I'm taking a test and have to guess the right answer to the question after the article. Article: Not long ago, the only time you could see a robot was when you were reading a novel or watching a movie such asStar Wars . Today, however, a lot of things in science stories have been science facts. Robots are starting to appear in our everyday lives. These robots have different sizes, shapes, and colors. But they all have the same type of man-made "brain". Leading the robot revolution are industrial robots that work in factories. Industrial robots can do different kinds of jobs that are often boring and sometimes dangerous. Robots are also coming to American homes, though not as quickly as they are entering factories. These robots aren't as friendly and bright as those you saw in Star Wars.But, their makers say, today's home robots "walk", sense objects in their way (and sometimes knock into them), and even carry objects (which they sometimes drop). Well, nobody is perfect. We may laugh at home robot today, but some day they may see and hear better than humans do. We humans can only see certain wavelengths of light, and hear certain sounds. That's because the abilities of our eyes and ears are limited. Robots, however, need not have the same limits as we have. Robot may also be equipped with devices that pick up information humans can't. To understand what their sensing devices pick up is a hard job. Remember, man--made brains handle information, including all kinds of data, as zeroes and ones. Imagine the difficulty in trying to explain to a robot what a football looks like--using only zeroes and ones. Question: From the passage, we can see that factory robots _ . Options: A: help to improve other types of robots B: are most active in industrial revolution C: are playing a more important role than other types of robots D: are the tallest type among robots

I'm taking a test and have to guess the right answer to the question after the article. Article: The H1Nl virus has been spreading world-wide,it is important for us to know how to control it.Please pay attention to the following points: 1.Don't touch your face.Above all,keep your hands away from your eyes,mouth and nose,all of which serve pathways for the viruses to enter your body. 2.Wash your hands.If you have to touch your face,wash your hands,getting under the fingernails for 20 to 30 seconds with hot soap and water before.Soaps with surfactants can deal with flu viruses. 3.Cover your nose and mouth.When someone sneezes or coughs,liquid drops with flu viruses as far as three feet through the air and land on your nose and mouth,so it's best to keep at least an arm's length distance when talking to someone who shows signs of infection .In order to protect others,cover your mouth and nose with a tissue when you cough or sneeze,and clean your hands afterward.Viruses can live for hours,or even longer when on the skin or other surfaces such as keyboards. 4.Consider buying a mask in case you need it in the future.Some research suggests that masks reduce the risk of getting the flu viruses by as much as 80%.But it also suggests that if you don't wash hands,the mask doesn't work well.So wash your hands and use the mask,especially wearing face masks in crowded places is also useful. ,. Question: How long can the viruses live on the skin or other surfaces such as keyboards? Options: A: For an hour. B: For several hours. C: For two weeks. D: For a year.
