Article: There are many traditions around the holidays. "Holiday traditions" are things that people do every year during a holiday such as Christmas or Thanksgiving. At Christmas, for example, many people put up a Christmas tree or Christmas lights. These are Christmas traditions that have been going on for many years. But there is a "new" Christmas tradition that has become very popular: _ , a TV channel that shows nothing but a large log fire, blazing in a fireplace. People put it on their TV and it makes them feel like they are watching and listening to a crackling fire. It makes them feel calm and comfortable. The origin dates back to 1986 in Canada. At that time, not very many people knew about it or watched the channel. Today, more than three million people watch the firelog channel during the winter holiday season. That year, the firelog channel was created to give the workers in the company that is now called Shaw Cable, a break at Christmas. By running the firelog during the holidays, everyone could go home for a few days and enjoy a bit of time off. At that time, it was only broadcast to people in Edmonton but today it reaches people across Canada and beyond. This year, the Shaw firelog was updated. It is pretty high tech. Although it's still really just a fire log that has been filmed, it has its own Twitter account (@ShawFireLog), its own Facebook page and it even has a computer App so you can see the burning log on a smartphone or a tablet. The Shaw firelog will burn until Jan. 5 on Shaw Cable, channel 222.

Article: There are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. and some do one simple job. When an automatic washing machine is switched on, water pours in. The machine waits until the water is warm enough for washing clothes. It does this by "feedback" . Information about what is happening is feedback into the robot to tell what to do next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us. So robots are like human beings in two ways. They work and they have feedback. In some ways robots are better than human beings. They work quickly and do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired. So robots are very useful in factories. They can be taught to do many different jobs. First their electronic brain must be shown how the job is done. A person moves the robot's "arms" and "hands" through each part of the job. The most intelligent robots can move and see. Their eyes are cameras. Their fingers can feel shapes and sizes of the objects. These robots have computer brains linked to their eyes and fingers, which control their actions. The expensive robots are used in scientific research. They do such job as handling radioactive materials.

Article: Should students do the grading? The Supreme Court says the practice doesn't violate a student's right to privacy, but is it right for students to grade one another? Walter Potenza, California The Supreme Court was absolutely correct to say it's OK for students to grade one another's homework, quizzes, and tests: in fact, it's a great idea. By grading one another's papers and seeing the problems their classmates have, students double their exposure to the troubles that they may meet on future exams and tests. Grading one another's papers may be one of the best ways for students to _ within themselves the ways to master the most difficult parts of what they are learning. Teachers are underappreciated and underpaid for the number of hours they have to work to be able to teach really well. Grading all their students' papers can take hours. Some of that time and energy can be saved by spending a few minutes in class, while providing an extremely valuable learning experience. I understand that some individuals are sensitive to their classmates seeing their work or grades. Any good teacher would be considerate of students who don't want their classmates to grade their assignments. Winston Smith, North Carolina A girl moves back as her classmate announces her failing test grade and hands her the paper. The quiet classroom heats up. With the increase in student grading over the past few years, scenes like this have become a bitter reality in schools across the nation. Teachers and schools should not advocate student grading and public announcement of grades because it provides a violation of privacy for students and causes unfair judgments and treatment by their classmates. Since 1974, a law known as the Buckley Amendment has forbidden the release of education records in order to protect the privacy of students and their families. I strongly disagree with the Court's ruling that this law does not include student grading. I can think of no greater violation of privacy than the exposure of one's personal information to a group of peers . This can be very embarrassing. Releasing this sort of personal information should be avoided, especially by institutions that seek to provide a supportive environment during essential years of human development.
Question: Walter Potenza suggests that _ .
Options: (A) teachers should set aside some time to grade students' papers (B) the Supreme Court should do more research on students grading (C) teachers should guide students on how to grade homework (D) teachers should be careful not to hurt those sensitive students
