By nineteen-oh-seven, they opened a movie theater in New Castle, Pennsylvania. Within ten years, the Warner brothers started producing movies, and moved that part of the business to California. In nineteen eighteen, their first complete picture was called "My Four Years in Germany." The film was based on a book by the United States' ambassador to the court of Kaiser Wilhelm. In nineteen twenty-five, they began to work to include the technology for sound in their movies. Two years later, Warner Brothers Pictures released the first major movie with sound, or "talking picture." It was called "The Jazz Singer" and it was a huge success. In the nineteen thirties, the company made several films that were highly praised, including "Little Caesar," "The Public Enemy", "The Gold Diggers" and "Forty-Second Street." The Warner Brothers' success continued in the nineteen forties with movies like "The Maltese Falcon," and "Casablanca."

There is not enough oil in the world now. As time goes by, it becomes less and less, so what are we going to do when it runs out? Perhaps we will go back to using horses, carriages and bicycles. In the Second World War, some people didn't use gas made from petroleum  in their cars. They made gas from wood and plants instead. The car didn't go fast, but they ran, so this was better than nothing. However, in the future, we can't cut down all our trees to make gas; we need our trees for other things, too. Besides different types of gas, we can also use electricity  to run our cars, but first we must make the electricity! Some countries have coal  and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers, and they can use the power of water to turn turbines  and make electricity more easily and cheaply. We are also able to get power from the ocean tides. We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again. Which of these ways will be used to run our cars in the future? How many ways are suggested to make electricity in the passage? A) 2. B) 5. C) 4. D) 3.
