READING COMPREHENSION (0.5 pt)Read the passage below and choose the best answer for each question.One of the most important discoveries of the nineteenth century was a method of using natural gas forcooking and heating. Large amounts of natural gas are found in the United States, usually several thousandfeet below the surface of the earth. Natural gas is most often found in places where petroleum, the oil fromwhich gasoline is made, is found. Often the natural gas must be removed before the oil itself can be reached.For many years after natural gas was first discovered, it was thought to have no value. Finally, however,people began to understand its use and to find ways of storing it and moving it from place to place. Todaynatural gas is stored in large tanks and used for lighting, cooking and heating. It has also been used forelectric generators and hybrid cars recently. In many ways natural gas is one of our finest fuels. It can beused for cooking without making the room hot. It is cheap and can be moved easily from one place toanother through long pipelines, some of which are hundreds of miles in length.
