Read the following article and select the best answer. Article: We live in a digital world now, and a student's technology needs have changed. For the early years, when you are in primary school, you can get by with no technology at all. Even if you have a computer, it's a good idea to get children familiar with libraries. At this age, trips to the library are like family outings. As you get closer to middle school, a computer with Internet access becomes more of a necessity. Teachers will often give assignments that require a student to use the Internet for research. After a computer, technology choices for students become more difficult to make - especially when it comes to cell-phones. Kids will beg their parents for a cell-phone, especially in middle school. For many parents, it's a safety issue: They want to know that their kids can reach them quickly if necessary. For teachers, cell phones can be used to record lessons when students are absent. But many teachers dislike cell-phones. Some kids send messages or have talks in the class. Sending messages also raises the problem of cheating on exams. More and more schools are now forbidding the use of cell-phones. Many kids see iPods as necessary things to have. IPods are great for music, but do they do anything good for your children's education? Maybe they do. s the opinion of Doug Johnson, an educator for 30 years. Johnson says that educators should accept all new forms of technology in the classroom, including iPods. "Some do more with their cell- phones than we can do with our laptops," he jokes. "I don't think we should be afraid. The truth is that it's easier to change the way we teach than to change the technology habits of an entire generation." Question: Why do parents agree to buy their children cell-phones? - They want their children to be cool. - They think cell-phones be helpful to their study. - They want to keep in touch with their children. - They want their children to keep up to date.
(Answer)
They want to keep in touch with their children.

Ques:Read the following 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. Question: What's the purpose of adopting daylight saving time? - To have more artificial light. - To have one more hour to work. - To make better use of daylight in certain seasons. - To have one more hour to rest.

Ans:
To make better use of daylight in certain seasons.
