New technologies and a rising interest in healthier and organic eating have had a huge impact on how farms do business. At the same time, a growing population has put more demands on farmers. They need to find ways to increase their production levels. The small family farms that used to produce most of the products have been largely replaced by factory farms. Small family farms that are still operating are struggling to keep up. Technology has made most aspects of farm life easier than it has ever been before. Bigger and more efficient equipment makes work such as plowing up fields and sowing the seeds easier. Such tasks used to take two or three times as long. These advances have allowed farmers to work faster and more efficiently than ever before. In addition to newer technology, factory farms produce more products for less money than traditional farming would require. Modern farm life, despite the introduction of new technologies, has not changed much from what has always been. Farmers still wake up early, and spend their days doing hard work. There are animals to feed, cows to be milked, and fields to be plowed. Farm still requires a lot of hard work and sacrifice. The main change in modern farm life is still in the way farms are run. It is common for even small farms to have several hired workers and even an animal manager. Family-run farms are becoming rarer. Factory farms, with other larger farm corporations, are becoming the norm. Although there are still many traditional family farms, they are quickly dying as modern practices change farm life forever. 1.Factory farms now produce most of the products A.True B. False C. Not given 2.Farmers prefer to grow healthy and organic food. A.True B. False C. Not given

Once again I spelt out directions even a blind person could follow, I glanced impatiently at my watch, and waited. Only two hours remained until my flight left and it was an hour-and-a-half trip to the airport. Outside, heavy rains were pouring down. My house was so far north in the city that buses pass only three times a day. The telephone rang again. "Terribly sorry," began the man at the taxi company. Then I rea-lized that the taxi company, flooded with calls, could only offer in-city runs. I had heard this happens when the weather gets bad. I shouted into the phone that I had a plane to catch and I would meet the taxi outside my house. Standing in the wind-driven rain, I looked up and down the road. No taxi. A car went by, driver and passenger staring at the crazy foreigner in the downpour. Finally a white car appeared and pulled to a stop. A young man threw open the door, waving for me to get in. Shaking with cold and anger, I climbed in.
