Rather than investing in expensive scientific equipment to predict earthquakes, perhaps scientists should spend more time watching their pets. Many scientists now believe that the behaviour of certain animals could help them to predict certain natural disasters. For example, Chinese scientists in the 1970s thought that reports of farm animals running round in circles might indicate an impending disaster. They decided to evacuate the city of Haichin, which shortly afterwards was hit by a huge earthquake. Thousands of lives were probably saved as a result. Japanese scientists have also discovered that catfish become livelier several days before moderately strong earthquakes. Many scientists now accept that this can't be pure coincidence; they believe that the explanation may be linked to slight changes in the Earth's magnetic field. Although human beings can't perceive such changes, it is thought that the sensitive nervous systems of some animals must be affected by them. Now scientists must discover exactly which animals are affected in this way, so that more lives can be saved in the future. 1 What is the article about? Answer A.
