleeping. William doesn't exist, and none of this is real. But it might be soon. "In five to ten years, computing and communications are going to be free and everywhere, in your walls, in your car, on your body,' says Victor Zue, leader of Project Oxygen. Project Oxygen has one big idea: to create better relationships between machines and people. The dream is that computer will learn to understand what people want. So, what changes will there be at work? Firstly, the building will know where everyone is, all the time. You want to talk to someone? Type the person's name on the nearest computer. It will show you a map of the building and exactly where this person is. You then call this person, who picks up the nearest telephone, also shown on the computer. If he or she is busy with a client or in a meeting, the computer will tell you. Is all this really possible? Visit the Siebel Center, Illinois and see for yourself: computers in the doors and walls, cameras everywhere, the technology of the future, but here today. Question: William doesn't' show his passport because _ . Options: A: he is not required to show his passport B: he doesn't need a passport in that airport C: his information can be read by a machine D: only a man from foreign country needs to show his passport
