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.

Pizza has a long history. The ancient Greeks first had the idea of putting vegetables on large flat pieces of bread, and ‘pizza ovens’ have been found in the ruins of Roman cities. But for centuries one vital ingredient was missing - the first tomatoes were not brought to Europe until the sixteenth century, from South America. It was the nineteenth century before Rafaele Esposito, a baker from Naples, began to sell the first modern pizzas. He was asked to bake a special pizza for a visit by the Italian King and Queen in 1889, and so the first pizza Margarita was created, named after the Queen. Pizza became a favourite dish in Italy, but it was after the Second World War, when thousands of American soldiers went home from Europe, that pizza really became an international dish. Soon there were pizzerias all over the USA, and American chains like Pizza Hut spread the idea around the world. Today the average American eats over ten kilogrammes of pizza a year, and the world's largest pizza (measuring thirty metres across) was baked not in Italy, but in Havana, Cuba! 1 Where were the first pizzas made?
