Ques:Article: About one million years ago, the Ice Age began. The Ice Age was a long period of time in which four great glaciers pushed southward to cover almost all the upper half of North America, and then melted away. Each glacier was a thick sheet of ice and snow that spread out from a center near what is now Hudson Bay in Canada. The winters were long, and the cool summers were too short to melt much of the ice and snow. The ever-growing sheet built up to a thickness of two miles at its center. As all glaciers do, these great glaciers slid. They pushed down giant trees in their paths and scraped the earth bare of soil. Many animals moved farther south to escape. Others stayed and were destroyed. When winters of little snow came, the summer cut into the edges of the ice sheets. As the glaciers melted, rocks soil and other things that had mixed with the ice and snow were left. New hills, lakes and rivers were formed. The last of the great glaciers began its melting about 11, 000 years ago. Its melting formed the Great Lakes. These lakes today are little changed from their early sizes and shapes. The largest of the North American river systems was also influenced by the glaciers. This is the Mississippi-Missouri-Ohio system. These rivers were miles wide at first. Through the years they settled into _ present channels. Question: The main idea of this passage is _ . Yes or no, is the answer "how glaciers changed North America"?

Ques:Article: Your teenage daughter is supposed to be doing homework, but you catch her chatting online. She tells you that she's talking about the math test tomorrow. Before your eyes start rolling, listen up: teens are using social networking sites for more than just gossip, according to a new study by the National School Boards Association. The students who took part in the online survey, aged 9 to 17, said they spent almost as much time on social networking online as they did watching television. And it is what these kids are talking about online that is causing such a cheer: education. Of the students who took part in the study 60 percent reported that some of the most popular social networking topics were college planning, learning outside of school, careers, and schoolwork. They also reported posting writing and art projects that might have nothing to do with schoolwork. Ann Flynn, director of education technology for the National School Boards Association, says social networking tools into educational is the way forward. Flynn says a school in Cleveland, Ohio is posting students' book reports on a blog for students of their own ages, parents and other teachers to read and comment on. "If someone reacts other than the teacher, a child is much more likely to take an assignment seriously," Flynn says. Not only students but also parents can benefit. Now parents can go online and know what the class is doing. So, next time your child says her blog is educational, get curious, sit down and check out the blog with her. You might just learn something new yourself. Question: How does the school in Cleveland mentioned in the text use social net-working sites? Yes or no, is the answer "It welcomes comments on students' book reports online."?

Ans:Yes
