Passage Two
Can animals be made to work for us Some scientists think that one day animals may be trained to do a number of simple jobs that are now done by human beings. They point out that at a circus, for example, we may see elephants, monkeys, dogs and other animals doing quite skillful things. Perhaps you have seen them on the television or in a film. If you watch closely, you may notice that the trainer always gives the animal a piece of candy or a piece of fruit as a reward. The scientists say that many different animals may be trained to do a number of simple jobs if they know they will get a reward for doing them. Of course, as we know, dogs can be used to guard a house, and soldiers in both old and modem times have used geese to give warning by making a lot of noise when a stranger or an enemy comes near. But it may be possible to train animals to work in factories. In Russia, for example, pigeons which are birds with good eyesight, are being used to watch

Passage Five Many animals are used to help scientists find cures for diseases. One of the most common animals used is monkeys, or primates. There are groups of people who want to stop the research on animals. They are called animal rights activists. The scientists say their research could help save the lives of many men, women and children. They try to cure diseases like cancer and AIDS. The animal rights activists say the animals suffer. They take baby monkeys away from their mothers, and sometimes holes are drilled in their heads. The activists have tried to stop the research for the past 10 years. They let animals go free or damage the labs. The University of California at Davis has 3,800 rhesus macaque monkeys. It is one of the largest primate research labs. The activists sent letters to researchers at Davis and about eighty other researchers around the country, whose names were on the web pages. The warning letters had razor blades hidden so that a person could slice
