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.

Q: Read the following article and select the best answer. Article: Do you love hamburgers? Do you how they were created? The first hamburgers in U.S. history were served in New Haven, Connecticut, at Louis' Lunch sandwich shop in 1895. Louis Lassen, founder of Louis' Lunch, ran a small lunch wagon selling steak sandwiches to local factory workers. Because he didn't like to waste the excess beef from his daily lunch rush, he ground it up, grilled it, and served it between two slice of bread--and thus America's first hamburger was created. The small _ is still owned and operated by the third and fourth generations of the Lassen family. Hamburgers are still the specialty of the house, where steak is ground fresh each day and hand molded, slow cooked, broiled vertically, and served between two slices of toast with your choice of only three "acceptable" garnishes: cheese, tomato, and onion. Want ketchup or mustard? Forget it. You will be told "no" in no uncertain terms. This is the home of the greatest hamburger in the world, claim the owners, who are perhaps best known for allowing their customers to have a burger the Lassen way or not at all. Question: The best title of this article is _ . - The Creation of hamburgers - Louis' Lunch - A king of fast-food----Hamburgers - Why People Love Hamburgers
