Read the article and select the best answer. Article: Let's say a person gets up at 7:00 in the morning and goes to bed at 11:00 at night. He comes home from work about 6:30, and by the time he has finished with dinner it is after 8:00. He steps outside in the summer to relax -- but it's already getting dark! Not much time to enjoy the summer day. Now suppose you set the clock ahead one hour. This person still does everything at the same time -- but this time, when he steps out at 8:00 there's still plenty of light to enjoy. An hour of daylight has been "saved" for him! Daylight saving time doesn't, of course, add any hours to a day. This is impossible. All it does is to increase the number of useful hours of daylight during the seasons when the sun rises early. Daylight saving is most popular in cities. It allows the closing of offices, shops, and factories at the end of the working day while the sun is still high. Farmers, who do their work by sun time, usually do not observe daylight saving time. They cannot work in the field before the morning dew has dried or after it appears in the evening. Did you know who first thought of daylight saving time? It was Benjamin Franklin! When he was living in France in the 18th century, he suggested the idea to the people in Paris. But it was not adopted then. Daylight saving laws were first passed during World WarI, when materials for making electricity was hard to find, and when it was necessary to save on _ light. With daylight saving, the bedtime of many people comes soon after it gets dark, while without it, if people stay up until the same hour they may have to use artificial light. Germany was the first country to adopt daylight saving time in 1915. Then England used it in 1916, and the United States adopted it in 1918.
