input question: Write a multi-choice question for the following article, with the given choices and answer: Article: It's the end of class. When the bell rings, students of Luohu Foreign Languages School in Shenzhen quickly take out their cell-phones. They want to log on to their microblogs to check the funny things that have happened in the last hour. Since last year, the trend of microblogging has swept the country. Recent surveys show that most students in middle schools have a microblog, and some even update their blogs over five times per day. "We learn many fresh and interesting things on microblogs and they have become popular topics in class," said Liang Jianmin, 14, a student at Harbin No 3 Middle School.

Instead, it can become a window for parents to understand their children. "If parents can read their children's microblogs, they'll know their thoughts, thus leading to better communication and solutions to problems," he said. Micro blogging tips for kids 1.
